What causes the characteristic slowing of movement in patients with Parkinson’s disease? EEG recordings from the brains of Parkinson’s patients may offer some answers, according to researchers, in
Electrical oscillations of nerve cells deep inside the brain and the cortex are pathologically coupled with one another. Researchers know this from recordings taken from the brains of Parkinson’s patients during surgery to fit a brain pacemaker.
But is it possible to detect this coupling if the electrical nerve activity is only derived from the patient’s scalp, by electroencephalogram (EEG)? Doctoral researcher Ruxue Gong investigated this with a team of scientists led by Professor Joseph Claßen, Director of the Department of Neurology at Leipzig University Hospital, and Professor Thomas Knösche from the MPI for Human Cognitive and Brain Sciences, a media release from Universität Leipzig explains.
