AP PSYCHOLOGY

Detailed explanation-1: -The cerebellum fine tunes motor activity or movement, e.g. the fine movements of fingers as they perform surgery or paint a picture. It helps one maintain posture, sense of balance or equilibrium, by controlling the tone of muscles and the position of limbs.

Detailed explanation-2: -The cerebellum plays a role in processing procedural memories, such as how to play the piano.

Detailed explanation-3: -In general, primary motor cortex encodes the parameters that define individual movements or simple movement sequences. Primary motor cortex neurons fire 5-100 msec before the onset of a movement.

Detailed explanation-4: -Your cerebellum is part of your brain that helps coordinate and regulate a wide range of functions and processes in both your brain and body. While it’s very small compared to your brain overall, it holds more than half of the neurons (cells that make up your nervous system) in your whole body.
