  This study investigates how people adapt their speech when auditory feedback is altered. The analyses are rigorous and the work makes a valuable contribution by extending methods from limb motor control to speech. However, because the paradigm does not directly measure sensory error, the evidence for the proposed mechanism of sensorimotor learning is incomplete. The findings are best viewed as evidence for how prior motor adjustments influence subsequent behaviour, highlighting the need for future studies to more precisely separate sensory and motor contributions to adaptation.

  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.
