Auditory electrophysiology

Base Knowledge

Basic knowledge of: anatomo-physiology and pathology (general and of the audio-vestibular system), biology, biophysics, clinical audiology and paediatric audiology.

Teaching Methodologies

Lectures and practical classes in the Audiology laboratory (application of different knowledge of ABR, ASSR, AMLR, ALLR, P300, MMN);
Small group work for analyzing and relating clinical cases and articles, marking tracings and preparing AEP reports and creating research protocols.
Attendance to students in the teachers’ offices/at a distance.

Learning Results

To know define Auditory Evoked Potential (AEP) and to know which variables influence the AEP;
To know how these variables influence the different AEP with special emphasis on Auditory Brainstem Response (ABR);
To know what the possible outcomes in the evaluation by ABR, whether auditory or neurological evaluation;
To interpret ABR by click and tone burst and relate them to possible pathologies;
To interpret Electrocochleography (ECochG) by click and tone burst and relate it to possible pathologies;
To have Knowledge of Auditory Steady State Response (ASSR), Auditory Middle-Latency Response (AMLR), Auditory Late Response (ALPs), P300 and Mismatch Negativity (MMN);
To define AEP, to describe the objectives and fundamental parameters of the AEP;
To enumerate the different variables that influence the AEP and to describe how the different variables influence the ABR, ECochG, ASSR, AMLR, ALPs, P300 and the MMM.
To analyze AEP;
To interpret the ABR of neurological assessment and audiological assessment and to define the electrophysiological threshold;
To relate the results of ABR with possible injury site.
