If you've ever wondered about how the human brain works, look no further than Professor Niall Tubridy's new book.

Tubridy is a neurologist and the author of Just One More Question: Stories from a Life in Neurology, which gives an insight into his career and the people and cases he has encountered along the way.

His interest in neuology began at a young age, and he describes neurologists as "a strange breed of doctors."

"Because you can't see the brain, a lot of it is based on listening to patients’ stories. It's an old-fashioned branch of medicine."

"Everything begins and ends in the brain as far as I'm concerned."

He joined us to discuss the book and areas such as memory, behaviour, the difference between the left and right sides of the brain, and whether it's actually possible to overuse your brain.
