Motor aging results from cerebellar neuron death.


As we age, movements become slower and inconsistent and require more attention. These hallmarks of aging suggest a switch from predictive to reactive motor control. Here I examine evidence supporting the hypothesis that motor aging is primarily determined by the early death of neurons in the cerebellum, a critical structure for predictive motor control.
