Abstract

The amplitude-temporal and spectral characteristics of the short-latency auditory evoked potentials (SLAEP) recorded under conditions of monoaural stimulation with sound clicks with initial phase of rarefaction followed by compression and alteration, with the intensity of 60 dB and frequency of 11.1 Hz, were studied in ipsi- and contralateral derivations. Substantial changes in SLAEP morphology in response to polarity inversion of the acoustic stimulus were found. Waves II, IV, VI, and VII changed to the greatest extent. The spectral analysis detected three main SLAEP components: low- (LF), medium- (MF), and high-frequency (HF) components as well as the respective frequency bands. Change in the click phase from rarefaction to compression resulted in bilateral redistribution of power between the MF and HF components. This was expressed as a decrease in the HF peak power and simultaneous rise of MF power. Selective effects of the polarity inversion of the sound stimulus on the MF and HF components support the finding that the activity of SLAEP-generating structures are mainly reflected in the mentioned components. It is suggested that two populations of phase-sensitive units are represented in the auditory analyzer. These populations determine the characteristic changes in SLAEP morphology and spectral characteristics.
