Research scientists working on combating paralysis at Stanmore's Royal National Orthopaedic Hospital will star in a BBC show to help choose the theme of the £10milliion Longitude Prize for science.
Staff from the Brockley Hill hospital's Aspire Centre - part of the University College London's Institute of Musculoskeletal Sciences - will demonstrate how state-of-the-art brain-controlled robots can advance treatment of paralysis.
Dr Tom Carlson appears on the programme, 'The £10 Million Challenge', being broadcast at 9pm on BBC2.
The Longitude Prize 2014 is a challenge with a £10million prize fund being run by Nesta, the technology strategy board.
One of six proposed challenges - concerning water, paralysis, antibiotics, food, dementia and flight - will be selected as the conundrum that scientists will be invited to solve between now and 2019.
Dr Carlson said: " In the UK, a person is paralysed every eight hours.
"How we can restore movement to those with paralysis is one of the biggest scientific challenges the world is facing today.
"The work we are doing with University College London at the RNOH is vital in advancing research in this area and I would encourage everyone to tune in tonight and support our bid by voting online.”
The Longitude Prize commemorates the 300th anniversary of the original 1714 Longitude Prize - the £20,000 reward for finding a way to determine longitude at sea accurately.
A new Longitude Committee has selected the six themes in the final and the public will vote for its favourite between today and June 25 in a poll being run by the BBC's Horizon programme.
Once the winner is chosen, the committee will devise the criteria on how to win the prize and from September solutions will be invited. The £10million prize will be available for five years.
