Possible demonstration of an observable simple wavelet-opponent process is suggested by examining the research presented in the following article: Dehaene-Lambertz, G. & Dehaene, S. (1994, July 28). Speed and cerebral correlates of syllable discrimination in infants. Nature v370, p292(4). To simply illustrate in format using a typing system let (L) = a large wavelet, (M) = a small wavelet, (S) = a small wavelet, M = a wavelet packet of "ba", W = an inverse or opponent wavelet packet, -> = the direction of the series, and MV = a novel wavelet packet "ga". Using Ghislaine Dehaene-Lambertz and Stanislas Dehaene (1994) research on speech sounds and changes in baby's brains which suggest a mirror image of the stimulus wavelet, we would observe the following series in an average evoked related potential relative to a stimulus series of "ba", "ba", "ba", "ga", "nothing" -> (L)M -> (M)M -> (S)M -> (L)MV -> (M)W Notice that (M)M is the average of the series of the stimulus "ba". Notice that (M)W is an opponent wavelet mirroring the stimulus "ba" when "ba" was removed. The idea is that an opponent wavelet filter for "ba" is being formed which we see as habituation in the series. The wavelet filter does not block the stimulus "ga". The lack of the stimulus "ba" causes a reciprocal inhibition that is a mirror image imposed on a non-stimulus. Ron Blue http://turn.to/ai
