The rhythmic waves in this case might have represented the arterial pulse at the temple--that is, the ENG may have functioned as impedance plethysmography of the artery.
The increased resistance caused by the blood volume lowered the voltage, which might have appeared on ENG as a downward (i.
A strip-chart recorder is satisfactory, but when it must be replaced, a computerized ENG
