Climbing Fibers

Climbing fibers are nerve fibers in the brain that connect to a specific part called the cerebellum, which helps coordinate movement and balance. They originate from cells in the brainstem and send strong signals to Purkinje cells within the cerebellum. These signals play a crucial role in motor learning by helping the brain modify and refine movement patterns based on experience. Essentially, climbing fibers act as teachers, informing the cerebellum when movements are correct or need adjustment, enabling smooth, precise motor control over time.
