     Pak et al. examined the relationship between the most common spatial patterns of neurodegeneration and transcriptional markers of the density of different cell types in the cerebral cortex. This valuable study uses innovative methods to provide convincing evidence that patterns of grey matter loss in various forms of dementia are correlated with the anatomical distribution of non-neuronal cell types.

     This fundamental study substantially advances our understanding of the role of zinc in metabolism, specifically a newly established clinical link between mutations in the zinc transporter SLC39A5, elevated serum zinc levels, and a reduction in the risk of Type 2 Diabetes. The provided evidence is solid with state-of-the-art genetic analysis of large human cohorts followed by a comprehensive analysis of a mouse SLC39A5 knockout mutant, establishing that SLC39A5 plays a role in hepatic lipid handling through AMPK signaling, although the limited analysis of a pancreatic phenotype that has previously been described constitutes a weakness. This study will be of relevance to researchers interested in metabolism, fatty liver disease, and the biology of trace elements.

     This valuable study advances our knowledge of the effects of anxiety/depression treatment on metacognition, demonstrating that treatment increases metacognitive confidence alongside improving symptoms. The authors provide convincing evidence for the state-dependency of metacognitive confidence, based on a large longitudinal treatment dataset. However, it is unclear to what extent this effect is truly specific to treatment, as changes in metacognitive confidence in the group receiving online therapy were not statistically different from those in the control group.

     This important study used Voltage Sensitive Dye Imaging (VSDI) to measure neural activity in the primary visual cortex of monkeys trained to detect an oriented grating target that was presented either alone or against an oriented mask. The authors show convincingly that the initial effect of the mask ran counter to the behavioral effects of the mask, a pattern that reversed in the latter phase of the response. They interpret these results in terms of influences from the receptive field center, and although an alternative view that emphasizes the role of the receptive field surround also seems reasonable, this study stands as an interesting contribution to our understanding of mechanisms of visual perception.

     In this fundamental work, the authors demonstrated that maternal choline supplementation improved spatial memory, reduced hyperexcitability, and restored NeuN expression in a familial Alzheimer's disease mouse model. Interestingly, choline deficiency increased mortality, while paradoxically reduced hyperexcitability. Through behavioral, electrophysiological, and histological measures, the authors present convincing evidence supporting the significant role of maternal choline supplementation in protecting hippocampal functions vulnerable to Alzheimer's disease.

     In this paper, the authors introduce fundamental work on mathematical methods for inferring evolutionary parameters of interest from RNA data in healthy tissue and during hematopoiesis. By combining single cell and bulk sequencing analyses, the authors use a stochastic process to inform different aspects of genetic heterogeneity; the strength of evidence in support of the authors' claim is exceptional. The work will be of broad interest to cell biologists and theoretical biologists.

     This important manuscript investigates the role of a subpopulation of glutamatergic neurons in the suprammamillary nucleus that projects to the pre-optic hypothalamus area in active coping but not locomotor activity. They provide solid evidence from experiments using fibre photometry or photostimulation during threatening tasks that these neurons allow animals to produce flexible behaviours in response to stress. This work will be of interest to behavioural and systems neuroscientists.

     This important study advances our understanding of how listeners understand speech when there are multiple talkers by showing that the content of the speech affects acoustic processing. The evidence is generally solid, although additional details on the methods to allow replication would strengthen the study. The work will be of use to researchers interested in the neuroscience of speech and language processing.

     This important study identifies a spatial pattern of neural activity that corresponds to trust in an investment game. It provides a compelling assessment of the validity of this pattern by assessing its expression, or lack thereof, in a variety of datasets. This work, and the "neurometrics" approach it proposes, will be of broad interest to psychology researchers more generally.

      This is an important study that improves gene models for the ferret genome and identifies neural progenitors that are comparable to those found in developing human brains. The data are convincing and clearly presented. Of particular interest to the field, the work identifies enriched expression of FOXJ1 in late truncated radial glia, strongly indicating that towards the end of neurogenesis, these cells likely give rise to ependymal cells. The work is of interest to anyone studying the development of the nervous system, especially colleagues studying the evolution of development.
