Ketamine is increasingly used as a therapeutic option for treatment-resistant depression (TRD) due to its rapid antidepressant properties; however, the mechanisms underlying these effects remain elusive. Preclinical evidence suggests ketamine acts on neural pathways implicated in reward processing, but translational efforts have proven challenging due to a lack of paradigms allowing for...
Treatment-resistant depression (TRD) accounts for approximately 30% of major depressive disorder cases and has been characterized by altered functional connectivity within and between the Default Mode (DMN) and Frontoparietal networks (FPN). Ketamine can be an effective treatment for TRD, and its antidepressant response has been associated with alterations in resting state functional...
