The prefrontal cortex is a part of the brain located at the front of the frontal lobe. It plays a crucial role in complex cognitive behaviors, decision-making, and social interactions. This area is responsible for functions such as planning, reasoning, and impulse control, helping individuals manage their thoughts and actions effectively. Additionally, the prefrontal cortex is involved in regulating emotions and understanding social cues. It helps in forming judgments and predicting the consequences of actions, making it essential for personal and social functioning. Damage to this area can lead to difficulties in these cognitive processes.
