REVIEW OF LITERATURE AND SOME PRELIMINARY RESULTS IN THE DEVELOPMENT OF AN ALERTNESS INDICATOR.
Abstract
The survey of the literature is reviewed as to (1) the brain potentials in wakefulness and sleep and (2) muscle action potentials as diagnostic of degrees of alertness. Recording of muscle spikes in a pilot study was attained by use of a 3-channel Grass, resistance-capacitance coupled amplification system in conjunction with electronic counters. The studies concerned (1) the rectilinear relationship between electronic-muscle-spike-count and amount of tension applied to a muscle, (2) correlation between the electronic counts of specific counters, (3) correlation of electronic count in eye movements in blinking with the number of blinks recorded on an ink-writing oscillograph, and (4) the difference in counts between an attitude of reading and an attitude of voluntary relaxation.
