Anatomical organization and origins of VGLUT3-positive axon terminals in the lateral septum.

This study maps the anatomical organization and origins of VGLUT3-positive axon terminals in the lateral septum, identifying multiple sources beyond the raphe nuclei.

Hyperexcitability of female serotonin neurons underlies sex-specific anxiety responses

This study identifies a hyperexcitable serotonergic pathway from the median raphe region to the ventral hippocampus that drives sex-specific anxiety responses in mice.

A population code for idiothetic representations in the hippocampal-septal circuit

The paper develops an unsupervised model to decode elapsed time and distance from neural activity in freely moving mice, showing spatiotemporal information is a mix of idiothetic and allocentric signals.

Optogenetic frequency scrambling of hippocampal theta oscillations dissociates working memory retrieval from hippocampal spatiotemporal codes

This study uses optogenetics to disrupt theta rhythms in mice and shows that theta is essential for working memory retrieval but not for spatiotemporal coding.

Conjunctive spatial and idiothetic codes are topographically organized in the GABAergic cells of the lateral septum

The paper identifies spatial and idiothetic coding in LS GABAergic cells, showing topographic organization and functional connectivity with hippocampal regions.
