[Physiological variations of auditory brain-stem evoked potentials]

From the beginning brainstem evoked response audiometry (BERA) has become a technique more and more useful in the daily clinic. In order to know the influence that over BERA have the stimulation parameters, record and individuals variables of each patient, we have developed a study over 50 healthy persons of both sex, with standard technical conditions of the studied different parameters. We agree with other authors in the mean latency values and waves amplitudes, except from the polarity in which our findings are different from those of the literature.
