BackgroundPrestimulus EEG alpha activity in humans has been considered to reflect ongoing top-down preparation for the performance of subsequent tasks. Since theta oscillations may be related to poststimulus top-down processing, we investigated whether prestimulus EEG theta activity also reflects top-down cognitive preparation for a stimulus.ResultsWe recorded EEG data from 15 healthy controls performing a color and shape discrimination task, and used the wavelet transformation to investigate… CONTINUE READING
