This writer, Todd Murphy, also mentions something called "The Forty Hertz Component," a portion of EEG readout, this data correlates with activity within the temporal lobe (6).) Murphy notes that this EEG activity is present both in waking states and in REM states; however, it is absent in non-REM sleep. Apparently the presence of EEG activity within this region supports evidence that a person is truly "existing," communicating with the world around him, and responding to this world. The presence of two temporal lobes regions on opposing sides of the brain work together as one to produce this communicative activity. In the case of temporal lobe epilepsy, individual's temporal lobes are working disconcertedly, thus producing the feeling that there is another being, in addition to the self, that can be sensed (6).) This would account for the reported experiences of seeing angels or devils.
