Experimental study of the auditory and visual averaged evoked potentials (AEPs) recorded during hyperoxia, and investigation of the effect of hyperoxia on the so-called contingent negative variation (CNV). No effect of hyperoxia was found on the auditory AEP, the visual AEP, or the CNV. Comparisons with previous studies are discussed.
EEG analysis for poststimulus events, examining contingent negative variation and late positive wave of average evoked potential
Auditory averaged evoked potentials to clicks in man subjected to selective listening task, comparing effect on attended and rejected ear
Circuit design and performance of cardiotachometer with linear indication of beat-to-beat heart rate, noting input clipping and filter circuits
Human heart rate response following two durations and intensities of auditory stimulus
Cardiotachometer detects and displays the human heart rate during physiological studies. It provides linear response to the heart rate, records heart rate during rest and under heavy stress, provides a beat-to-beat indication of changes in heart rate, and is relatively free of interfering signals from activities other than the heart rate.
