  This study provides a valuable insight into how the medial and lateral entorhinal cortices interact through distinct excitatory and inhibitory pathways. Using anatomical tracing, optogenetics, and electrophysiology, the authors show that glutamatergic medial entorhinal neurons provide broad excitatory input to lateral entorhinal, while long-range SST+ interneurons deliver selective inhibition to layer I. These findings reveal a novel layer- and cell-type-specific organization of medial to lateral entorhinal connectivity with implications for spatial and episodic memory. The work is solid, but validation of injection specificity and viral spread is needed to fully confirm the anatomical interpretations; with these clarifications, this will be a significant contribution to understanding entorhinal-hippocampal circuit organization.

  This important study provides novel evidence that navigational experiences can shape perceptual scene representations. The evidence presented is incomplete and would benefit from clearer explanations of the experiment design and careful discussion of alternative interpretations such as contextual associations or familiarity. The work will be of interest to cognitive psychologists and neuroscientists working on perception and navigation.

Dorsal hippocampus mediates light–tone associations in male mice

  Pinho et al use in vivo calcium imaging and chemogenetic approaches to examine the involvement of hippocampal sub-regions across the different stages of a sensory preconditioning task in mice. They find evidence for sensory preconditioning in male mice. They also find that, in these mice, CaMKII-positive neurons in the dorsal hippocampus encode the audio-visual association that forms in stage 1 of the task. The evidence in support of these findings is convincing. The important study will be of interest to researchers in the fields of learning and memory and/or hippocampus function.

  This paper provides potentially valuable insight into why memory consolidation may differ between children (5-7 years of age) and adults. The work hints at developmental differences in neural engagement during the retrieval of recent and remote memories. However, there are several major concerns with the analyses not alleviated by included controls, and as such the evidence supporting the authors' main claims remains incomplete.

  This important study demonstrates that some degree of spatial tuning (e.g., place cells) and ability to decode spatial location emerges in sufficiently complex systems trained to process visual information. This intriguing observation challenges existing approaches and findings used in the study of spatial navigation. However, the strength of evidence regarding the nature and quality of spatial tuning, its compatibility with experimental data, and the overall interpretation of the study remains incomplete. This work will be of interest to the research community of spatial navigation.

  This valuable manuscript provides solid evidence regarding the role of alpha oscillations in sensory gain control. The authors use an attention-cuing task in an initial EEG study followed by a separate MEG replication study to demonstrate that whilst (occipital) alpha oscillations are increased when anticipating an auditory target, so is visual responsiveness as assessed with frequency tagging. The findings offer a re-interpretation of the inhibitory role of the alpha rhythm, supporting that alpha oscillations contribute to interareal communication.

• Curated by eLife

  The authors used a Bayesian modeling framework to fit behavior and serotonin neuron activity to reward history across multiple timescales. A key goal was to distinguish value coding from other influences, particularly thirst, by comparing model fits across neurons. Although the question and approach are valuable, several limitations of the current manuscript mean that support for the conclusions is incomplete.
