Abstract

Drug evoked synaptic plasticity represents “memory traces” in the brain following abuse experiences. Preclinical studies have detailed the myriad changes in mesolimbic and cortical functioning, including alterations in synaptic transmission and plasticity. In humans, recent research advances utilizing a combination of non-invasive brain stimulation and neurophysiological readouts have opened a new avenue for the study cortical plasticity in clinical substance dependence states. These insights, along with findings in psychopathology more generally, uniquely positions brain stimulation as a key tool for understanding cortical function and plasticity in substance dependence.
