British celebs donate brains for Parkinson's research

British celebrities are hoping to set an example by donating their brains after death to Parkinson's research. Celebrities including Jane Asher -- president of the London-based Parkinson's Disease Society -- and BBC host Jeremy Paxman have agreed to donate their brains and urging others to follow their lead in support of the brain bank at London's Hammersmith Hospital.

"It's not as if you'll be needing it yourself," Paxman said in a statement.
