L04 Electroencephalography II

Alpha Rhythms in the Occipital Lobe
In this BSL Lesson, students will discover how the brain constantly receives sensory input and integrates the information before processing it. The students will record EEG data from the occipital lobe while performing a number of tasks. The system will record and display the raw EEG together with the alpha wave and alpha-RMS activity. Students will compare their baseline EEG with the data recorded during the different tasks.

Experimental Objectives

To record EEG from an awake, resting subject under the following conditions:

  1. Relaxed with eyes closed;
  2. Performing mental arithmetic with eyes closed;
  3. Hyperventilating (breathing quickly and deeply) with eyes closed;
  4. Relaxed with eyes open.

To examine the differences in the level of alpha rhythm activity during mental arithmetic and hyperventilation, compared to the control condition of eyes closed and relaxed.

Tasks Performed by the Student

BSL Lessons are designed to allow at least four students to record and save data in a normal lab period (60-90 minutes). Typically, labs work most efficiently with three or more students working together at each BSL station.

Using Facial Expressions to Understand Behavior

Learn how to collect and interpret facial expressions data with facial coding software called FaceReader, and how to synchronize with other biometric response. FaceReader is an emotion reading software that analyzes facial movements to classify subject response. Facial expressions can be classified as happy, sad, scared, disgusted, surprised, angry, contempt, and neutral.
