Workflow from Scientific Research

In the first experiment, the neural correlates of a full audiovisual (AV) stimulus were studied in a sample of TD participants to examine how the brain processes multisensory information. In a second experiment, two unimodal versions of the same movie (that is, visual only (V) and auditory only (A)) were presented and the similarity across visually and auditory-evoked brain responses (A versus V) was assessed in two samples of TD participants. In a third experiment, we tested the role of audiovisual experience for the emergence of these shared neural representations by measuring the similarity of brain responses elicited across congenitally SD individuals (that is, blind and deaf participants).
