Estudo do efeito de supressão no potencial evocado auditivo de tronco encefálico

Abstract: TEMA: o efeito de supressão com ruído branco contralateral verificado sobre o potencial evocado auditivo de tronco encefálico pode ter influência do sistema auditivo eferente. OBJETIVOS: avaliar o efeito de supressão com ruído branco contralateral no potencial evocado auditivo de tronco encefálico em indivíduos com limiares auditivos dentro da normalidade. MÉTODOS: participaram desta pesquisa 25 indivíduos, de 18 a 30 anos de idade, de ambos os sexos, que foram submetidos à anamnese, inspeção do meato acústico… Show more

“…The AEP may be classified, according to their onset time, into short, middle or long latency (1)(2)(3) . The components of the Long-Latency Auditory Evoked Potentials (LLAEP) are represented by peaks, according to the polarity and the latency value, that have positive (P) and negative (N) voltage (4) .…”

“…Changes in any portion of the auditory pathway prevent the development of these abilities from occurring fully (1) . Therefore, it is recommended that, in order to obtain an audiological diagnosis with more accuracy, objective and subjective assessment methods should be associated (2) . It is also important that tests capable of investigating auditory processing be incorporated into clinical practice (1) and, according to the American Speech-Language-Hearing Association (ASHA), it is recommended to use the electrophysiological evaluation for the Study of auditory abilities (3) .…”

“…The most commonly performed analysis occurs through the observation of wave latency and amplitude. When latencies increase or decrease in amplitudes, clinical and subclinical changes are objectively evidenced (2) . Latency informs the course time of processing activity, while wave amplitude demonstrates the extent of neural allocation involved in the cognitive processes of potentials (10) .…”
