The programme will be supported by an ongoing marketing campaign to promote Nintendo's Touch Generation range of software for the Nintendo DS console.
The deal was brokered with Tiger Aspect Productions by Mediaedge:cia and includes sponsorship credits around the show.
The eight-part series, developed and produced by Tiger Aspect and GroupM Entertainment, will put contestants through a series of games designed to push them to their mental and physical limits to see who will be crowned Britain's Best Brain.
Each of the one-hour shows, due to air on Five from October this year, will see contestants tackle five tasks which have been scientifically created to test a specific function governed by a different part of the brain - memory, co-ordination, numeracy, recognition and risk.
Nintendo will hold a six-week nationwide recruitment drive for contestants in UK shopping centres during July and August. Prospective candidates who attend the roadshow will take part in tests on the Nintendo DS and Wii.
