Кора генерирует длиннолатентные компоненты слуховых вызванных потенциалов во время звучания сложных акустических стимулов, а средний мозг – после завершения звучания сложных акустических стимулов
The purpose of the study. Identification of components of scalp and deep auditory evoked potentials (EP) that appear in response to change in the acoustic environment. The beginning of the sound of a syllable, the transition from a consonant to a vowel sound and the end of the sound of a syllable were taken as a change in the acoustic environment.Materials and methods. The study involved 29 healthy volunteers (6 men and 23 women; average age 28 ± 10 years) and 2 patients (42-year-old man and 52-year-old man) undergoing surgical treatment of benign neoplasms of the fourth ventricle at the Burdenko National Medical Research Center of Neurosurgery. Auditory EP were recorded in response to a sequence of several syllables and vowel sounds. In this paper, the analysis focuses on the syllables "ba", "da", "sa", "sha", in which the time difference between the beginning of consonant and vowel sound was more than 150 ms.Results. In response to the syllables "ba", "da", "sa", "sha", peaks N1S and P2S appeared on the scalp EP of healthy volunteers after the beginning of the syllable, and peaks N1C and P2C appeared after the transition from a consonant to a vowel...
