Argunşah et al. investigate the mechanisms underlying the differential response dynamics of barrel vs septa domains in shaping the responses to single vs multiple whiskers. Based on the observation of a higher density of SST+ interneurons in the septa, the authors investigate the hypothesis that Elfn1-dependent short-term plasticity shapes these responses. This important study is, however, supported by incomplete evidence; factors restricting the strength of evidence are the limited spatial resolution of the multi-unit activity, as well as the lack of a mechanistic explanation. This provocative and intellectually stimulating hypothesis provides a contribution to work on how different cell types shape cortical representation.

This useful study investigates noise-robust and energy-efficient circuit mechanisms for working memory by optimizing connectivity and reports that the resulting networks exhibit rotational dynamics and better match aspects of PFC population recording. However, the supporting evidence remains incomplete, given the restricted linear, task-specific training and analysis, and limited comparisons with other prominent models. The manuscript would be strengthened by extending the analysis to nonlinear dynamics, providing more rigorous comparisons with alternative models, and establishing a stronger link to prior theoretical and experimental work.

This paper addresses a valuable research question on the modest heritability of the brain's response to movie watching, and how heritability varies under different parameters such as regional spatial hyperalignment and BOLD frequency bands. The topic of this paper is of interest to fMRI methodological experts, and potentially to a broader cognitive neuroscience audience, and those with an interest in understanding the heritable sources of individual differences in brain function. Although some of the conclusions could be strengthened by future cross validation studies in independent and larger family-based samples, and through complementary twin/family and SNP-based models, taken altogether, the analyses and results provide convincing evidence for the overall conclusions.

This paper reports the findings of a neuroimaging experiment that tested the hypothesis that the cortex, specifically early visual areas, reinstates certain content from past episodic events. This is a useful study that highlights the role of early sensory cortices in supporting rapid, one-shot learning of location information for long-term memory. The strength of the evidence is solid, with the methods, data, and analyses broadly supporting the claims.

This study presents a valuable and well-documented computational pipeline for the scalable analysis and spike sorting of large extracellular electrophysiology datasets, with particular relevance for high-density recordings such as Neuropixels. The authors demonstrate the pipeline's utility for benchmarking spike sorter performance and evaluating the effects of data compression, supported by thorough testing, clear figures, and openly available code. The workflow is reproducible, portable, and practical, providing concrete guidance on computational cost and runtime. Overall, the evidence supporting the pipeline's performance and output quality is compelling, and this work will be of broad interest to the systems neuroscience community.

This important study shows that long-range somatostatin-expressing neurons in the ventrolateral periaqueductal grey that project to the rostral ventromedial medulla selectively suppress pain responses during conditioned fear. The evidence supporting these conclusions is exceptional, with methods spanning a novel cued fear-conditioned analgesia paradigm, cell-type-specific optogenetic activation and inhibition, anatomical circuit tracing, and in vivo spinal cord electrophysiology. These results will be of broad interest to systems and behavioral neuroscientists studying fear, pain, and descending pain-control circuitry.

This study provides fundamental insights into the mechanisms of visual object categorization in primates through a scalable behavioral framework for assessing category learning and generalization in macaque monkeys. The evidence is compelling, based on extensive behavioral characterization, rigorous control experiments, and comprehensive comparisons with humans and computational models, although extending the model analyses to the secondary monkey experiments would further strengthen the conclusions.

This study presents a platform to implement closed-loop experiments in mice based on auditory feedback. The authors provide convincing evidence that their platform enables a variety of closed-loop experiments using neural or movement signals, indicating that it will be a valuable resource to the neuroscience community. The authors make this platform more accessible by complementing the paper with a detailed tutorial explaining how to implement the software and hardware.

The article presents important findings of a dissociation between phasic and tonic pain functions in adaptive behavior, combining immersive VR, computational modeling, skin conductance, and EEG data. The methodology used is convincing. Its ecological design and sophisticated computational modeling are major strengths.

The authors show that innate defensive behavior in mice is shaped by threat intensity, reward value, and social hierarchy, highlighting how value and social context influence instinctive decisions. The authors provide a valuable characterization of escape behavior which approximates naturalistic conditions. Despite minor methodological limitations, the work provides a solid foundation for future investigation of how reward and social context interact to influence behavior.
