In The Human Subject, Dr Adam Rutherford and Dr Julia Shaw investigate the threads connecting modern day medicine to its often brutal origins.

This is the story of patient B-19, a 24-year old who, in 1970, walks into a hospital in Louisiana troubled by the fact that the drugs he’s been abusing for the past three years are no longer having the desired effect. He claims he is “bored by everything” and is no longer getting a “kick” out of sex.

To Dr Robert Heath’s intrigue, B-19 has “never in his life experienced heterosexual relationships of any kind”. Somewhere along the way, during the consultations, the conclusion is drawn that B-19 would be happier if he wasn’t gay. And so they set about a process that involves having lots of wires sticking out of his brain. Julia and Adam hear from science journalist and author, Lone Frank, author of The Pleasure Shock: The Rise of Deep Brain Stimulation and Its Forgotten Inventor.
