SUMMARY REPORT FOR THE PERIOD 1 JUNE 1969 THROUGH 31 MAY 1970 UNDER CONTRACT N00014-67-A-0126-0010,
Abstract
The average of EEG responses recorded from several locations on the human scalp were examined for evidence of relations between monaural and binaural stimulus parameters and response waveforms, component latencies and interhemispheric differences. Two principal waveforms were discovered and described; they have been designated simply Form I and Form II. Form I exhibits three small negative-voltage peaks, N0, N1 and N2, separated by two positive-voltage troughs, P1 and P2, the whole followed by the prominent P3. Form II lacks the earliest negative peak seen in Form I, and N2 and N3 blend together so that there is no clear positive voltage before the typical prominent P3. Form I is associated with the left hemisphere and one-ear stimulation, while Form II is more frequently associated with the right hemisphere and dichotic stimulation. The results require validation on other subjects. Another finding is that, irrespective of the location in auditory space of a stimulus, the right hemispheric response always differs from that of the left hemisphere. Consistencies are being sought in these differences related to brief 'melodic' patterns and other stimulus parameters. (Author)
