British scientists say they’ve invented a new type  of brain scanner that patients can wear on their head – allowing them to move while being tested.

The scanner records the magnetic field produced by brain activity and can show precisely where in the brain these movements are being controlled.

The area of the brain shown in blue is where wrist and arm movements are controlled while playing bat and ball.

“Neuroscientists will be able to invisage a whole new world of experiments where we try to work out what a brain is doing but whilst a person is behaving naturally,” said Matt Brookes, a physicist at Nottingham University.

The scientists say the technology will also be beneficial for children with epilepsy and people with movement disorders like Parkinson’s disease. The scanner was developed in the same lab that came up with the MRI, in the 1970’s.

The new research is published online in the journal “Nature.”
