Abstract The pathophysiology of depression involves multiple biological processes, including circuit dysfunction and impaired neuroplasticity, yet an integrative view linking these processes remains elusive. Here, we identify a convergent circuit for antidepressant response and plasticity modulation. We demonstrate that chemogenetic activation of the infralimbic cortex (IL) exerts rapid antidepressant-like effects across multiple behavioral domains in a mouse model of stress-induced depression.

The dentate gyrus efficiently converges LEC and MEC inputs into multimodal, highly specific and reliable environmental representations

Abstract The entorhinal cortex–hippocampal network plays a key role in the processing, storage and retrieval of contextual information. However, how convergent multimodal information provided by the lateral and medial entorhinal cortex (LEC and MEC) is represented by granule cells (GCs), the principal cells of the dentate gyrus (DG), remains poorly understood.
