They say that once you have learnt to ride a bicycle you never forget - and now neuroscientists at the University of Aberdeen have discovered why. Research published this month has identified a nerve cell in the brain that controls the formulation of memories for skills such as eating with chopsticks, skiing and riding a bike. When a person learns a new motor skill, the cerebellum assimilates the co-ordinated movement. The researchers discovered that one particular nerve cell - the molecular layer interneuron - acts as a gatekeeper that controls signals to the cerebellum. The findings may pave the way for advancements in prosthetics to mimic normal brain function for stroke victims and multiple sclerosis sufferers.
Thanks for the memories
