Anand discovers that an easy task, like kicking a football, needs multiple parts of the brain to coordinate in order to work smoothly. Assistant Professor Jessica Bernard from Texas AMU studies the brain, particularly the cerebellum, a part that controls smooth movements. Dr Bernard explains how tiny glitches and larger lesions
