Abstract

Central Auditory Processing (CAP) is defined as the efficiency and effectiveness with which the Central Nervous System utilizes auditory information, modulated by higher-level cognitive functions. Middle and long latency Auditory Evoked Potentials (AEPs) have consolidated as objective neurophysiological tools that reflect the speed and robustness of neuronal processing. The aim of the study is to explore the application of middle and long latency AEPs as objective tools for studying the efficiency of CAP, higher-level cognitive abilities, and the neuroplastic adaptations induced by high linguistic and cognitive demand experience. A narrative review was conducted with 81 documents. Evidence confirms that musical training is associated with greater P300 amplitude and shorter latency, indicating efficiency in attention and processing speed. Bilinguals and musicians show greater grey matter density and greater experience-dependent brain plasticity. The AMLR constitutes a sensitive biomarker of thalamocortical integrity, useful for identifying CAP disorders even when brainstem responses fall within normal parameters. Middle and long latency AEPs constitute objective and sensitive tools for analyzing the efficiency of CAP, higher-level cognitive abilities, and the neuroplastic adaptations induced by high linguistic and cognitive demand experience, with P300 being the most consistent indicator of cognitive and attentional plasticity, and the AMLR a sensitive biomarker of thalamocortical integrity.
