  eLife Assessment

  In this manuscript, Griesius et al analyze the dendritic integration properties of NDNF and OLM interneurons, and suggest that the supralinear NMDA receptor-dependent synaptic integration may be associated with dendritic calcium transients only in NDNF interneurons. These findings are important because they suggest there might be functional heterogeneities in the mechanisms underlying synaptic integration in different classes of interneurons of the mouse neocortex and hippocampus. The revised work remains incomplete due to remaining concerns about experimental methodology, cell health, and lack of dendritic Na-spikes which have been recorded in previous works.

Activity-dependent lateral inhibition enables the synchronization of olfactory bulb projection neurons

• Curated by eLife

  eLife Assessment

  This important study uses optogenetics in combination with single cell recordings to selectively activate sensory input channels within the olfactory bulb, providing direct evidence for activity-dependent and distance-independent enhancement of stimulus-evoked gamma oscillations via lateral interactions between input channels, most likely via granule cells. The article presents solid evidence to support the main conclusions.

Different serotonergic neurons regulate appetite for sucrose and hunger for proteins

  eLife Assessment

  This study presents the state-dependent role of serotonin for the protein and sugar intake of Drosophila by expressing a dominant-negative serotonin transporter in subsets of serotoninergic neurons. This paper is valuable for neuroscientists working on neuromodulation and the effects of internal states such as hunger, however the characterization of behavioral and neuroanatomical data is incomplete.

Unique longitudinal contributions of sulcal interruptions to reading acquisition in children

• Curated by eLife

  eLife Assessment

  This valuable study relating brain anatomy to reading ability in children studied longitudinally finds that a difference in sulcal anatomy is more predictive of reading ability than cognitive measures. The evidence that this anatomical difference is predictive and confers some benefit in the connectivity between brain areas is based on careful analyses and is solid. The findings would be of interest to researchers studying brain and cognitive development.

  Gil Ávila et al. evaluated the aperiodic component in the medial prefrontal cortex using resting-state EEG recordings from 149 individuals with chronic pain and 115 healthy participants. The authors present compelling evidence that the aperiodic component of the EEG does not differentiate between those with chronic pain and healthy individuals. The study was well-designed and rigorously conducted, and the clear and conclusive results provide important insights that can guide future research in the field of pain neuroscience.

  This valuable study presents new observations on white matter organisation at the micron scale, using a combination of synchrotron imaging and diffusion MRI across two species. Notably, the authors provide solid evidence for the fasciculation of axons within major fibre bundles into laminar structures, though these structures are not consistently observed across modalities or species. The study will be of general interest to neuroanatomists and those interested in white matter imaging.

Nutritional state-dependent modulation of insulin-producing cells in Drosophila

  eLife Assessment

  With compelling electrophysiological and behavioural evidence, this work establishes that the activity of insulin-producing cells (IPCs) depends on the nutritional state in Drosophila and that, like in mammals, there is also an incretin-like effect with IPCs responding to glucose feeding but not to glucose perfusion. Moreover, the authors demonstrate that DH44 neurons respond to glucose perfusion and, together with IPCs, modulate locomotor activity. This important study on the neuronal regulation of metabolic homeostasis will be of interest to both neuroscience and to medical research in diabetes.

  Although others have proposed that OHC electromotility subserves cochlear amplification by acting as a "fluid pump", and evidence for this has been found using electrical stimulation of excised cochleae, this important study substantially advances our understanding of cochlear homeostasis. This is the first report to test the pumping effect in vivo and consider its implications for cochlear homeostasis and drug delivery. The manuscript provides convincing evidence for OHC-based fluid flow within the cochlea.

  The manuscript presents valuable findings of bone remodeling under chronic unpredictable mild stress (CUMS). This is an interesting work on mental stress on bone health and osteoporosis, and the authors offer solid evidence of decreased bone mass mediated by miR-335-3p/Fos signaling in osteoclasts that are involved in the induction of bone loss caused by CUMS. This revised version provided new data that improved the quality of the manuscript and addressed the reviewers' concerns.
