     This is a compelling study on pro-inflammatory and anti-inflammatory lipids in relation to skeletal muscle injury. It convincingly identifies pro-inflammatory lipids during recovery predisposing to fibrosis, and maresin 1 as an anti-inflammatory lipid reducing fibrosis, improved muscle regeneration, partially restoring contractile function, of fundamental potential clinical application.

     The authors introduce a potentially valuable novel method that provides trial-by-trial probabilistic estimates of learning and decision-making strategies inferred from choice behavior across species. This approach could prove more useful over traditional techniques for arbitrating between strategies and detecting when learning happens, and because it is computationally lightweight. Reviewers identified several concerns that limit the strength of the evidence provided, rendering the findings incomplete.

     George et al. present a convincing new Python toolbox ("RatInABox") that allows researchers to generate synthetic behavior and neural data specifically focusing on hippocampal functional cell types (place cells, grid cells, boundary vector cells, head direction cells).

     This is valuable for theory-driven research where synthetic benchmarks should be used. Beyond just navigation, it can be highly useful for novel tool development that requires jointly modeling behavior and neural data. The authors provide convincing evidence of its utility with well documented and easy to use code and the corresponding manuscript.

     This potentially valuable study provides some evidence that upregulation of sodium-activated potassium channels contributes to neuronal hyperexcitability and seizures following traumatic brain injury. However, the evidence supporting a direct link is incomplete. This work will be of interest to epilepsy and ion channel researchers.

     This paper provides valuable insights into the consequences of hydrogen sulfide (H2S) exposure on the behavior and physiology of the nematode C. elegans. While solid evidence supports most of the paper's findings, the evidence that H2S is detected by the nervous system to mediate behavioral avoidance is incomplete. The paper provides a wide range of intriguing observations that could serve as a foundation for future work to synthesize these disparate results or provide insight into the mechanisms of H2S detection in C. elegans.

     In this important study, Guma and colleagues describe the use of structural neuroimaging to assess the cross-species convergence of sex differences in global and regional brain volumes in humans and mice. The goal of the work is to inform to what extent mouse studies of these aforementioned sex differences have relevance to humans. The authors suggest which aspects of brain anatomy (as measured by volume) are conserved or not, across species, which has theoretical and practical implications beyond a single sub-field. The evidence to support the findings is solid, it uses methods and data analysis that are appropriate and validated.

     This important work advances our understanding of how brains flexibly gate actions in different contexts, a topic of great interest to the broader field of systems neuroscience. Recording neural activity from several sensory and motor cortical areas along a sensorimotor pathway, the authors found that preparatory activity in motor cortical areas of the mouse depends on the context in which an action will be carried out, consistent with previous theoretical and experimental work. Furthermore, the authors provide causal evidence that these changes support flexible gating of actions. The carefully carried out experiments were analyzed using state-of-the-art methodology and provide convincing conclusions.

     This important work provides insight into the activity and spatial organization of synapses during early postnatal development in the mouse visual cortex, using state-of-the-art tools to show that synapses are distributed in co-active clusters well before eye opening. The evidence supporting the claims is convincing, and this revised version provides additional methodological details about the experimental paradigm and image analysis.. This work is of particular interest to the field of developmental neuroscience and can also be used by computational neuroscientists studying dendritic integration.

     The contributions of ipsilateral cortical pathways to motor control are yet not fully understood. Here, the authors present important insights into their role in locomotion following unilateral spinal cord injury. Their data provide convincing evidence in rats that stimulation of ipsilateral motor cortex improves the injured side's ability to support weight and leads to improved locomotion, a result that may inspire new treatments for spinal or cerebral injuries.

      This study investigates BMP signaling mechanisms in the developing chick cerebellum to better understand germinal layer formation, cellular amplification and neuronal differentiation. The data from human tissue is compelling and lends support to the possible links of these processes to medulloblastoma, although this study does raise exciting questions regarding the generalized role of BMP signaling during normal development and malignant growth. Overall, this is an important study with beautifully presented findings.
