Brief description of the Project:

Research Question: Near-Infrared Spectroscopy: a tool for objective assessment of Cochlear Implant success.

Background:
Near-Infrared-Spectroscopy (NIRS) is a non-invasive neuro-imaging technique that allows to map neural activity without the use of magnetic fields like fMRI of MEG. The technique is therefore particularly interesting to be used on patients with a Cochlear Implant (CI) or Hearing Aids, as these patients cannot be measured with the fMRI and MEG techniques. We have recently applied the technique to measure activity from the human auditory cortex during acoustic and audiovisual stimulation, and some preliminary results are encouraging. However, improvement regarding the infrared electrodes are still needed to optimize the success and robustness of the technique.
In this project we will apply NIRS to normal-hearing subjects and patients with a CI to test the signal transmission to the auditory cortex.

Aim: The study will lead to a publication in a peer-reviewed international scientific journal (e.g., the Journal of the Association of Research in Otolaryngology, JARO).
Proposed start: any time

Background knowledge:
Master CNSc: The obligatory courses of the Perception and Action program. The elective course on Auditory Perception is desirable, but not obligatory.
