Longitudinal Changes in Cortical Response Dynamics with Deep Brain Stimulation to the Subcallosal Cingulate for Treatment-Resistant Depression

Aashna Desai, Tine Van Bogaert, Ki Sueng Choi, Ha Neul Song, Jungho Cha, Sankaraleengam Alagapan, Elisa Xu, Jacob Francis Dahill-Fuchel, Ashan Veerakumar, Brian Harris Kopell, Martijn Figee, Patricio Riva‐Posse, Christopher J. Rozell, Helen S. Mayberg, Allison C. Waters

This study tracks changes in cortical response dynamics during SCC-DBS for treatment-resistant depression, finding reduced latency and increased magnitude of stimulation-evoked potentials over time.
