“…similar to the data of Hamel et al(11). This associated finding in the spontaneous EEG and the photic driving responses, both reflecting a relative hypoexcitability by the increase in slower and decrease in faster frequencies, is consistent with the known dependent interaction between spontaneous and evoked activity (16,17). Thus, the H group showed a relative hypoexcitability in the spontaneous EEG activity and its related photic driving; according to the prevailing view, these effects would likely have occurred at the level of the cortical dendrites under the influence of the reticular formation (18).…”
