This valuable manuscript reveals sex differences in bi-conditional Pavlovian learning and conditional behavior. Males learn hierarchical context-cue-outcome associations more quickly, but females show more stable and robust task performance. These sex differences are related to cellular activation in the orbitofrontal cortex. Although the evidence supporting these claims is convincing, some assertions of sex differences in context-dependent discrimination behaviour may be slightly overstated yet have strong potential to guide future research to clarify the nature of these differences. The results will be of interest to many behavioural neuroscientists, particularly those who investigate sex-specific behaviours.

In this fundamental study, authors present compelling evidence for the diversity in cellular and synaptic properties of one class of spinal interneurons and tie it to their differentiated role in locomotor pattern generation. The findings reported here will be of broad interest to neuroscientists in general and to motor systems scientists in particular.

The study presents an important ecosystem designed to support literature mining in biomedical research, showcasing a methodological framework that includes tools like Pubget for article collection and labelbuddy for text annotation. The solid evidence presented for these tools suggests they could streamline the analysis and annotation of scientific literature, potentially benefiting research across a range of biomedical disciplines. While the primary focus is on neuroimaging literature, the applicability of these methods and tools might extend further, offering an advance in the practices of meta-research and literature mining.

This study builds upon previous work which demonstrated that brain injury results in the entry of a protein called albumin into the brain which then causes diverse effects. The present study shows that prolonged stimulation of a forelimb in a rat leads to albumin entry, and is associated with effects that suggest plasticity is enhanced in the stimulated side of the brain. The strength of evidence was convincing and results are important because they suggest a previously-considered pathological process may be relevant to the normal brain and have benefits.

fMRI was used to address an important aspect of human cognition - the capacity for structured representations and symbolic processing - in a cross-species comparison with macaques; the experimental design probed implicit symbolic processing through reversal of learned stimulus pairs. The authors present solid evidence in humans that helps elucidate the role of brain networks in symbolic processing, however the evidence from macaques was necessarily incomplete (e.g., hard-to-quantify differences in learning trajectories and lived experience between species).

This important work advances our understanding of the differences in locomotion-induced modulation in primate and rodent visual cortexes and underlines the significant contribution cross-species comparisons make to investigating brain function. The evidence in support of these differences across species is convincing. This work will be of broad interest to neuroscientists.

This manuscript provides a valuable demonstration that distractor effects in multi-attribute decision-making correlate with the form of attribute integration (additive vs. multiplicative). The evidence supporting the conclusions is convincing, but there are questions about how to interpret the findings. The manuscript will be interesting to decision-making researchers in neuroscience, psychology, and related fields.

The aim of this important study is to functionally characterize neuronal circuits underlying the escape behavior in Drosophila larvae. Upon detection of a noxious stimulus, larvae follow a series of stereotyped movements that include bending of their body, rolling and crawling away. This paper combines quantitative behavioral analyses, cell-type specific manipulations, optogenetics, calcium imaging, immunostaining, and connectomic analysis to provide convincing evidence of an inhibitory descending pathway that controls the switch from rolling to fast crawling behaviors of the larval escape response.

This fundamental work describes the complex interplay between light exposure, hypothalamic activity, and cognitive function. The evidence supporting the conclusion is compelling with potential therapeutic applications of light modulation. The work will be of broad interest to basic and clinical neuroscientists.

The authors report solid evidence for a valuable set of findings in rats performing a new virtual place-preference task. Temporary pharmacological inhibition targeting the dorsal or intermediate hippocampus disrupted navigation to a goal location in the task, and functional inhibition of the intermediate hippocampus was more detrimental than functional inhibition of the dorsal hippocampus. The work provides novel insights into functional differentiation along the dorsal-ventral axis of the hippocampus.
