Record the brain activity in the occipital lobe and average out the noise to view a visual evoked potential for both a flash stimulus and pattern reversal stimulus.
The aim of this experiment is for students to use the technique of the electroencephalogram, or EEG, to record a visual evoked potential. Students will use the Scope software to complete this experiment. First students will record a visual evoked potential using a flash stimulus; this recording will be compared to that of a checkerboard pattern reversal stimulus. Students will be able to make conclusions about the type of stimuli used in research and clinical settings and determine which variables work best to complete the experiment successfully. The Scope software will record many sweeps of data in order to average out the background noise and amplify the visual evoked potential. The LabChart software is not used in this experiment. This experiment is suitable for students with basic knowledge of the PowerLab Data Acquisition System.
