Magnetoencephalography (MEG): Source Imaging the Neural Loci of Epilepsy and Imagination

  • Toronto Western Hospital 399 Bathurst Street Toronto, ON, M5T 2S6 Canada (map)

Speakers: Dr. Richard Wennberg and Dr. Luis Garcia Dominguez

Richard Wennberg (left), M.D., Ph.D., FRCPC, is a neurologist who is internationally known for his work in electroencephalography (EEG) and magnetoencephalography (MEG), epilepsy, mild traumatic brain injury (concussion), and autoimmune encephalitis. He is a Professor of Medicine at the University of Toronto, past Chair of the Royal College of Physicians and Surgeons of Canada Examination Board in Neurology, and past President of the Canadian League Against Epilepsy. He is the director of the clinical neurophysiology laboratory and Mitchell Goldhar MEG unit, Krembil Brain Institute, Toronto Western Hospital, and a member of the NHL/NHLPA Second Medical Opinion List. His research is focused on (a) exploring the neurophysiological mechanisms linking brain function and behavior, normal and abnormal, and (b) improving current understanding of the biophysical bases of clinical neurophysiology.

Luis Garcia Dominguez (right), Ph.D., is a scientist at the Toronto Western Hospital, clinical neurophysiology laboratory and Mitchell Goldhar magnetoencephalography (MEG) unit, primarily focused on locating epileptic seizure foci in the brain and evaluating the efficacy of beamformer analysis in epilepsy. His work includes studying seizure-related neuronal synchronization and understanding the limitations of MEG and electroencephalography (EEG) synchronization analysis techniques. He also researches cognitive function, including language, memory, and motor imagery, both in typical and pathological contexts such as autism, schizophrenia and dementia. He has developed tools such as a MATLAB interface for signal processing and cluster-based statistical methods for analyzing brain responses.
