eLife Assessment

This manuscript provides a valuable contribution by identifying stress-responsive neurons in the supramammillary nucleus and their ventral subiculum inputs and assessing the regulation of anxiety-related behaviors. The evidence is convincing that the supramammillary nucleus contains stress-responsive neurons, and activation of these neurons increases anxiety-like behaviors. However, evidence that the ventral subiculum input to the supramammillary nucleus encodes and regulates anxiety and that the supramammillary nucleus generates an anxiety engram is incomplete. This work has the potential to offer new insights into how distinct circuits encode different emotional states and will be of interest to those interested in brain systems of aversive emotional and behavioral states.

eLife Assessment

This study presents results supporting a model that tumorous germline stem cells (GSCs) in the Drosophila ovary mimic the stem cell niche and inhibit the differentiation of neighboring cells. The valuable findings show that GSC tumors often contain non-mutant cells whose differentiation is suppressed by the GSC tumorous cells. However, the evidence showing that the GSC tumors produce BMP ligands to suppress differentiation of non-mutant cells is incomplete. It could be strengthened by the use of sensitive RNA in situ hybridization approaches.

eLife Assessment

This manuscript presents significant and important work that advances single-molecule imaging technology of transcription with simultaneous analysis of several parameters. However, currently, the evidence is incomplete and requires further quantitation/description of the technologies used, further controls, and additional analysis of the data by other methods.

eLife Assessment

This study presents a fundamental discovery of how cerebellar climbing fibers modulate plastic changes in the somatosensory cortex by identifying both the responsible cortical circuit and the anatomical pathways. The evidence supporting the conclusions is convincing and well supported by modern neuroscience methodologies. Overall, this work represents a significant contribution that will be of broad interest to neuroscientists, especially those studying the long-distance cerebellar influence on non-motor brain functions.

eLife Assessment

This important work advances our understanding of NMDAR diversity in the brain by providing evidence into the subunit arrangement, architecture, and activation mechanism of GluN1-N2-N3A tri-NMDAR. However, the evidence supporting the conclusions provides incomplete proof for the presence and functional properties of this NMDA receptor subtype. The work will be of broad interest to neuroscientists and biophysicists.

eLife Assessment

This important study sought to investigate the role that early childhood malaria exposure plays in the development of antibody responses to unrelated pathogens and vaccine-derived antigens in Kenyan children. In this natural experiment, the authors compare antibody levels among children who have been exposed to different levels of malaria transmission by using protein microarray technology. Although the findings are of importance, the evidence remains incomplete, and the analysis would benefit from a more in-depth evaluation of potential confounders. With the appropriate analysis, the findings will be of great interest for global health, immunology, and vaccine development.

eLife Assessment

This valuable study uses a sophisticated array of techniques to investigate the mechanisms through which the chordotonal receptors in the locust ear (Müller's organ) sense auditory signals. Ultrastructural reconstruction of the sensory organ provides convincing evidence of the organization of the scolopidial structure that wraps the sensory neuron cilium. However, the recordings of sound-evoked motion and electrophysiological activity from the chordotonal sensory neurons provide incomplete evidence for the proposed axial stretch model of mechanotransduction.

eLife Assessment

Using high-throughput small-molecule screening, this study discloses novel modulators of the mitochondrial transcription factor A (TFAM), a key regulator of mitochondrial function. Reviewers viewed the targeting of TFAM as innovative and the study's conclusions as potentially important (especially the effects on inflammation). However, the lack of evidence for a direct effect of the compounds on TFAM activity weakens the paper's key conclusion and renders the study incomplete.

eLife Assessment

This valuable manuscript presents an open-source and low-cost acoustic system for quantifying biting and chewing in mice. The approach is carefully validated against human observers, demonstrating strong methodological reliability and enabling high-resolution analysis of feeding microstructure. The tool has broad relevance for studies of appetite circuits and pharmacological interventions. A significant contribution is the identification of previously unrecognized "meal-related" neurons in the lateral hypothalamus, providing novel biological insight into food consumption. While the support for the methodological advances is compelling and robust, some circuit-level conclusions are preliminary or incomplete, relying on small pilot samples and manual classification, and should be interpreted with caution. This paper will be of interest to those interested in ingestive behavior and/or hypothalamus.

eLife Assessment

This study presents a useful inventory of genes that are up- and down-regulated in the mouse small intestine (duodenum and ileum) during the first postnatal month; the data were collected and analyzed using solid and validated methodology and can be used as a starting point for additional validation of specific markers and for follow-up functional studies. Some aspects of the study were incomplete, with claims being only partially supported by the data, and it is suggested that additional validation be performed. The authors attempted to correlate gene expression changes with periods of high and low NEC susceptibility, but these correlations are speculative and not supported by functional follow-up studies. Discussion of gene expression changes with NEC susceptibility would be more appropriate to include in the Discussion section and to be tempered in the results section.

eLife Assessment

This valuable study examined the roles of the posterior parietal cortex in rats performing an auditory change-detection decision task. It provided solid evidence for two subpopulations with opposing modulation patterns during decision formation and for a correspondence between neural and behavioral measures of the short timescale used for evidence evaluation.

eLife Assessment

This important study uses a combination of behavioral and molecular techniques to identify neuromodulators that influence blood-feeding behavior in the disease vector, Anopheles stephensi. Through a combination of gene expression analysis and RNA knockdown, the authors identify neuropeptides RYamide and sNPF as candidate regulators for blood-feeding, demonstrate behavioral changes upon co-knockdown, and anatomically characterize their expression patterns. While the evidence for behavioral characterization and expression mapping is solid, the evidence supporting a direct causal role for these neuropeptides in promoting host-seeking remains unproven.

eLife Assessment

This manuscript investigates inter-hemispheric interactions in the olfactory system of Xenopus tadpoles. Using a combination of electrophysiology, pharmacology, imaging, and uncaging, the transection of the contralateral nerve is shown to lead to larger odor responses in the unmanipulated hemisphere, and implicates dopamine signaling in this process. The study uses a rich and sophisticated array of tools to investigate olfactory coding and uncovers valuable mechanisms of signaling. However, the data is incomplete, with a few of the conclusions not being well-supported by the data; the interpretation should be adjusted with some caveats, or additional experiments should be done to support these conclusions.

eLife Assessment

This valuable developmental study provides intriguing but incomplete evidence suggesting that, relative to adults, the enhancement of instrumental learning by Pavlovian bias is most pronounced in adolescence, while reward-induced memory enhancements are strongest in childhood. Although the authors tackle a key aspect of learning and motivation with rigorous experimental methods and sophisticated modeling techniques, there are substantial concerns about the absence of relevant analyses, the lack of accord between model-based and exploratory analyses, and the lack of an explanation for how the results cohere with inconsistent findings in the literature.

eLife Assessment

This study provides a valuable contribution to understanding the functional and molecular organization of the medial nucleus accumbens shell in feeding. Using in vivo imaging, optogenetics, and genetic engineering, the authors present solid evidence for a rostro-caudal gradient in D1-SPN activity that refines earlier pharmacological models. The identification of Stard5 and Peg10 as molecular markers and the creation of a Stard5-Flp line represent meaningful advances for future circuit-specific studies. While stronger integration of molecular and functional results and additional analyses of other Stard5-expressing cell types (e.g., D2-SPNs, interneurons) would enhance completeness, the overall methodological rigor and convergence of findings make this a well-executed and informative study. This will be of interest to those interested in brain circuits, reward, emotion, and feeding behavior.

eLife Assessment

This study presents a valuable in-depth comparison of statistical methods for the analysis of ecological time series data, and shows that different analyses can generate different conclusions, emphasizing the importance of carefully choosing methods and of reporting methodological details. The evidence supporting the claims, based on simulated data for a two-species ecosystem, is solid, although testing on more complex datasets could be of further benefit. This paper should be of broad interest to researchers in ecology.

eLife Assessment

This is an important study of critical period plasticity, focused on temperature manipulations, and how different parts of the Drosophila larval motor circuit adapt or maladapt. The work convincingly demonstrates that components of the motor network respond in distinct ways to the heat shock, and the combination of functional, structural, and electrophysiological approaches makes the study of significant interest. The work points to central interneurons as primary drivers of maladaptive changes, while motoneurons and neuromuscular junctions show compensatory or homeostatic adjustments. The study is methodologically rigorous, contributing significant insights into critical period biology using a tractable invertebrate model.

eLife Assessment

This important work combines theoretical analysis with precise experimental perturbation to demonstrate that the Wnt signaling pathway is characterized by anti-resonance, or a suppression of pathway output at intermediate activation frequencies. The authors identify an anti-resonance behavior, with compelling evidence from optogenetic stimulation in multiple cell types, alongside modeling results that corroborate the phenomenon. While the demonstration of this phenomenon has yet to be extended to fully physiological situations, its clear existence within optogenetically stimulated systems shows that it is likely a significant factor that contributes to the behavior of this central signaling pathway.

eLife Assessment

This important work employed a recent, functional muscle network analysis for evaluating rehabilitation outcomes in post-stroke patients. While the research direction is relevant and suggests the need for further investigation, the strength of evidence supporting the claims is incomplete. Muscle interactions can serve as biomarkers, but improvements in function are not directly demonstrated, and the method's robustness is not benchmarked against existing approaches.
