They found that several brain regions of Patients with OCD showed above normal levels of activation during the relatively easy non-interference section of the color and word matching task (including the left parahippocampal gyrus, paracentral lobule, thalamus, and calcarine gyrus) and only a few regions showed lower levels of activation than controls (the anterior cingulate and left caudate nucleus); however, during the more difficult matching task when interference was present there were no brain regions in Patients with OCD with higher than normal activation and some brain regions showed lower than normal activation (e.g., bilateral orbital prefrontal cortex
, left anterior cingulum and left caudate nucleus).
All the patients had impairment in the dorsolateral prefrontal cortex, the orbital prefrontal cortex
or the anterior cingulate cortex.
Summary: TEHRAN (FNA)- Researchers suggested that there is a link between the number of friends you have and the size of the region of the brain - known as the orbital prefrontal cortex
- that is found just above the eyes.
Compared to a healthy SPECT scan, J's scan (Figure 3) showed low activity in the inferior orbital prefrontal cortex
, an area of the brain involved with impulse control.
The anterior cingulate cortex, orbital prefrontal cortex
, and dorsolateral prefrontal cortex "are cortical regions you need to know about," Dr.
Mayberg and her colleagues looked at their data again and found that in both groups, patients who eventually got better had increased metabolic activity after 1 week in the ventral striatum and orbital prefrontal cortex
