Auditory Electrophysiology II

It is recommended that students have already acquired the knowledge taught in the Electrophysiology I course.

It is also recommended that students have already acquired notions of neuroanatomy and pathology of the auditory system, in order to understand the content taught that involves these concepts.

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; collection, analysis and marking of waves; analysis and discussion of clinical cases; 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:

− know the purpose and clinical applications of Auditory Middle Latency Response, Auditory Long Latency Response, P300, Mismatch Negativity, N400, Auditory Electric Evoked Potentials and Electroneuronography;

− know the procedures and to know the stimulation and acquisition protocols and parameters appropriate to the purpose of the Evoked Potentials (EP) exam;

− know how different variables influence EP;

− determine electrophysiological auditory thresholds;

− know how to mark waves components, analyze and relate the results of the Auditory Evoked Potentials with the clinical case, depending on whether the assessment is audiological, neurological and about neuroplasticity.

− know research guidelines in auditory electrophysiology.

Auditory Middle Latency Response (AMLR), Auditory Long Latency Response (ALLR), P300, Mismatch Negativity (MMN) and N400

− Introduction, definition, stimulation and acquisition procedures, protocols and parameters, response components, processes involved, variables with influence on the response, audiological evaluation and electrophysiological auditory thresholds, neurological and neuroplasticity evaluation, analysis and interpretation of the response, clinical applications, analysis of waves components and clinical cases, research guidelines;

Electrical Auditory Evoked Potentials and Electroneuronography (Enog)

− Introduction to electrophysiological auditory and non-auditory electrically evoked responses, procedures, stimulation and acquisition parameters, response components, variables influencing the response, analysis and interpretation of the response, clinical applications.

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 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;
The TP assessment grade is the weighted average of a written assessment/frequency (70% in the final grade of the TP assessment and the minimum grade is 9.5) and a written work (30% in the final grade of the TP assessment).

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.
