Auditory evoked potential P300 in adults: reference values
OBJECTIVE To establish reference intervals for cognitive potential P300 latency using tone burst stimuli. METHODS This study involved 28 participants aged between 18 and 59 years. P300 recordings were performed using a two-channel device (Masbe, Contronic). Electrode placement was as follows: Fpz (ground electrode), Cz (active electrode), M1 and M2 (reference electrodes). Intensity correspond...
متن کاملAuditory Evoked Potential Mismatch Negativity in Normal-Hearing Adults
Introduction Mismatch Negativity (MMN) corresponds to a response of the central auditory nervous system. Objective The objective of this study is to analyze MMN latencies and amplitudes in normal-hearing adults and compare the results between ears, gender and hand dominance. Methods This is a cross-sectional study. Forty subjects participated, 20 women and 20 men, aged 18 to 29 years and hav...

متن کاملLate auditory event-related evoked potential (P300) in Down's syndrome patients.
UNLABELLED Down syndrome is caused by a trisomy of chromosome 21 and is associated with central auditory processing deficit, learning disability and, probably, early-onset Alzheimer's disease. AIM To evaluate the latencies and amplitudes of evoked late auditory potential related to P300 events and their changes in young adults with Down's syndrome. MATERIALS AND METHODS Prospective case stu...
