Increased activity in these areas occurred in concert with activity in the inferior frontal junction, an area of the prefrontal cortex that controls visual processing areas.

Already in 2015, the same research group published a meta-study in the journal Intelligence, in which they identified brain regions — among them the prefrontal cortex — activation changes of which are reliably associated with individual differences in intelligence.

The new research shows that OCD is also linked to medial prefrontal cortex abnormality.

The researchers found that levels of 103 miRNAs were different in the amygdala and 31 in the prefrontal cortex of mice reared without gut bacteria (GF mice) compared to conventional mice.

The authors note that previous research has consistently shown that repeated and chronic stress damages the structure, connections, and functions of the brain’s prefrontal cortex.

The researchers found that hippocampal IEDs were followed by spindles in the prefrontal cortex.

Along the midline of the frontal lobe, where the left and right brain hemispheres meet, there is a wall of neural tissue known as the medial prefrontal cortex.

These scans showed that neural activity patterns in another brain region, the prefrontal cortex, distinguished between categories and that subjects used that information to make their judgments.

The prefrontal cortex area of the brain oversees important functions such as judgment, decision making, and problem solving, as well as emotional control and memory.

In AUD, amygdala dysfunction heightens activation of brain stress systems resulting in anxiety and other negative emotions, while disruption of the prefrontal cortex impairs executive control systems involved in the ability to make decisions and regulate one’s actions, emotions, and impulses.
