Thalamus and ocd
WebThese structures provide inhibitory tone to the thalamus, mediated by a balance of “accelerator- brake” activity through the direct and indirect pathways. 10 An imbalance in this system with increased activity in the direct pathway, would disinhibit the thalamus and promote repetitive behavioral sequences. 11 The most accepted model of pathogenesis … WebAim Although the thalamus is a key structure in the pathophysiology of obsessive-compulsive disorder (OCD), reports regarding thalamic volume alterations in OCD patients …
