Auditory Electrophysiology I

It is recommended that students have already acquired notions of neuroanatomy and pathology of the auditory system, in order to understand the concepts that will be taught regarding the generators of auditory evoked potentials, and the changes identified in clinical cases.

Lectures with audiovisual resources; practical classes in the audiology laboratory, where students are divided into groups to apply the different knowledge of AEPs; group works; availability and analysis of scientific articles; analysis of waves; analysis and discussion of clinical cases; prepare AEP reports; clarification of doubts. Up to 25% of lectures can be taught at a distance.

The learning objective of the curricular unit is to provide students with the ability to:
− define concepts in the field of auditory electrophysiology;
− know the purpose and clinical applications of auditory evoked potentials (AEP), namely Electrocochleography, Auditory Brainstem Response, Automatic Brainstem Response and Auditory Steady State Response;
− know the procedures and to know the stimulation and acquisition parameters and protocols appropriate to the clinical case, age and the purpose of the AEP exam;
− know how different variables influence the AEPs;
− determine electrophysiological auditory thresholds and to estimate the auditory threshold;
− know to mark wave components, analyze and relate the results of the AEP with the location of the injury or possible pathologies;
− report the results of the auditory electrophysiological examination.

Auditory Electrophysiology and Auditory Evoked Potential (AEP)

− Introduction, definition, laboratory, instrumentation, software, material, classification of AEPs, parameters and variables related to stimulus, acquisition and individual;

Electrocochleography (ECochG), Auditory Brainstem Response (ABR), Automatic Auditory Brainstem Response (AABR), Auditory Steady State Response (ASSR

− Introduction, definition, stimulation and acquisition procedures, protocols and parameters, response components and anatomical generators, variables with influence on the response, audiological evaluation, electrophysiological auditory thresholds and auditory threshold estimates, neurological evaluation, normative values and criteria for neurodiagnosis, analysis and interpretation response and relationship with the pathology site, clinical applications, analysis of traces and clinical cases, examination report;
Presentation, clarification of doubts and evaluation.

Continuous evaluation:

The final grade of the curricular unit is the weighted average of the TP assessment and the practical assessment and must be at least 9.5 points;
The TP assessment consists of the weighted average of two written assessments (frequencies);
The TP assessment has a weight of 70% in the final grade and the minimum grade is 9.5;
The practical assessment has a weight of 30% in the final grade and the minimum grade is 9.5.

Assessment by exam:

The final grade of the curricular unit is the weighted average of the TP assessment (with a weight of 70%) and the practical assessment (with a weight of 30%) where the minimum grade in each assessment must be 9.5 points.
