This year marks the 75th anniversary of the first lobotomy in America, a practice which thanks to the film and book of One Flew over the Cuckoo's Nest is often associated with the US. But as Hugh Levinson has been investigating, there were actually proportionately more lobotomies here in Britain.

The Lobotomists is on BBC Radio 4 on Monday 7 November at 20:00 GMT. Or listen afterwards via the Radio 4 website.
