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...
