پاسخ لیمبیک به استرس روانی- اجتماعی در اسکیزوتایپی: یک مطالعه تصویربرداری رزونانس مغناطیسی عملکردی

All three groups showed significant increases in self-reported stress and significant fMRI signal change in the striatal, limbic and cortical regions. However, the Physical Anhedonia group showed greater stress-induced striatal and limbic deactivation than the other two groups. Deactivation in the striatum was significantly correlated with Physical Anhedonia score across all subjects. Our findings suggest the presence of abnormalities in striatal response to stress in negative symptom schizotypy.
