Abstract
A neuroprosthetic system for substituting a sensory modality of a mammal by electrical stimulation of a region of the cerebral cortex corresponding to the neural modality to be substituted. The system includes at least one sensor for generating a sensed data feed by sensing a neural modality to be substituted, an electrode unit including a plurality of three-dimensional arrays of flexible electrode shafts for implantation of a region of the cerebral cortex, a rigid electrode support structure for guiding the flexible electrode shafts into the region of the cerebral cortex and for retraction after implantation, a driving unit for electrically driving the electrode, a recording unit, and a processing unit for analysing sensed data feed for providing stimulation patterns for electrically driving groups of electrical contacts of the electrode unit corresponding to subsets of locations in the region of the cerebral cortex, for substituting the sensory modality.
