  eLife Assessment

  This study provides important insights into how working memory shapes perceptual decisions, using a dual-task design, continuous mouse tracking, and hierarchical Bayesian modeling. By dissociating fast attentional capture effects from slower, sustained perceptual biases within single trials, the authors provide compelling evidence that working memory-perception interactions unfold through distinct dynamic processes rather than a single mechanism. This work will be of interest to researchers studying working memory, perception, decision-making, and mouse-tracking methodology.

  This fundamental work advances our understanding of the role of human hippocampal theta oscillations in memory encoding and retrieval. The evidence supporting the conclusions is convincing, using both scopolamine administration and intracranial EEG recordings. This work will be of broad interest to neuroscientists and has translational implications.

  eLife Assessment

  This valuable study demonstrates molecular changes associated with age related impairment in oligodendrocyte differentiation and ability to myelinate. The identification of particular genes that are associated with this decline will provide potential future targets for therapeutic interventions. The reviewers felt that the quality of the evidence was solid while identifying some minor weaknesses that if addressed would enhance the rigor of the study.

Ventral Hippocampal Temporoammonic and Schaffer Collateral Pathways Differentially Control Fear- and Anxiety-Related Behaviors

  Kambali et al use optogenetic manipulations to examine whether the ventral hippocampal Schaffer collateral (vCA3-to-vCA1) and temporoammonic (EC-to-vCA1) pathways regulate anxiety- and fear-related behaviors in mice. They find that both pathways regulate the expression of fear (freezing) responses to a context and auditory conditioned stimulus paired with foot shock (trace conditioning protocol), but only the Schaffer collateral pathway regulates the expression of anxiety-related behaviors in the elevated plus maze, open field test, and Vogel conflict test. Overall, the study is valuable: it detects bidirectional effects of optogenetic excitation and inhibition in both pathways. However, the strength of the evidence in support of its main claims is incomplete.
