To determine whether or not knowledge of stimulus timing influences the amplitude and latency of evoked cortical potentials, we have studied the evoked potentials of 24 adults under two contrasting conditions in which people knew or did not know the timing of tone stimuli by means of numerical perceptual cuing. Results demonstrated markedly smaller(More)
Habituation of alpha wave suppression to an external auditory signal was studied using computer assisted EEG quantification procedures. Topographic maps of alpha amplitude were constructed from multiple electrode placements for seven healthy adults. The EEG preceding and following 10 standard or habituating stimuli, and 1 novel or sensitizing stimulus, was(More)
