Neuroscientists celebrating brain wave for troubled minds

Scots experts have discovered the brain’s “rhythmic fingerprints”, which could be used to diagnose and treat conditions ranging from post traumatic stress disorder (PTSD) to dementia.

Brain oscillations – often known as brain waves – caused by electrical waves pulsing through grey matter have puzzled experts since their discovery by German psychiatrist Hans Berger in 1924.

Neuroscientists from Glasgow University have now found that each area of the brain has its own characteristic mix of rhythms, which could be read like a fingerprint using magnetic waves.
