Which part of the brain is involved in impulse control and is located right behind the eyes?

The orbitofrontal cortex is the correct choice because it plays a crucial role in impulse control, decision-making, and regulating emotions. This area of the brain is located in the frontal lobes, just above the orbits of the eyes, hence the name 'orbitofrontal.' The orbitofrontal cortex integrates sensory and emotional information, allowing individuals to evaluate choices and anticipate the consequences of their actions, which is essential for self-regulation and inhibiting impulsive behaviors.

The hippocampus is primarily associated with the formation of new memories and spatial navigation, rather than impulse control. The substantia nigra plays a significant role in reward, movement, and the regulation of mood, but it is not specifically tied to impulse control. The parahippocampal gyrus is more involved in memory encoding and retrieval, particularly related to spatial memory and context, rather than the regulation of impulses. Thus, the orbitofrontal cortex stands out as the key brain region responsible for impulse control.
