Clinical & Research Interests

Dr. Seyal is Director of the EEG laboratory and Director of the UC Davis Comprehensive Epilepsy Program that is designated as Level 4 Center (the highest level) by the National Association of Epilepsy Centers. Dr. Seyal’s current research interest is in defining the mechanisms underlying sudden unexpected death in epilepsy (SUDEP). In the recent past he has explored aspects of human cortical physiology using transcranial magnetic pulse stimulation.

He serves on the editorial board of the Journal of Clinical Neurophysiology and provides editorial review for Clinical Neurophysiology, The Journal of Clinical Neurophysiology, Epilepsia and Muscle and Nerve.
