Signalling pathways of the cerebellum

The cerebellum represents only 10% of the total volume of the brain, but contains over 50% of the brain’s neurons.^{5} The cerebellum is responsible for fine-tuning motor activities and adjusting ongoing movements, and plays a role in maintaining balance and posture, coordinating voluntary movements (e.g., gait), and motor learning^{1-3}. It receives sensory input from the body (muscles, tendons, and joints) and motor input from the cerebral cortex^{1,3}

The cerebellum also receives information concerning balance from the vestibular system^{3}.

Damage to the cerebellum can result in ataxia (problems with fine movements, impaired coordination and balance).^{2,3}
