What part of the brain is responsible for executive functions such as decision making and problem solving?

The frontal lobe is critically involved in executive functions, which include decision making, problem solving, planning, and self-regulation. This area of the brain is responsible for higher-level cognitive processes that allow individuals to assess situations, weigh options, and make informed choices. The frontal lobe integrates information from various other parts of the brain and utilizes this information to guide behavior, control impulses, and execute complex tasks.

While the midbrain plays roles in vision, hearing, and alertness, and the hippocampus is essential for memory formation, including spatial memory and learning, the amygdala is primarily involved in emotional processing and the formation of emotional memories. Therefore, these areas do not primarily regulate the executive functions associated with decision making and problem-solving as effectively as the frontal lobe does.
