Assessing accelerometry as an alternative to electromyography for mouse sleep scoring

This study evaluates the agreement between electromyography (EMG) and accelerometry (Acc) for sleep scoring in mice, finding high overall accuracy but some bias in Wake and NREM classification.

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.

Curved flexible neural interfaces for laminar electrophysiology in deep-brain structures

This paper introduces a curved flexible neural interface for laminar electrophysiology in deep-brain structures, demonstrating stable recordings in the ventral hippocampus over four weeks.

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.

Parallel streams of raphe VGLUT3-positive inputs target the dorsal and ventral hippocampus in each hemisphere.

The paper maps VGLUT3-positive projections from the raphe nuclei to the hippocampus, revealing two distinct streams targeting dorsal and ventral regions.
