Fig. 2: Post-operative recordings of beta and theta activity in dorso-lateral and ventro-medial STN in OCD and PD patients.
From: Subthalamic theta activity: a novel human subcortical biomarker for obsessive compulsive disorder
a, b Average PSD (N = 52) of post-operative recordings of one OCD patient (Same patient as in Fig. 1), arranged spatially (a) and in a spectrogram (b). c, d Average spectral activity from dorsal (c; bipolar pairs: E2–E3 and E10–E11) and ventral (d; bipolar pairs: E0–E2 and E8–E10) STN of OCD and PD (on and off medication) patients in five recording sessions from one week to three months post operation. Gray areas indicate frequencies in which the difference between the groups is significant (p < 0.05 after Bonferroni correction)
