Unit 3: Electroencephalography (EEG) In this section, you will learn about measuring the brain’s electrical activity, a process called electroencephalography, or EEG. This lab reviews the different types of brain waves using specific software called Biopac. You will learn all about Biopac, including how to attach the electrodes to a subject’s head and how to record and interpret data.
Unit 3 Time Advisory
This unit will take approximately 4 hours to complete.

Assessment: McGill University: Physiology Virtual Lab: “EEG: Introduction” and Biopac Science Lab: “EEG” Links: McGill University: Physiology Virtual Lab: “EEG: Introduction” (HTML) and Biopac Science Lab: “EEG” (PDF)
Instructions: Please first read “EEG: Introduction” for an overview of EEG and brain waves. Then read the second link, “EEG,” to learn how to record EEG activity. To open the PDF, click on the second link called “BioPAC Teachers_Guide.pdf.” Pages 3 through 5 of this second link describe the electrodes and their placement; pages 12 through 13 explain the objectives and experimental procedures; and pages 50 through 53 walk you through the experiment itself and the data collection (this final section also includes an Answer Guide).
