Nicolas Roehri, a researcher in the Department of Clinical Neuroscience, is one of two winners of the Swiss League Against Epilepsy's Research Encouragement Award. 

Nicolas Roehri uses electroencephalogram (EEG) and magnetic resonance imaging (MRI) data to locate the source of electrical activity in the brain (electric source imaging, ESI). In the award-winning project, he aims to validate a new method (FAST-IRES) and compare it with other conventional ESI methods using a rare dataset consisting of intracranial EEGs and high-density surface EEGs recorded simultaneously. These methods are particularly useful for examining patients with treatment-resistant focal seizures for whom epilepsy surgery is a possibility. The results would make it possible to more precisely delineate the irritative zone in which typical epileptic potentials appear without requiring the surgical implantation of electrodes.
