Особенности потенциала, следующего за частотой, зарегистрированного в ответ на изменения в параметрах звучания речевого сигнала (изолированного слога)
The aim of this study was to evaluate the frequency following response (FFR) for the analysis of the intact perception of syllables in humans. For this purpose, event-related potentials (ERPs) in response to isolated Russian syllables were recorded and analyzed in 29 healthy persons in two frequency ranges, standard (1-40 Hz) and high frequency (70-150 Hz), and the identified peaks were compared with the local-field potential of two patients, recorded directly from the midbrain during intraoperative neurophysiological monitoring. In the standard frequency range, in response to the onset of a sound and the transition from a consonant to a vowel, a negative peak with a latency of about 100 ms from the analyzed event was identified in the ERPs. In the high-frequency range, components of FFR was identified in response to the onset of a syllable and the transition from a consonant to a vowel, similar to oscillations in the local evoked responses of the midbrain of patients...
