"We study the dynamics of electrical activity in different brain systems under normal conditions and in different neurological diseases (epilepsy, Parkinson's, Alzheimer's) in order to develop new biomarkers for early diagnosis and to develop new therapeutic tools and strategies, based on the neuromodulation of these biomarkers", Dr. Julio Artieda.
