Dear Editor,
We would like to submit the enclosed manuscript entitled "GDNF Acutely Modulates
Neuronal Excitability and A-type Potassium Channels in Midbrain Dopaminergic Neurons",
which we wish to be considered for publication in Nature Neuroscience,
GDNF has long been thought to be a potent neurotrophic factor for the survival of midbrain
dopaminergic neurons,which are degenerated in Parkinson’s disease,In this paper,we
report an unexpected,acute effect of GDNF on A-type potassium channels,leading to a
potentiation of neuronal excitability,in the dopaminergic neurons in culture as well as in
adult brain slices,Further,we show that GDNF regulates the K+ channels through a
mechanism that involves activation of MAP kinase,Thus,this study has revealed,for the
first time,an acute modulation of ion channels by GDNF,Our findings challenge the classic
view of GDNF as a long-term survival factor for midbrain dopaminergic neurons,and
suggest that the normal function of GDNF is to regulate neuronal excitability,and
consequently dopamine release,These results may also have implications in the treatment
of Parkinson’s disease.
Due to a direct competition and conflict of interest,we request that Drs,XXX of Harvard
Univ.,and YY of Yale Univ,not be considered as reviewers,With thanks for your
consideration,I am
Sincerely yours,
Dear Editor,
We would like to submit the enclosed manuscript entitled "Ca2+-binding protein frequenin
mediates GDNF-induced potentiation of Ca2+ channels and transmitter release",which we wish
to be considered for publication in Neuron,
We believe that two aspects of this manuscript will make it interesting to general readers of
Neuron,First,we report that GDNF has a long-term regulatory effect on neurotransmitter
release at the neuromuscular synapses,This provides the first physiological evidence for a role
of this new family of neurotrophic factors in functional synaptic transmission,Second,we
show that the GDNF effect is mediated by enhancing the expression of the Ca2+-binding
protein frequenin,Further,GDNF and frequenin facilitate synaptic transmission by enhancing
Ca2+ channel activity,leading to an enhancement of Ca2+ influx,Thus,this study has identified,
for the first time,a molecular target that mediates the long-term,synaptic action of a
neurotrophic factor,Our findings may also have general implications in the cell biology of
neurotransmitter release.
Dear Editor:
Enclosed are copies of a manuscript entitled "BDNF and NT-4/5 Promote the Development of
Long-Term Potentiation in the Hippocampus",which we wish to be considered for publication in
Nature,As you know,there is a great deal of interest and excitement recently in understanding the
role of neurotrophins in synapse development and plasticity,Our manuscript provides,for the first
time,the physiological evidence that neurotrophins regulate long-term potentiation (LTP),The
main point of the paper is that the neurotrophins BDNF and NT-4 induce an earlier appearance of
LTP in developing hippocampus,In contrast to recent Science article by XX's group,we (and
several other LTP groups) did not see that BDNF enhance basal synaptic transmission in adullt
hippocampus,However,we found that in adult hippocampus,inhibition of BDNF/TrkB activity
attenuated LTP,and weak tetanus that normally cannot induce LTP produced enduring LTP,These
findings may have implications in the basic mechanism for regulation of synapse development and
long-term modulation of synaptic efficacy.
Because of the rather competitive nature of the field and the important implication of our findings,
we have not yet presented this work in any public forum,However,confidential discussion with
several prominent neuroscientists such as 111 and 222 have generated tremendous excitement.
Thus,we feel that this work is of general interest and is suitable for publication in Nature,We
would like to suggest Drs,aaa of Yale Univ.,bbb of Harvard Medical School,and ccc of Univ,of
California-Berkeley,as reviewers for this manuscript,Due to a direct competition and conflict of
interest,we request that Dr,XX and YY,not be considered as reviewers.
Thank you very much for your consideration.

Formation of the normal mammalian cerebral cortex requires the migration of
GABAergic inhibitory interneurons from an extracortical origin,the lateral ganglionic
eminence (LGE),Mechanisms guiding the migratory direction of these neurons,or
other neurons in the neocortex,are not well understood,We have used an explant assay
to study GABAergic neuronal migration and found that the ventricular zone (VZ) of
the LGE is repulsive to GABAergic neurons,Furthermore,the secreted protein Slit is a
chemorepellent guiding the migratory direction of GABAergic neurons,and blockade
of endogenous Slit signaling inhibits the repulsive activity in the VZ,These results have
revealed a cellular source of guidance for GABAergic neurons,demonstrated a
molecular cue important for cortical development,and suggested a guidance
mechanism for the migration of extracortical neurons into the neocortex.
It has not escaped our notice that the specific pairing we have postulated
immediately suggests a possible copying mechanism for the genetic material.

Neuronal responses to brain-derived neurotrophic factor (BDNF) are initiated by the activation of the
receptor TrkB tyrosine kinase (1),In this study we examined whether cholesterol- and glycolipid-rich
microdomains,lipid rafts,provide a functional platform for BDNF-dependent signal transduction (2),Using
primary culture of cortical neurons,we demonstrated that TrkB was dramatically translocated into lipid
rafts in BDNF-dependent manner (3),This translocation was blocked by the pharmacological effect of
general Trk inhibitors,indicating that TrkB activation is required for the translocation mechanism,We also
showed that BDNF and TrkB-FL were both concentrated in lipid rafts during development of cerebral cortex,
concomitant with that of synaptic vesicle proteins,including soluble N-ethylmaleimide-sensitive factor
attachment protein receptor (SNARE) proteins and synaptophysin (4),This result,together with the findings
that BDNF stimulation caused translocation of synaptophysin into lipid rafts (5) and that BDNF-enhanced
glutamate release and exocytosis were both attenuated by depletion of cholesterol from the cell surface with
methyl-beta-cyclodextrin (MCD),indicates that lipid rafts are essential for BDNF regulation of
neurotransmitterrelease (6).
Brain-derived neurotrophic factor (BDNF) plays an important role in synaptic plasticity but
the underlying signaling mechanisms remain unknown,Here we show that BDNF rapidly
recruits full-length TrkB (TrkB-FL) receptor into cholesterol-rich lipid rafts from non-raft
regions of neuronal plasma membranes,Truncated TrkB lacking the intracellular kinase
domain was not translocated,and the translocation of TrkB-FL was blocked by Trk inhibitors,
suggesting a role for TrkB tyrosine kinase in the translocation,Disruption of lipid rafts by
depleting cholesterol from the cell surface blocked BDNF-dependent TrkB translocation.
Disruption of rafts also prevented the potentiating effect of BDNF on transmitter release in
cultured neurons,as well as that on synaptic response to tetanus in hippocampal slices,In
contrast,lipid rafts are not required for BDNF regulation of neuronal survival,Thus,ligand-
induced TrkB translocation into lipid rafts may represent a selective signaling mechanism for
synaptic modulation by BDNF in the CNS.
A calcium-independent but voltage-dependent secretion (CIVDS) coexists with the calcium
dependent exocytosis in dorsal root ganglion (DRG) neurons (1),Here we have investigated
the CIVDS-coupled endocytosis (2),Using optical and membrane capacitance
measurements,we show that,in calcium-free medium,either step depolarization or a train
of action-potential-like stimulation induce a novel form of rapid endocytosis,which occurs
immediately after the CIVDS,Surprisingly,this calcium-independent endocytosis is
strongly dependent on the stimulation frequency (3),H7 suppress the endocytosis,while
PKA agonists enhance it (4),Biochemical experiments show that membrane depolarization
directly up-regulate PKA in DRG neurons,Our experiments also showed that the
frequency dependency of CIVDS-RE is dynamin-independent (5),Thus,our data indicate
that neuronal activity modulates a rapid endocytosis via a Ca2+- and dynamin-independent
phosphorylation-dependent manner in DRG neurons (6),
Synaptic vesicle endocytosis is believed to require Ca2+ and the GTPase dynamin,Here we
report a novel form of rapid endocytosis (RE) that is independent of Ca2+ and dynamin in
dorsal root ganglion (DRG) neurons,Using FM dye labeling and membrane capacitance
measurements,we show that both step depolarization and repetitive stimulation induce RE
in Ca2+-free medium,RE also occurs in the presence of a Ca2+ chelator (BAPTA),
Inhibition of dynamin function by three different approaches does not affect RE,Protein
kinase A (PKA) inhibitors suppress the endocytosis,while PKA activators enhance it.
Biochemical experiments demonstrate that membrane depolarization directly up-regulated
PKA activity,These results reveal a Ca2+- and dynamin-independent form of endocytosis
that is controlled by neuronal activity and PKA-dependent phosphorylation in DRG
neurons,

In this study we have examined the role of chromogranins CGA and CGB,in dense-core
secretory granule biogenesis,We analyzed the effect of specific depletion of either CGA
or CGB,using an antisense RNA strategy,on dense-core secretory granule formation in
rat pheochromocytoma (PC12) cells,a model neuroendocrine cell line,We also
expressed CGA in a pituitary cell line (6T3) lacking the regulated secretory pathway and
nonendocrine fibroblast cells to determine its effect on induction of dense-core secretory
granule biogenesis and regulated secretion,Finally,we determined whether CGA could
regulate the level of other secretory granule proteins in neuroendocrine and endocrine
cells,PC12 and 6T3,These studies identified CGA as a key regulator of dense-core
secretory granule biogenesis and storage of other granule proteins in endocrine cells.

Previous studies have shown that membrane depolarization-triggered Ca2+ influx
through L-type VSCCs induces an increase in BDNF mRNA expression in cultured
neurons (Zafra et al.,1990 ; Ghosh et al.,1994 ),This increase in BDNF mRNA could
be the result of increased transcription initiation,or increased BDNF mRNA stability,or
both,To determine if membrane depolarization stimulates BDNF transcription,we….
Given the finding that Ca2+ influx through L-type VSCCs induces BDNF transcription,
experiments were carried out to determine which of the four BDNF promoters is capable
of mediating a Ca2+ response,As described above,the rat BDNF gene consists of four
distinct 5' exons each driven by a specific promoter and each spliced to a common 3'
exon that encodes the BDNF protein,Since each of the four primary BDNF transcripts
can be polyadenylated at one of two sites,a total of eight BDNF transcripts are
generated,In principle,the eight transcripts can be distinguished by Northern blotting
using 5'exon–specific probes,since each of the four 5' exon probes should detect a short
and a long BDNF transcript,By identifying the specific BDNF mRNAs induced upon
Ca2+ influx through L-type VSCCs,it should be possible to identify which of the four
BDNF promoters is Ca2+ responsive,since the Ca2+-responsive promoter(s) would be
expected to be located just 5' of the initiation site of BDNF mRNA synthesis.

Dear Editor,
I would appreciate if you could reconsider to review our manuscript,“111." We
feel strongly that this is an important subject that touches one of the central dogmas in
neuroscience,xxx,It is also very timely,given the publication of the paper by X and Y
entitled,222” in the latest issue of Nature Neuroscience,In this paper,the authors
xxx,They claimed that xxx,When a paper this provocative has been published by a
high profile journal like Nature Neuroscience,we believe that it is worth giving a
benefit of doubts,It will be helpful if there are papers that consider other alternative
interpretations,or attempt to replicate in the same or different systems,
We have observed similar xxx,but we have a completely different interpretation,
We found that 1) xxx 2) xxx; 3) xxx,Thus,our paper raises the possibility that xxx
reported by X and Y were due to xxx,Specifically,we would like you to consider the
following two issues,First,X and Y used aaa,while we used bbb,sssssssss,Second,
ccc used by X and Y may not be so specific,
In addition to the drastically different opinions regarding xxx,we feel that our
findings on xxx is also significant in yyy and will be of interests to general readers of
Nature Neuroscience,We therefore did not write our paper to directly challenge the
paper by X and Y,However,we will be willing to re-write the paper in ways you think
that will help debate on this important issue.
When your paper gets rejected — with review
Dear Dr,xx,
We received with some surprise your letter of November 4,rejecting this manuscript on
the basis of one reviewer’s opinion which you,found persuasive”,We wish to indicate our
dissatisfaction with this reviewer’s comments,which appear to ignore the new experiments
submitted as part of the revised manuscript.
This reviewer states:,111.” This was precisely the point of the xxx experiment which
indicated that there were no such deficits.
This reviewer further states:,222.” Again,this is a mystifying statement as the detailed
rebuttal accompanying this letter described the xxx,Did the reviewer not understand that
xxx?
Finally,concerning the proposal for a xxx experiment,we believe that you and this
reviewer already know that xxx,Thus,it is impossible to do such experiments.
While we recognize that the final decision is yours,we feel that reviewer#1 is being
unreasonable,We would greatly appreciate it if you would submit this manuscript,
reviewer#1’s comments,and our rebuttals,to an additional unbiased reviewer,We would be
most surprised if the new reviewer would see the comments of the reviewer#1 as reasonable,
but if he/she did so,we would accept a negative decision gracefully.
Is it a good paper or not?
what makes a great paper?
– Astounding work
– of great value to its own field and/or to the general readership
Common problems resulting in rejection of a
manuscript
– too small of an advance
– not of general interest/ belongs in specialized journal
– not scientifically convincing,interpretations poorly supported
– results not well interpreted,poor context

Dear Editor,
We would like to submit the enclosed manuscript entitled "GDNF Acutely Modulates
Neuronal Excitability and A-type Potassium Channels in Midbrain Dopaminergic Neurons",
which we wish to be considered for publication in Nature Neuroscience,
GDNF has long been thought to be a potent neurotrophic factor for the survival of midbrain
dopaminergic neurons,which are degenerated in Parkinson’s disease,In this paper,we
report an unexpected,acute effect of GDNF on A-type potassium channels,leading to a
potentiation of neuronal excitability,in the dopaminergic neurons in culture as well as in
adult brain slices,Further,we show that GDNF regulates the K+ channels through a
mechanism that involves activation of MAP kinase,Thus,this study has revealed,for the
first time,an acute modulation of ion channels by GDNF,Our findings challenge the classic
view of GDNF as a long-term survival factor for midbrain dopaminergic neurons,and
suggest that the normal function of GDNF is to regulate neuronal excitability,and
consequently dopamine release,These results may also have implications in the treatment
of Parkinson’s disease.

Sincerely yours,
Dear Editor,
We would like to submit the enclosed manuscript entitled "Ca2+-binding protein frequenin
mediates GDNF-induced potentiation of Ca2+ channels and transmitter release",which we wish
to be considered for publication in Neuron,
We believe that two aspects of this manuscript will make it interesting to general readers of
Neuron,First,we report that GDNF has a long-term regulatory effect on neurotransmitter
release at the neuromuscular synapses,This provides the first physiological evidence for a role
of this new family of neurotrophic factors in functional synaptic transmission,Second,we
show that the GDNF effect is mediated by enhancing the expression of the Ca2+-binding
protein frequenin,Further,GDNF and frequenin facilitate synaptic transmission by enhancing
Ca2+ channel activity,leading to an enhancement of Ca2+ influx,Thus,this study has identified,
for the first time,a molecular target that mediates the long-term,synaptic action of a
neurotrophic factor,Our findings may also have general implications in the cell biology of
neurotransmitter release.
Dear Editor:
Enclosed are copies of a manuscript entitled "BDNF and NT-4/5 Promote the Development of
Long-Term Potentiation in the Hippocampus",which we wish to be considered for publication in
Nature,As you know,there is a great deal of interest and excitement recently in understanding the
role of neurotrophins in synapse development and plasticity,Our manuscript provides,for the first
time,the physiological evidence that neurotrophins regulate long-term potentiation (LTP),The
main point of the paper is that the neurotrophins BDNF and NT-4 induce an earlier appearance of
LTP in developing hippocampus,In contrast to recent Science article by XX's group,we (and
several other LTP groups) did not see that BDNF enhance basal synaptic transmission in adullt
hippocampus,However,we found that in adult hippocampus,inhibition of BDNF/TrkB activity
attenuated LTP,and weak tetanus that normally cannot induce LTP produced enduring LTP,These
findings may have implications in the basic mechanism for regulation of synapse development and
long-term modulation of synaptic efficacy.
Because of the rather competitive nature of the field and the important implication of our findings,
we have not yet presented this work in any public forum,However,confidential discussion with
several prominent neuroscientists such as 111 and 222 have generated tremendous excitement.
Thus,we feel that this work is of general interest and is suitable for publication in Nature,We
would like to suggest Drs,aaa of Yale Univ.,bbb of Harvard Medical School,and ccc of Univ,of
California-Berkeley,as reviewers for this manuscript,Due to a direct competition and conflict of
interest,we request that Dr,XX and YY,not be considered as reviewers.
Thank you very much for your consideration.

Formation of the normal mammalian cerebral cortex requires the migration of
GABAergic inhibitory interneurons from an extracortical origin,the lateral ganglionic
eminence (LGE),Mechanisms guiding the migratory direction of these neurons,or
other neurons in the neocortex,are not well understood,We have used an explant assay
to study GABAergic neuronal migration and found that the ventricular zone (VZ) of
the LGE is repulsive to GABAergic neurons,Furthermore,the secreted protein Slit is a
chemorepellent guiding the migratory direction of GABAergic neurons,and blockade
of endogenous Slit signaling inhibits the repulsive activity in the VZ,These results have
revealed a cellular source of guidance for GABAergic neurons,demonstrated a
molecular cue important for cortical development,and suggested a guidance
mechanism for the migration of extracortical neurons into the neocortex.
It has not escaped our notice that the specific pairing we have postulated
immediately suggests a possible copying mechanism for the genetic material.

Neuronal responses to brain-derived neurotrophic factor (BDNF) are initiated by the activation of the
receptor TrkB tyrosine kinase (1),In this study we examined whether cholesterol- and glycolipid-rich
microdomains,lipid rafts,provide a functional platform for BDNF-dependent signal transduction (2),Using
primary culture of cortical neurons,we demonstrated that TrkB was dramatically translocated into lipid
rafts in BDNF-dependent manner (3),This translocation was blocked by the pharmacological effect of
general Trk inhibitors,indicating that TrkB activation is required for the translocation mechanism,We also
showed that BDNF and TrkB-FL were both concentrated in lipid rafts during development of cerebral cortex,
concomitant with that of synaptic vesicle proteins,including soluble N-ethylmaleimide-sensitive factor
attachment protein receptor (SNARE) proteins and synaptophysin (4),This result,together with the findings
that BDNF stimulation caused translocation of synaptophysin into lipid rafts (5) and that BDNF-enhanced
glutamate release and exocytosis were both attenuated by depletion of cholesterol from the cell surface with
methyl-beta-cyclodextrin (MCD),indicates that lipid rafts are essential for BDNF regulation of
neurotransmitterrelease (6).
Brain-derived neurotrophic factor (BDNF) plays an important role in synaptic plasticity but
the underlying signaling mechanisms remain unknown,Here we show that BDNF rapidly
recruits full-length TrkB (TrkB-FL) receptor into cholesterol-rich lipid rafts from non-raft
regions of neuronal plasma membranes,Truncated TrkB lacking the intracellular kinase
domain was not translocated,and the translocation of TrkB-FL was blocked by Trk inhibitors,
suggesting a role for TrkB tyrosine kinase in the translocation,Disruption of lipid rafts by
depleting cholesterol from the cell surface blocked BDNF-dependent TrkB translocation.
Disruption of rafts also prevented the potentiating effect of BDNF on transmitter release in
cultured neurons,as well as that on synaptic response to tetanus in hippocampal slices,In
contrast,lipid rafts are not required for BDNF regulation of neuronal survival,Thus,ligand-
induced TrkB translocation into lipid rafts may represent a selective signaling mechanism for
synaptic modulation by BDNF in the CNS.
A calcium-independent but voltage-dependent secretion (CIVDS) coexists with the calcium
dependent exocytosis in dorsal root ganglion (DRG) neurons (1),Here we have investigated
the CIVDS-coupled endocytosis (2),Using optical and membrane capacitance
measurements,we show that,in calcium-free medium,either step depolarization or a train
of action-potential-like stimulation induce a novel form of rapid endocytosis,which occurs
immediately after the CIVDS,Surprisingly,this calcium-independent endocytosis is
strongly dependent on the stimulation frequency (3),H7 suppress the endocytosis,while
PKA agonists enhance it (4),Biochemical experiments show that membrane depolarization
directly up-regulate PKA in DRG neurons,Our experiments also showed that the
frequency dependency of CIVDS-RE is dynamin-independent (5),Thus,our data indicate
that neuronal activity modulates a rapid endocytosis via a Ca2+- and dynamin-independent
phosphorylation-dependent manner in DRG neurons (6),
Synaptic vesicle endocytosis is believed to require Ca2+ and the GTPase dynamin,Here we
report a novel form of rapid endocytosis (RE) that is independent of Ca2+ and dynamin in
dorsal root ganglion (DRG) neurons,Using FM dye labeling and membrane capacitance
measurements,we show that both step depolarization and repetitive stimulation induce RE
in Ca2+-free medium,RE also occurs in the presence of a Ca2+ chelator (BAPTA),
Inhibition of dynamin function by three different approaches does not affect RE,Protein
kinase A (PKA) inhibitors suppress the endocytosis,while PKA activators enhance it.
Biochemical experiments demonstrate that membrane depolarization directly up-regulated
PKA activity,These results reveal a Ca2+- and dynamin-independent form of endocytosis
that is controlled by neuronal activity and PKA-dependent phosphorylation in DRG
neurons,

In this study we have examined the role of chromogranins CGA and CGB,in dense-core
secretory granule biogenesis,We analyzed the effect of specific depletion of either CGA
or CGB,using an antisense RNA strategy,on dense-core secretory granule formation in
rat pheochromocytoma (PC12) cells,a model neuroendocrine cell line,We also
expressed CGA in a pituitary cell line (6T3) lacking the regulated secretory pathway and
nonendocrine fibroblast cells to determine its effect on induction of dense-core secretory
granule biogenesis and regulated secretion,Finally,we determined whether CGA could
regulate the level of other secretory granule proteins in neuroendocrine and endocrine
cells,PC12 and 6T3,These studies identified CGA as a key regulator of dense-core
secretory granule biogenesis and storage of other granule proteins in endocrine cells.

Previous studies have shown that membrane depolarization-triggered Ca2+ influx
through L-type VSCCs induces an increase in BDNF mRNA expression in cultured
neurons (Zafra et al.,1990 ; Ghosh et al.,1994 ),This increase in BDNF mRNA could
be the result of increased transcription initiation,or increased BDNF mRNA stability,or
both,To determine if membrane depolarization stimulates BDNF transcription,we….
Given the finding that Ca2+ influx through L-type VSCCs induces BDNF transcription,
experiments were carried out to determine which of the four BDNF promoters is capable
of mediating a Ca2+ response,As described above,the rat BDNF gene consists of four
distinct 5' exons each driven by a specific promoter and each spliced to a common 3'
exon that encodes the BDNF protein,Since each of the four primary BDNF transcripts
can be polyadenylated at one of two sites,a total of eight BDNF transcripts are
generated,In principle,the eight transcripts can be distinguished by Northern blotting
using 5'exon–specific probes,since each of the four 5' exon probes should detect a short
and a long BDNF transcript,By identifying the specific BDNF mRNAs induced upon
Ca2+ influx through L-type VSCCs,it should be possible to identify which of the four
BDNF promoters is Ca2+ responsive,since the Ca2+-responsive promoter(s) would be
expected to be located just 5' of the initiation site of BDNF mRNA synthesis.

Dear Editor,
I would appreciate if you could reconsider to review our manuscript,“111." We
feel strongly that this is an important subject that touches one of the central dogmas in
neuroscience,xxx,It is also very timely,given the publication of the paper by X and Y
entitled,222” in the latest issue of Nature Neuroscience,In this paper,the authors
xxx,They claimed that xxx,When a paper this provocative has been published by a
high profile journal like Nature Neuroscience,we believe that it is worth giving a
benefit of doubts,It will be helpful if there are papers that consider other alternative
interpretations,or attempt to replicate in the same or different systems,
We have observed similar xxx,but we have a completely different interpretation,
We found that 1) xxx 2) xxx; 3) xxx,Thus,our paper raises the possibility that xxx
reported by X and Y were due to xxx,Specifically,we would like you to consider the
following two issues,First,X and Y used aaa,while we used bbb,sssssssss,Second,
ccc used by X and Y may not be so specific,
In addition to the drastically different opinions regarding xxx,we feel that our
findings on xxx is also significant in yyy and will be of interests to general readers of
Nature Neuroscience,We therefore did not write our paper to directly challenge the
paper by X and Y,However,we will be willing to re-write the paper in ways you think
that will help debate on this important issue.
When your paper gets rejected — with review
Dear Dr,xx,
We received with some surprise your letter of November 4,rejecting this manuscript on
the basis of one reviewer’s opinion which you,found persuasive”,We wish to indicate our
dissatisfaction with this reviewer’s comments,which appear to ignore the new experiments
submitted as part of the revised manuscript.
This reviewer states:,111.” This was precisely the point of the xxx experiment which
indicated that there were no such deficits.
This reviewer further states:,222.” Again,this is a mystifying statement as the detailed
rebuttal accompanying this letter described the xxx,Did the reviewer not understand that
xxx?
Finally,concerning the proposal for a xxx experiment,we believe that you and this
reviewer already know that xxx,Thus,it is impossible to do such experiments.
While we recognize that the final decision is yours,we feel that reviewer#1 is being
unreasonable,We would greatly appreciate it if you would submit this manuscript,
reviewer#1’s comments,and our rebuttals,to an additional unbiased reviewer,We would be
most surprised if the new reviewer would see the comments of the reviewer#1 as reasonable,
but if he/she did so,we would accept a negative decision gracefully.
Is it a good paper or not?
what makes a great paper?
– Astounding work
– of great value to its own field and/or to the general readership
Common problems resulting in rejection of a
manuscript
– too small of an advance
– not of general interest/ belongs in specialized journal
– not scientifically convincing,interpretations poorly supported
– results not well interpreted,poor context
