  1. OK, so I’ve now read Sejnowski’s article and the Kahana article, and one thing has already struck me. These researchers all seem to take for granted that greater spectral power at certain bands represents synchronous, oscillatory behavior. Actually, such increases do not necessarily reflect phase-changes resulting in greater synchrony – they could equally well reflect bursting activity from otherwise silent regions of cortex. Yeung, Bogacz, Holroyd and Jon Cohen (Psychophysiology 41, 2004, 822-832) point out this often-overlooked ambiguity in EEG data, even though many will infer synchrony from the same information without batting an eyelash…
