Why do falls rise with age? Study points to cerebellar neuron firing

A new McGill University study has found a direct link between age-related declines in neuron activity in the cerebellum and worsening motor skills, including gait, balance and agility. While it is well known that these abilities diminish with age, this is the first research to pinpoint how changes in Purkinje cells—a key type of cerebellar neuron—drive…
