From: An fMRI study of unconditioned responses in post-traumatic stress disorder
Increased putamen unconditioned stimulus (US) responses in subjects with post-traumatic stress disorder (PTSD). US responses in PTSD minus trauma-exposed non-PTSD control (TENC) displayed at T > 4 on a template magnetic resonance imaging (MRI) scan. The bilateral putamen displayed the most prominent hyperactivation in PTSD, no region displayed hypoactivation in PTSD.
