Our work in Neural Signal Processing focuses on developing signal analysis tools for imaging the central nervous system. We emphasize multivariate signal analysis and probabilistic modeling, drawing heavily on advanced machine learning techniques. Projects on functional imaging are based on Electro-Encephalography (EEG). Experiments in Parra’s high-density EEG recording lab study processes involved in human auditory and visual perception and attention. The latest perceptual modeling work in this laboratory seeks to explain the origin of tinnitus, and develop potential treatment options.
