The award funds research to objectively measure brain activity related to subjective and somatic tinnitus using fNIRS technology, aiming to correlate these measures with tinnitus severity and develop predictive machine learning models.
Description
This project aims to identify objective neural correlates of subjective and somatic tinnitus using functional near-infrared spectroscopy (fNIRS) to measure brain changes in auditory and non-auditory cortices. The study will investigate hemodynamic responses and resting state functional connectivity in tinnitus patients, including those who can modulate their tinnitus with head and neck movements, to develop predictive models using machine learning.
