Final answer:
Gerard's frequent involvement in fist fights may suggest dysfunction in the frontal lobes of the brain, which are responsible for impulse control and emotional regulation.
Step-by-step explanation:
The area of Gerard's brain that is likely not functioning at its highest level is the frontal lobes. The frontal lobes are responsible for controlling impulsive behavior, decision-making, and regulating emotions. If Gerard frequently gets into fist fights, it suggests that he may have difficulties with impulse control and emotional regulation, which can be attributed to dysfunction in the frontal lobes. Dysfunction in this area can also be associated with poor judgment and risky behavior.
