Abstract

O objetivo deste estudo foi avaliar os resultados do potencial cognitivo auditivo em um grupo de adultos normais. Os testes foram realizados registrando-se a resposta evocada em Cz e Fz. Os dados obtidos foram analisados estatisticamente. São descritas neste trabalho as latências médias de N1, P2, P2AP, N2 e P3, a amplitude de P3, bem como o desvio padrão destas variáveis. Comentam-se algumas dificuldades encontradas na interpretação do teste destacando as limitações de seu uso clínico.The objective of this study was to evaluate the results of the auditory cognitive potential in a group of normal adults. The evoked response was obtained at Cz and Fz. The data collected were statistically analysed. The mean latencies of N1, P2, P2AP, N2, P3 and amplitude of P3, as well the standard deviation of these variables were presented. We briefly comment on some pitfalls related to interpretation of the results as well as the limitations of the tecnique as a diagnostic tool.
