The part of the brain that controls balance and coordination is the cerebellum. Located at the back of the brain, the cerebellum plays a crucial role in integrating sensory information from the body to fine-tune motor activity. It helps maintain posture and ensure smooth, coordinated movements. The cerebellum receives input from the vestibular system and proprioceptors, allowing it to adjust movements for tasks such as walking, running, and fine motor skills. Dysfunction in this area can lead to balance disorders and coordination difficulties.
