The Brain: Are you pondering what I’m pondering?
Pinky: Yes Brain, but if our knees bent the other way, how would we ride a bicycle?
Ever wonder why adults can throw their leg over a bicycle after years… decades, even… of not pedaling an inch?  Turns out there’s this section of your brain that never forgets what it’s learned…really, just read this article from The Times Of India for proof:
LONDON: Ever wondered why we don’t forget how to ride a bike? Well, researchers from the University of Aberdeen claim to have found an answer to the question. Lead researcher Dr. Peer Wulff has discovered a key nerve cell in the cerebellum section of the brain that controls skills such as riding a bicycle, skiing, or even eating with chopsticks, reports the Daily Express. This nerve cell monitors electrical signals that leave the cerebellum and transform them for storage in other parts of the brain. The “gatekeeper” cell helps brain to remember newly learnt coordination skills. The researchers hope that the new discovery could pave way for creating artificial devices to mimic normal brain functions and benefit those who have suffered brain disorders.
