Frontal Control of the Limbic System

What role does the orbital frontal region play?

The orbital frontal region lies on the underside of the frontal lobe, just above the eyes. This brain region is particularly important for impulse control, for the inhibition of dangerous or reckless actions. People with damage to their orbital frontal cortex show disinhibited, impulsive, and socially unacceptable behavior. The case of Phineas Gage is a famous example of orbital frontal damage. Orbital frontal inhibition probably works through linking representations of future events with representations of past or future punishment.
