Abnormal affect in OCD has been hypothesized to result from dysfunction in the OFC, ventral striatum, and amygdala. (wikipedia.org)
This is reflected by reduced amygdala and ventral striatum response to positive stimuli, and elevated amygdala response to fearful stimuli. (wikipedia.org)
The ventral striatum is important in action selection, and receives inputs from the medial OFC that signal various aspects of value for stimulus association outcomes. (wikipedia.org)
By assigning abnormal values to certain behaviors, OFC may lead to compulsive behavior through modulating action selection in the ventral striatum. (wikipedia.org)
Putamen3
8] During affective tasks hyperactivation has been observed in the ACC, insula and head of the caudate and putamen, regions implicated in salience, arousal, and habit. (wikipedia.org)
La sustancia gris constituye el NÚCLEO CAUDADO y el núcleo lenticular (este último derivado de la unión del GLOBO PÁLIDO y el PUTAMEN). (bvsalud.org)
The gray substance is made up of the CAUDATE NUCLEUS and the lentiform nucleus (the latter consisting of the GLOBUS PALLIDUS and PUTAMEN). (bvsalud.org)
Lateral3
These fibers run between the most lateral segment of the lentiform nucleus and the claustrum. (stickycompany.com)
The part of the hypothalamus posterior to the middle region consisting of several nuclei including the medial mamillary nucleus, lateral mamillary nucleus, and posterior hypothalamic nucleus (posterior hypothalamic area). (nih.gov)
It contains the lateral hypothalamic nucleus, tuberomammillary nucleus, lateral tuberal nuclei, and fibers of the medial forebrain bundle. (nih.gov)
