The brain is made up of billions of nerve cells, or neurons, wired together in a highly complex and organised way. But how do they know where to go when the brain is developing?
These remarkable time-lapse movies capture the journey of living neurons in the frog brain. Narrated by Professor Christine Holt, these movies show some of the discoveries of her research group in the Department of Physiology, Development and Neuroscience.

Movie credits: Sonia Witte, Trina Lu Bo, Hanno Svoboda and Christine Holt
