amygdala and the VmPFC
that, as discussed in more detail shortly, are
When frequent news readers thought about whether to share the article, there were high levels of connection between the vmPFC
and a region of the brain that supports the ability to exert deliberate control over your thoughts and feelings.
The results revealed a clear role for the vmPFC
in encoding an expected reward before all information had been revealed.
The Iowa Gambling Task (IGT) revealed significantly more mistakes in decision making associated with the dysfunction of vmPFC
in binge drinkers, as well as the overactivation of the insula bilaterally .
More specifically, Damasio (1994) postulated that the VMPFC
plays a key role in the production of somatic markers which are responsible for emotional reactions associated with prediction of long-term outcomes of specific responses in given situations or contexts.

For an additional example, see id, for the story of JZ, another patient for whom the removal of part of his VMPFC
caused a disturbance in his social decisionmaking faculties.
In effect, there seems to be an inverse correlation between vmPFC
and dACC activity .
A significant group (MORE, control) x time (Pre, Post) interaction in left ventral striatum (VS: -14,16, -15) and right vmPFC
(10, 20, -10).

Focusing attention on the health aspects of foods changes value signals in vmPFC
and improves dietary choice.
