Corff Cymru is a science programme looking at the human body from the perspective of the Welsh. In the second episode of the series we will be focusing on the brain. We'll be looking at the effects of bilingualism on the brain at Bangor University School of Psychology with Professor Debbie Mills' team and Dr Enlli Thomas from the School of Education. We will also be learning how the brain works, at CUBRIC in Cardiff, and finding out more about intelligence.
