Course Overview
This course will concentrate on advanced topics pertaining to EEG in the field including but not limited to: epilepsy surgery monitoring, the seizure investigation unit, continuous long-term monitoring, and quantitative EEG. EEG interpretation of abnormal and difficult EEGs will continue throughout this course in preparation for the fourth-term practicum. A solid understanding of all basic normal and abnormal EEG concepts is essential for doing well in this course.
