Abstract
To investigate the system specificity of learned changes in EEG spectra in man and to rule out the possibility that changes in cardiac or respiratory activity mediate the observed central nervous system changes, 14 subjects were trained to produce occipital alpha and beta frequency activity differentially. Standard operant methods, including a discriminative stimulus, were used. Heart and respiration rates were recorded simultaneously. Subjects showed discriminant control of the EEG spectra, but no significant changes were found in either heart or respiratory systems. Our data indicate that conditioned changes in the EEG spectra are not mediated by shifts in either heart or respiration rates. Instead they suggest that the EEG generating system is relatively independent of the brain systems controlling respiration and heart function.
