Research

Distributed representational systems like the human brain require some kind of binding mechanism to integrate information about the different features of a given to-be-represented event. Previous studies have revealed behavioral effects of feature binding in perception, action planning, and across perception and action. The current project investigates the functional and neurophysiological basis of these binding phenomena by analyzing the after-effects of the co-occurrence of two or more features: if the co-occurrence of two features X and Y does indeed create a binding between their neural codes, a subsequent encounter of X should activate the neural codes of Y even in the absence of it. Using fMRI, this rationale will be applied to investigate the integration of visual features, visual and auditory features, and sensorimotor integration in young and elderly subjects.
