Final answer:
The prefrontal cortex is the part of the brain associated with analytical thinking, responsible for functions like decision making, abstract reasoning, and complex problem-solving.
Step-by-step explanation:
The part of the brain used for analytical thinking is the prefrontal cortex. This region is responsible for high-level cognitive functions, including analysis, evaluation, and complex problem-solving.
For instance, when engaging in activities such as comparing literary characters, studying bodily processes in anatomy, or solving math problems, you are utilizing your analytical intelligence. Additionally, the cerebrum as a whole, particularly with its four lobes, plays a major role in higher mental functions such as memory, learning, and language—an integral part of analytical thinking.
The prefrontal cortex handles tasks related to decision making, information processing, abstract reasoning, and controlling impulses, which are components of executive functions. These areas continue to mature through adolescence. Understanding these brain functions is important, especially considering how our brains manage a significant portion of the body's resources—about 20%—to support these energy-intensive activities.
