Abstract EN
A visual-to-auditory sensory substitution device initially developed for the blind is known to allow visual-like perception through sequential exploratory strategies.
Here we used functional magnetic resonance imaging (fMRI) to test whether processing the location versus the orientation of simple (elementary) “visual” stimuli encoded into sounds using the device modulates the brain activity within the dorsal visual stream in the absence of sequential exploration of these stimuli.
Location and orientation detection with the device induced a similar recruitment of frontoparietal brain areas in blindfolded sighted subjects as the corresponding tasks using the same stimuli in the same subjects in vision.
We observed a similar preference of the right superior parietal lobule for spatial localization over orientation processing in both sensory modalities.
This provides evidence that the parietal cortex activation during the use of the prosthesis is task related and further indicates the multisensory recruitment of the dorsal visual pathway in spatial processing.
