This study shows that grooming increases after stress when danger is absent, indicating it reflects post-stress recovery rather than a defensive response.

This study examines how hippocampal and medial entorhinal circuit dysfunction evolves with cognitive deficits in epilepsy using in vivo electrophysiology in mice.

This study identifies an anterior hypothalamic circuit that modulates stress vulnerability by integrating valence signals from the amygdala.

The paper investigates how stress-induced plasticity in the amygdala and ventral hippocampus differentially supports non-associative defensive behaviors.

This paper introduces a dual-channel miniscope for simultaneous two-wavelength calcium imaging in freely behaving mice, showing spatial coding changes over time.

This study shows that strong aversive experiences in mice drive offline reactivation of both recent aversive and older neutral memories, linking them across days.

This study identifies a mechanism where hippocampal ensembles are remodeled to support memory-updating in mice during spatial reversal tasks.

Minian is an open-source pipeline for analyzing single-photon in vivo calcium imaging data, offering low memory usage, interactive visualizations, and parameter exploration tools.

This study investigates the role of the mOFC-BLA circuit in reward-related decision making in rats, finding distinct functions for bidirectional connections in processing reward cues and their desirability.

This study identifies a PACAPergic microcircuit in the amygdala that modulates contextual fear in a sex-dependent manner, with distinct effects on fear acquisition, generalization, and extinction.

ezTrack provides an open-source video analysis pipeline for animal behavior studies, offering tools for tracking and freezing behavior analysis without requiring programming expertise.
