Clinical Trial Summary

Investigating whether delta-beta cross-frequency transcranial alternating current stimulation can increase goal-directed behavior in participants with major depressive disorder and elevated symptoms of anhedonia.


Clinical Trial Description

The purpose of this clinical trial is to investigate the causal role that delta-beta coupling plays in goal-directed behavior in participants with major depressive disorder (MDD) and symptoms of anhedonia. The participants will perform a reward-based decision-making task. During the task, cross-frequency transcranial alternating current stimulation (tACS) will be delivered at delta-beta frequency, a control-frequency, or an active sham. Electroencephalography will be collected in intermittent resting-state periods. Structural and functional magnetic resonance imaging (MRI) will be collected during the resting-state and during performance of the task. ;
