An attempt was made to determine the relationship between the somatosensory evoked response (SER) and preceding EEG activity. A canonical correlational analysis of a number of parameters derived from both prestimulus and poststimulus cerebral events revealed a complex pattern of relatedness between the two sets of electroencephalographic variables. However, the contribution made by each parameter to the canonical correlation showed little consistency across Ss. Moreover, the amount of variance in one set of parameters accounted for by the other set was relatively small. It was concluded that the SER, as recorded from the vertex, is essentially independent of ongoing EEG rhythms. |
