From: Basal ganglia dysfunction in OCD: subthalamic neuronal activity correlates with symptoms severity and predicts high-frequency stimulation efficacy

Figure 1

Distribution of oscillatory activity of subthalamic neurons recorded in obsessive–compulsive disorder (OCD) and Parkinson's disease (PD) patients. (a) Relative proportion of the 138 and 173 subthalamic nucleus (STN) neurons showing oscillatory activity in OCD and PD patients. Asterisks indicate significant differences (P<0.05) between neurons of OCD and PD patients. (b) Subthalamic oscillatory activity as a function of subthalamic subdivisions in OCD and PD patients. Top histogram: relative proportion of neurons recorded in the sensorimotor (SM), associative (AS) and limbic (LI) subdivisions and showing none, one or more than one period of significant oscillatory activity. Bottom histogram: relative proportion of neurons recorded in the SM, AS and LI subdivisions and showing significant oscillatory activity in the θ, α, β-low, β-high and γ band frequencies.
