Washington: In a breakthrough, scientists have successfully discovered how to identify abnormal brain rhythms associated with Parkinson`s, paving way for gen-next therapeutic devices for the disease.The work by a team of scientists and clinicians at The University of California, San Francisco (UCSF) sheds light on how Parkinson`s disease affects the brain, and is the first time anyone has been able to measure a quantitative signal from the disease within the cerebral cortex - the outermost layers of the brain that helps govern memory, physical movement and consciousness."Normally the individual cells of the brain are functioning independently much of the time, working together only for specific tasks," said neurosurgeon Philip Starr.But in Parkinson`s disease, he said, many brain cells display "excessive synchronisation," firing together inappropriately most of the time."They are locked into playing the same note as everyone else without exploring their own music," Starr said in a statement.This excessive synchronisation leads to movement problems and other symptoms characteristic of the disease, according to the study published in the journal Proceedings of the National Academy of Sciences (PNAS).
