Timing perception is an inherent feature of all sensory experience. Without its underlying temporal structure, perception would be unthinkable. To efficiently perceive and interact with our environment, we perceive sequences of sensory events and derive predictions about future events based on previous sequences. The ability to extract such temporal patterns from the ongoing stream of stimulation – here referred to as global timing – is a fundamental capacity of the human brain. However, despite the crucial importance of global timing for perceptual efficiency, the underlying neural mechanisms are virtually unknown.
This project investigates the brain organization of high-level auditory perception. Specifically, it explores the neural mechanisms of auditory global timing perception in the human brain.
This project uses neuroimaging (MRI, fMRI, ERP, EEG) and behavioral research paradigms (psychoacoustics).
