This is a fundamental work that significantly advances our understanding of the role of mossy cells in the dentate gyrus in Fragile X Syndrome. The carefully designed and executed extensive series of experiments provide compelling evidence that changes in their excitability occur due to up-regulation of Kv7 currents. The study unveils the underlying mechanisms of the disease, and therefore the work will be of interest to neuroscientists working on various aspects of Fragile X pathology. In addition, it also provides insights into how neuronal activity is balanced in networks through diverse cellular mechanisms.

This important study presents a detailed characterization of two distinct cellular morphologies of haematopoietic stem cells undergoing endothelial to haematopoietic transition in zebrafish. It brings new information on how regulation of apico-basal polarity influences cellular behaviour, shape, and interaction with neighbouring cells. The evidence supporting the existence of these two distinct morphologies is convincing, using state-of-the-art confocal microscopy and image analysis of 2D-cartography.

Understanding how genomic regulatory elements control spatiotemporal gene expression is essential for explaining cell type diversification, function, and the impact of genetic variation on disease. This important study provides solid evidence that enhancers generally combine additively to influence gene expression. Moreover, promoters, particularly weaker ones, can exhibit supra-additivity when integrating enhancer effects. These findings highlight the context-dependent nature of enhancer-promoter interactions in gene regulation, and contribute to ongoing discussions about the selectivity and combination of regulatory elements.

This study presents valuable findings on core genome mutations that might have driven the emergence of the Staphylococcus aureus lineage USA300, a frequent cause of community-acquired infections. The authors present a solid novel approach that combines genome-wide association studies and RNA-expression analyses, both applied to extensive publicly available datasets. This approach generated an intriguing hypothesis that should be validated experimentally. The work will interest microbiologists working in genomic epidemiology and phenotype-genotype association studies.

This study presents important insights into the dynamical process whereby sensory information is converted from stimulus-driven activity to a working memory representation from which the information can be recalled later. The evidence supporting the claims is convincing, using detailed fits and model-comparison techniques applied to new and existing psychophysical data sets to evaluate a wide variety of potential mechanisms. The overall conclusion, that iconic memory and working memory are not distinct mechanisms but rather two slightly different regimes of the same circuitry, will be of interest to neuroscientists and psychologists studying sensory systems and/or working memory.

This study provides valuable insights into the regulation of metabolic flux between glycolysis and respiration in yeast, particularly focusing on the role of inorganic phosphate. The authors propose a novel mechanism involving Ubp3/Ubp10 that potentially mitigates the Crabtree effect, offering substantial, solid evidence through a variety of well-designed assays. This study could reshape our understanding of metabolic regulation with broad biological contexts.

This important study discovered DBT as a novel gene implicated in the resistance to MG132-mediated cytotoxicity and potentially also in the pathogenesis of ALS and FTD, two fatal neurodegenerative diseases. The authors provided convincing evidence to support a mechanism by which loss of DBT suppresses MG132-mediated toxicity via promoting autophagy. This work will be of interest to cell biologists and biochemists, especially in the FTD/ALS field.

eLife assessment

This study reports that neural activity in the auditory cortex (field L) of singing male songbirds can be modulated by social context. These potentially important findings indicate that the presence of a female conspecific alters the response of auditory cortical neurons to the male bird's own song and to perturbations of auditory feedback that the bird has been trained to expect. While they extend recent work showing that the activity of dopaminergic neurons in songbirds is also affected by an audience, the evidence presented is incomplete since it is unclear how much of the apparent modulation of cortical neurons may be due to other factors, such as changes in the recorded neurons or their properties over time, which will require additional analyses to work out.

This manuscript describes valuable findings regarding the expression pattern of orexin receptors in the midbrain and how manipulating this system influences several behaviors, such as context-induced locomotor activity and exploration. The overall strength of evidence - which includes anatomical, viral manipulation studies, and brain imaging - is solid and broadly substantiates claims in the paper. However, there are several areas in which the conclusions are only partially supported by the combination of methods used. These results have implications for understanding the neural underpinnings of reward and will be of interest to neuroscientists and cognitive scientists with an interest in the neurobiology of reward.

This study presents important novel findings on how heterosynaptic plasticity can transform a weak associative memory into a stronger one, or produce a memory when stimuli were not paired. This work expands our views on the role of temporal- and input-specific plasticity in shaping learning and memory processes. The evidence, based on state-of-the-art in vivo manipulations, activity recordings, and behavioral analysis, is convincing. Findings will be of broad interest to neuroscience community, and especially those studying synaptic plasticity and associative memory.

This study enhances our understanding of the relationship between cortico-hippocampal interactions and behavioral performance. Using an inter-areal coherence metric to gate trial initiation in real time, the authors provide solid evidence that links high hippocampal-prefrontal theta coherence to correct performance on spatial working memory and cue-guided decision-making tasks. Although reviewers agreed that the results do not demonstrate causality between hippocampal-prefrontal synchrony and behavioral performance, the findings are viewed as important given their potential implications for brain-machine interface applications in humans.

This study presents useful findings from a large sample of participants from the UK Biobank on the relationship between menopause (including status, type, and age of onset), cognition, neuroanatomical measures derived from magnetic resonance imaging, and Alzheimer's disease. The strength of evidence is incomplete, and the study would benefit from clearer methodological descriptions, more careful consideration of potential confounds, and better theoretical integration with prior work in the field. This paper will be of interest to people working in the fields of cognitive neuroscience, endocrinology, and dementia.

This study reports important findings about pre-saccadic foveal prediction and the extent to which it is influenced by the visibility of the saccade target relative to its background. The research methodology and results make a convincing case that foveal congruency effects develop when salient local contrast variations at the saccade target location can be used to direct the eye movement. This work should be of broad interest to visual neuroscientists, as well as those interested in understanding perception in the context of eye movements and in modeling visually guided actions.

In this study, the authors develop a strategy for fluorophore-tagging endogenous proteins in human induced pluripotent stem cells (iPSCs) using a split mNeonGreen approach, and they conclude that the system will be appropriate for performing live imaging studies of highly dynamic cellular processes such as cytokinesis in iPSCs. Experimentally, the methods are solid, and the data presented support the authors' conclusions. Overall, these methodologies should be useful to a wide audience of cell biologists who want to study protein localization and dynamics at endogenous levels in iPSCs.

This fundamental study provides an unprecedented understanding of the roles of different combinations of NaV channel isoforms in nociceptors' excitability, with relevance for the design of better strategies targeting NaV channels to treat pain. Although the experimental combination of electrophysiological, modeling, imaging, molecular biology, and behavioral data is convincing and supports the major claims of the work, some results remain inconclusive and need to be strengthened by further evidence. The work may be of broad interest to scientists working on pain, drug development, neuronal excitability, and ion channels.
