This paper reports a valuable new method for creating localized damage to candidate brain regions for functional and behavioral studies. The authors present solid support for their ability to create long-term local lesions with mm spatial resolution. The paper is likely to be of broad interest to brain researchers working to establish causal links between neural circuits and behavior.

This valuable study uses a novel experimental design to elegantly demonstrate how we exploit stimulus structure to overcome working memory capacity limits. The presented behavioural and neural evidence are solid and in line with the proposed information compression mechanism. This study will be of interest to cognitive neuroscientists studying structure learning and memory.

This study presents an important finding on the function of PLP1+ enteric glia. The evidence supporting the claims of the authors is solid, although the inclusion of additional data showing the mechanisms by which PLP1+ enteric glia acts on Paneth cells would have strengthened the study. The work will be of interest to researchers working on intestinal biology.

eLife assessment

This valuable study presents the design of a new device to use high-density electrophysiological probes ("Neuropixels") in freely moving rodents. The evidence showing that the system is versatile and capable of recording high-quality extracellular data in both mice and rats is compelling. This study will be of interest to neuroscientists performing chronic electrophysiological recordings.

The authors report that optogenetic inhibition of hippocampal axon terminals in retrosplenial cortex impairs the performance of a delayed non-match to place task. Elucidating the role of hippocampal projections to the retrosplenial cortex in memory and decision-making behaviors is important. However, the strength of evidence for the paper's claims is incomplete.

This important study provides insights into how the brain constructs categorical neural representations during a difficult auditory target detection task. Through recordings of simultaneous single-unit activity in primary and secondary auditory areas, compelling evidence is provided that categorical neural representations emerge in a secondary auditory area, i.e., PEG. The study is of interest to neuroscientists and can also potentially shed light on human psychological studies.

This manuscript presents experiments that address the question of whether the lateral parafacial area (pFL) is active in controlling active expiration, which is particularly significant in patient populations that rely on active exhalation to maintain breathing (eg, COPD, ALS, muscular dystrophy). This study presents solid evidence for a valuable finding of pharmacological mapping of the core medullary region that contributes to active expiration and addresses the question of where these regions lie anatomically. Results from these experiments will be of value to those interested in the neural control of breathing and other neuroscientists as a framework for how to perform pharmacological mapping experiments in the future.

This study presents an important finding on the influence of visual uncertainty and Bayesian cue combination on implicit motor adaptation in young healthy participants, hereby linking perception and action during implicit adaptation. The evidence supporting the claims of the authors is convincing. The normative approach of the proposed PEA model, which combines ideas from separate lines of research, including vision research and motor learning, opens avenues for future developments. This work will be of interest to researchers in sensory cue integration and motor learning.

eLife assessment

This fundamental study investigates the transcriptional changes in neurons that underlie loss of learning and memory with age in C. elegans, and how cognition is maintained in insulin/IGF-1-like signaling mutants. The presented evidence is compelling, utilizing a cutting-edge method to isolate neurons from worms for genomics that is clearly conveyed with a rigorous experimental approach. Overall, this study supports that older daf-2 worms maintain cognitive function via mechanisms that are unique from younger wild type worms, which will be of great interest to neuroscientists and researchers studying ageing.

eLife assessment

This computational modeling study builds on multiple previous lines of experimental and theoretical research to investigate how a single neuron can solve a nonlinear pattern classification task. The study presents valuable insights that the location of synapses on dendritic branches, as well as synaptic plasticity of excitatory and inhibitory synapses, influences the ability of a neuron to discriminate combinations of sensory stimuli. However, the evidence presented is incomplete - the major conclusions are only partially supported by the data presented, and there are identified gaps between the supporting evidence and the major conclusions.
