How does emotion influence decision-making? Prof Ray Dolan explains to AC Grayling how we don’t necessarily get wiser as we get older and asks whether drugs can restore our ability to think clearly.

Prof Dolan is the Mary Kinross Professor of Neuropsychiatry at University College, London, and Director of its Wellcome Trust Centre for Neuroimaging. A pioneer in the neuroscience of decision-making, he investigates the structures in the brain involved in decision-making, using advanced techniques of neuroimaging and behavioural analysis.
