Is there more than one source for the temporal binding factor for human consciousness?

If the emergence of higher order consciousness is produced by transcerebral electromagnetic processes recreated every 20 msec. to 25 msec., then any f requency band in addition to the 40-Hz range could serve as a binding facto r for this process. Second order differences or "derivatives," obtained by lagging differences in real time between adjacent frequency integers, indic ate that 20 msec. to 25 msec. intervals could be continuously recreated by shifts in frequency within approximately 6.3 and 7.8 Hz. Higher order diffe rences indicate that variations within very narrow band widths between 5 Hz and 6 Hz would generate continuous recreations of 20-msec. to 25-msec. int ervals.
