Amelia Nurse talks to Belgian neurosurgeon and brain researcher Dirk De Ridder about what goes on in the brain when you have a spiritual experience; whether repeated spiritual experience can change the brain; the Geschwind syndrome; if there’s a “God Spot” in the brain - and what’s involved in the study of all this. Dirk De Ridder was recently appointed as the inaugural Neurological Foundation Professor of Neurosurgery at the University of Otago.
