But, along with quantum mechanics and Darwinism, it’s a topic which frequently finds its way into the stand-up of comedian and all-round brainiac Robin Ince.
Made famous by The Infinite Monkey Cage, his radio show with pop star-turned physicist Brian Cox, Ince is preparing to get your grey matter working once again with In And Out Of His Mind, which comes to Cambridge on 26 September.
Part stand-up comedy, part science lecture, this new show rattles through Freud, Jung, Laing and Milgram on a whistlestop tour of the last 100 years of psychiatry, psychology and skew-whiff brain dabblings. Tickets are £15 and the show starts at 8pm.
