The prefrontal cortex is the brain region primarily involved in complex cognitive behavior and decision-making. This area of the brain is located at the front of the frontal lobe and is critical for various high-level functions, including decision-making, problem-solving, planning, and social behavior. It integrates information from various parts of the brain, allowing individuals to weigh potential outcomes and make judgments based on previous experiences and anticipated consequences.

The prefrontal cortex also plays a significant role in executive functions, which include attention control, impulse regulation, and reasoning. These processes are essential for navigating complex social interactions and making informed decisions that align with long-term goals rather than immediate desires.

In contrast, the cerebellum is primarily involved in the coordination of movement and balance rather than cognitive processes. The hippocampus is key for memory formation and spatial navigation, and while it contributes to the memory aspects of decision-making, it does not handle the complex socio-cognitive elements. The brainstem is involved in basic life functions such as heart rate and breathing, rather than complex behaviors and decision-making processes.
