Prof Mark Cunningham, the Ellen Mayston Bates Professor of Neurophysiology of Epilepsy, Trinity College Dublin joins me this week. He chats to me about his fascination with studying the brain, the 'instant gratification' of electrophysiology and his cutting edge research into epilepsy. Mark describes his work using live brain tissue, what an honor it is to work with such precious samples and how you can 'listen to the symphony of brain cells firing'.  He also chats to me about growing up in Newry, the critical influence teachers and a summer research project had on his career and his PhD days in Bristol. This was such a warm, friendly and engaging chat - hope you enjoy!
