Seriously...

Adam Tjolle is a vet with two brains - who once starred on the BBC's Animal Hospital. His second brain - in reality a slow-growing tumour - was discovered by accident on a scan when he fell off his bike.The presenter of the programme, his friend (and psychologist) Claudia Hammond is really interested in what's going on inside his head, so has kept a record - before and after the life-changing surgery.Adam's biggest fear is losing his memories - so he asks friends and family to send patches of fabric to make a special hat - to remind him of them as well as keep his head warm in chilly Edinburgh.The surgeon will operate while Adam is wide awake - being careful to cause the least damage possible to the area of his brain which controls spatial awareness, time perception and his decision-making skills, while also removing as much of the tumour as possible.Producer: Paula McGrath Presenter: Claudia Hammond.
