Abstract
inst log frequency, revealed 1/f spectra in both pre- and post-stimulus segments for CS- and CS+ stimuli. The y-intercepts and slopes for average PSDs were significantly different between pre- and post-stimulus segments, owing to the evoked potentials, but not between CS- and CS+ stimulus segments. 6.##### Spatiotemporal patterns were invariant over all frequency bins from 20-100 Hz in the 1/ f domain. Spatiotemporal patterns in the 2-20 Hz domain progressively differed from the invariant patterns with decreasing frequency. 7.##### In the spatial frequency domain, the logarithm of the average spatial FFT power spectra from pre- and post-stimulus neocortical EEG segments, when plotted against the log spatial frequency, fell monotonically from the maximum at the lowest spatial frequency, concavely curving to a linear 1/f spectral domain. This curve in the 1/f spectral domain extended from 0.133 - 0.880 cycles/mm in the PPC and from 0.095 - 0.624 cycles/mm in the neocortices. 8.#####
