“…This phenomenon of auditory maturation allows the development of auditory abilities, in other words, allows the individual not only to be capable of hearing, but also for sound stimuli heard to be detected, discriminated, recognized and understood (1,2) . In recent decades, Long Latency Auditory Evoked Potentials (LLAEP), traces generated by bioelectric activities from central auditory pathways after acoustic stimulation, have shown themselves to be a resource capable of measuring the neurophysiological modifications resultant from the maturation process (3,4) . For its being an exogenous potential, in other words, not dependent on the behavioral response of the individual, they can be a useful tool to evaluate, amongst other things, small children who have still not developed auditory and/or cognitive abilities to respond to other evaluations (5,6) .…”
