Fig. 4: Functionality of ventro-medial STN theta activity in OCD vs PD patients.
From: Subthalamic theta activity: a novel human subcortical biomarker for obsessive compulsive disorder
Patients were tested in four tasks a while STN activity was recorded: OCD provocative images task (neutral, aversive, and OCD provocative images); doubt task (positive, negative, and ambiguous cues); Go-NoGo task (hit, correct rejection (CR), and commission error (CE)); emotional voices task (positive, neutral, and negative voices). b Average ventro-medial STN theta power during tasks events. Shadows represent standard error of the mean. Time zero indicates trial beginning; black horizontal lines indicate time for statistical analysis. In the Go-NoGo task (third row) vertical lines indicate response time in hit (green) and CE (red) trials. c Average theta power during time selected for statistical comparison. Error bars represent standard error of the mean. *p < 0.05, **p < 0.01, ***p < 0.001
