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.
