The Thought Chamber is a room devoid of all light and sound, where a guest is left alone and asked to vocalise their thought processes and reveal the inner workings of their mind.
The Thought Chamber is a room devoid of light and sound, where a guest is left on their own for up to an hour. During that time, they are asked to vocalise the thoughts that come into their head, resulting in a snapshot of the inner workings of their mind.
In many ways, the results are much more revealing than a traditional interview, as no one can anticipate the subject matters or the direction of where the mind is going. We hear memories, fears, concerns, ambitions, insights, dreams, fantasies - as well as the day-to-day mundane problems that everyone faces.
One minute the guest may be dreaming about flying around the universe - the next he or she is worrying about what to get the kids for tea tonight.
There's no script, no questions, no stimulus - just the random workings of the brain.
Guests during the series include: award winning artist Grayson Perry; scientist and presenter of The Sky at Night, Dr Maggie Aderin-Pocock; and musician and drummer from Radiohead, Phillip Selway.
