WebOct 15, 2016 · As one of the brain imaging techniques, voxel-based morphometry (VBM) has been widely used in OCD research since it was introduced in 2000 [5]. Although all the studies focused on the structural changes of the brain regions involving the CSTC circuits, the findings are inconsistent. WebThe cortico-basal ganglia-thalamo-cortical loop ( CBGTC loop) is a system of neural circuits in the brain. The loop involves connections between the cortex, the basal ganglia, …

WebMay 18, 2024 · Notably, most of the activated brain regions were related to the CSTC loop elements corresponding to the postulated CSTC loop dysfunction in OCD. In mice and rats, the 5-HT receptor 2C (5-HT2C) is mainly distributed in the choroid plexus and other areas, including the nucleus accumbens, patches of the caudate-putamen, ... WebThe CSTC circuits play a critical role in the neurobiology of OCD. These circuits involve connections between the cortex (the outer layer of the brain), the striatum (a subcortical structure involved in movement and reward), the thalamus (a relay center for sensory information), and back to the cortex. how to select multiple lines at once

WebFeb 7, 2024 · Several studies show that DBS is capable of normalizing brain activity in main CSTC brain circuits, likely by targeting CSTC white matter tracts connecting frontal and thalamic and/or striatal regions. This potentially disturbs aberrant signaling and restores the capacity for physiological CSTC communication. Importantly, evidence suggests that ...
