A major question in the domain of sensory substitution is to understand the kind of percept generated by sensory substitution devices: is it similar to the one generated by a natural sensory modality (visual, tacile, auditory) or is it a totally new kind of perception? According to the sensory substitution theory, perceptual processing related to these substitutive stimuli should result in a visual-like perception. The main tasks of this project constists in analyzing: (a) the ongoing brain changes and (b) the links between sensory and congnitive brain representations, due to the utilization of a perceptual modality that is totally artificial and new to the subjects. To attain this objective, experimental psychology, neuroimaging and biomedical engineering techniques for sensory processing will be implemented.
The SenSub collaboration consisted of the following groups:
