Why don’t we forget how to ride a bike?

Recent neuroscience research has shed some light on why memories of complex co-ordinated activities like riding a bike are resilient. According to one theory, different parts of memories are scattered throughout the brain.

When we activate a memory, other memories partly stored in the same locations, such as how to pedal, could be reinforced. Another idea is that a nerve cell called the molecular layer interneuron interacts closely with the cerebellum, a part of the brain that helps us do complex things.

This cell takes memories encoded in electrical signals coming out of the cerebellum and somehow makes them very persistent.
