Context examples:
Increasing levels of BDNF in the ventromedial portion of the prefrontal cortex, a brain region involved in compulsive drug and alcohol seeking, returned the mice to moderate levels of alcohol intake.

In the brain, MRs are mainly located in the amygdala and the prefrontal cortex — two key brain areas involved in the development and maintenance of AUD.

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.

These findings suggest that seizures may alter how the prefrontal cortex responds to hippocampal activity and thus interfere with normal memory consolidation.

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.

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.

This pattern involved what scientists described as neuroflexibility, in a circuit between the brain’s medial prefrontal cortex and forebrain regions including the ventral striatum, extended amygdala, and hippocampus during sustained stress exposure.
