Program | Further information





Further Information

Learning outcomes of the course:

This course aims to develop advanced technical and scientific competencies on the domain of visual neurophysiology and the interaction with retinal image formation, processing and interpretation with the goal that the post-graduation student develops competitive research in the area of visual electrophysiology in healthy and disease eyes as well as the modification of the electrophysiological response through different optical interventions.

Directed to PhD Students and final year MSc Students in any field related with clinical research and clinical practice.


Visual electrophysiology and paths to optical intervention


1. Learning outcomes of the curricular unit (knowledge, skills and competences to be developed by students):

In the end of the course, the students must be able to:

  • Understand the neurobiological mechanisms involved in the visual process.
  • Demonstrate advanced knowledge of retinal layers and visual pathways in the visual process.
  • Understand the origin of the bioelectrical signals in the retina and interpret the intrinsically characteristics signals of each cellular group.
  • Be able to perform the different electrophysiological techniques for retina and visual cortex assessment and evaluate those electrophysiological activity using appropriate protocols.
  • Construct computational models of the electrophysiological activity of the retina
  • Hypothesize routes for future research and design research protocols involving electrophysiological and neurophysiological modeling techniques.
  • To develop competitive research about electrophysiological response of the eye in diseased and healthy eyes and relate it with the response obtained by the induction of different customized optical stimuli
