Abstract
EEG power spectral analysis was studied from 14 (alumina-gel) chronically epileptic, undrugged monkeys [Macaca mulatta] during an EEG operant conditioning experiment. The composite profile of the average epileptic monkey showed the majority of power was 10 Hz. Because of the large variance in the data no significant changes in the EEG power spectra could be detected as a function of conditioning. Possible reasons for this large variance were discussed. Hypothesis from previous human biofeedback studies would allow the prediction that those frequencies corresponding to the .mu. and sensory-motor-rhythm should negatively covary with seizure frequency. Data from this study did not support such assertions. The method of using spectral analysis for quantifying changes in the EEG which covary with operant conditioning was evaluated.Keywords
