H10 Hemispheric EEG

Derived from original work created by Pr Jean-Frans Lambert and Nicole Chantrier, Institut d’Enseignement istance / Universitaris 8- Saint-Denis France

Experimental Objectives

1. To demonstrate how alpha rhythm (around 10 Hz) takes place of a more rapid rhythm called beta (around 15 to 40 Hz).
2. To observe various stop reactions that represent temporary interruptions of alpha rhythm, following a sensory stimulation or change in attitude (attention focus), that give way to beta rhythm.
3. To analyze the spectrum of frequencies that constitute alpha rhythm.
4. To compare the distribution of alpha rhythm between the two cerebral hemispheres.

Tasks Performed by the Student

Subject will:

• sit in a relaxed state with eyes closed/open at variable intervals of eye opening,
• listen to various types of auditory stimulation, and
• close eyes and perform mental math.
