     This valuable paper reports on a measure of flexible brain state engagement, derived from fMRI, as a predictor of cognitive control. One strength of the study is the use of external datasets for validation and replication. The results are solid, although some may benefit from further explanation.

     This valuable study aimed to explore whether sensory representations in the cortex reorganize on the same timescale over which behavioral changes first emerge. Convincing evidence is presented to show that reward-dependent plasticity takes place in the mouse barrel cortex within a single recording session as mice learn a whisker detection task. However, the evidence supporting the authors' proposal that this rapid reorganization may involve spontaneous reactivation of neurons that gain stimulus responsiveness during training is incomplete. The work will be of interest to systems neuroscientists studying cortical circuits and learning.

     This valuable study describes a simple and robust approach for estimating information-limiting noise by splitting neural populations and comparing estimator values. The authors report more accurate and robust results compared to previous methods. The evidence for the robustness of the method is currently incomplete; some concerns regarding bias need to be resolved, and additional tests need to be provided on how the number of trials and neurons affect performance.

     This work establishes a valuable theoretical finding about how the spike timing dependence of inhibitory plasticity shapes recurrent network connectivity. The combination of theoretical analysis and simulations provides convincing evidence that effective inhibitory connectivity forms a so-called Mexican-hat profile when multiple inhibitory neuron types follow distinct learning rules. These mechanisms are thought to be implicated in the contextual modulation of neuronal responses to stimuli.

     This valuable study establishes a novel genetic model for chronic, in vivo visualization of protein engulfment in brain macrophages from the naturally short-lived African turquoise killifish. The solid data presented here show that brain phagocytes exhibit transcriptional features resembling mammalian border associated macrophages and monocyte derived macrophages rather than classical microglia and that their engulfment capacity declines with age, providing a resource for future studies on brain immune cells in teleosts. This research will interest a broad audience across developmental biology, genetics, neuroimmunology, aging research, and evolutionary biology.

     This valuable descriptive study describes the expression of a developmentally relevant transcription factor in the adult Tribolium brain. The evidence supporting the claims is convincing and based on a very detailed and rigorous analysis of light microscopy data, which, however, lacks single-cell resolution. This neuroanatomical study is of interest to the field of insect neural development and neuroscience.

     This paper describes a valuable tool for the detection and analysis of dentate spikes, network events in the dentate gyrus that are common yet understudied. This tool could help standardize dentate spike detection and analysis across labs and is therefore likely to be of interest to hippocampal neurophysiologists. However, the strength of evidence for its broad usefulness was viewed as incomplete, due to several identified bugs in the program and insufficient explanations of parameter selection and methods.

     This set of studies provides important knowledge for the role of zona incerta neurons in motivation and food-seeking in mice. The evidence supporting the findings is convincing, with the use of multiple approaches and nice behavioral procedures to provide converging lines of evidence. Additional analyses and data from the current studies would further strengthen the evidence. This work will be of interest to those interested in motivation and its brain substrates.

     This study demonstrates a critical role of the glycolipid membrane protein insertase (MPIase) in the twin-arginine translocation (Tat) pathway, a protein translocation system that is conserved across all domains of life. The successful reconstitution of the bacterial Tat system in both bacteria-derived and artificial liposomes provides solid experimental evidence that MPIase has a broader role in membrane protein translocation than previously recognized. By revealing the essential function of a nonproteinaceous membrane component in catalyzing a core cellular process, this work offers fundamental insights into the molecular mechanisms of protein translocation.

      The authors provide convincing evidence that, during early mouse embryogenesis, distal visceral endoderm cells migrate in a coordinated, intermittent start-and-stop manner along an axis that correlates with the asymmetric morphology of the ectoplacental cone. This fundamental finding is supported by high-quality live imaging and quantitative image analysis, while computational modelling suggests that the observed intermittent behavior may be explained by the movement of a cohesive cell group through a viscoelastic tissue, rather than by fluctuations in DVE migration velocity itself.
