Competency-Based EEG Education

Welcome to the EEG Atlas featuring "must-know" EEG findings for neurology residents as identified by the International League Against Epilepsy (ILAE) and epilepsy education experts.

This atlas contains the core EEG patterns that every neurologist should be able to recognize based on competency-based curriculum studies.
