Evoked Potentials

Home / Oferta Formativa / Coimbra Health School / Bachelor / Bachelor in Clinical Physiology

Base Knowledge

The acquisition of theoretical and practical knowledge in the subjects taught requires knowledge of neuroanatomy, neurophysiology and pathophysiology of neurological diseases.

Teaching Methodologies

The teaching of the curricular unit is divided into two components: one theoretical-practical and one practical.

The theoretical-practical teaching aims at the detailed presentation of the programme content through an active, explanatory methodology using auxiliary tools.

The practical component involves the application of study protocols to models, practical application of the programme content developed in the theoretical-practical component, the use of evoked potential equipment and the preparation of study reports.

Learning Results

The student should acquire knowledge about:
 
– Anatomy and physiology of the central and peripheral nervous systems with special reference to the auditory, visual and somatosensory pathways.
 
– Neurophysiological techniques related to evoked potentials.
 
– Operation of evoked potential devices
 
The student should acquire skills and competences in:
 
– Identifying and describing study protocols.
 
– Applying the different techniques and methods while respecting all safety conditions and professional ethics.
 
– Identification of normal and pathological findings.
 
– Solving underlying technical problems.
 
– Contribute to the development of new methods/techniques while maintaining a proactive and critical spirit.
