A new test, which detects “unauthorized brain waves,” can help people with epilepsy to better understand which area of the patient’s brain they need surgery in.
The test was developed by a team of researchers from the Aston Institute of Photonic Technologies (Aston Institute of Photonic Technologies), a department of Aston University. The test can help to determine in advance and with a certain degree of precision which brain area is the epileptogenic zone, i.e. one that causes an epileptic attack.
The special technique used by Aston researchers uses magnetoencephalograms to study brain waves to intercept abnormal electrical discharges in patients with epilepsy and to determine the areas of the brain that cause seizures.
Among the convulsions, there are actually short episodes of brain activity in the form of electrical discharges or “peaks”. A better understanding of these “peaks” can help surgeons understand where to operate better.
The results have been published in the Journal of Neuroscience.
