Abstract: A visual prosthesis and methods of allowing a subject to view visual information from an artificial source are provided. The visual prosthesis has one or more electrodes operative to deliver electrical signals to a lateral geniculate nucleus of a mammal, a power supply operative to provide power to the electrodes, a visual information translator operatively connected to the electrode array, and a visual sensor operatively connected to the visual information translator. The visual prosthesis is operative to translate visual information into an electrical signal and transmit the electrical signal to electrodes to stimulate brain activity to recognize visual information.

Abstract: A chronic chamber microdrive (“CCMD”) for neural recording. In one implementation, a CCMD for neural recording from a target site of neural tissue exposed by an opening in a skull of a subject, includes: an outer cylinder, having a longitudinal axis, positioned within the opening and rotatable within the opening; an inner cylinder positioned within the outer cylinder, such that the longitudinal axis of the outer cylinder is within a circumference of the inner cylinder and the inner cylinder rotates within the rotatable outer cylinder; at least one fine leadscrew, positioned longitudinally in the inner cylinder; at least one electrode for neural recording, where at least one of said electrodes is coupled to a corresponding one of said fine leadscrews, where said electrodes are positioned horizontally by rotating the outer cylinder and separately rotating the inner cylinder, and where said electrodes are positioned vertically by rotating said fine leadscrews.

Abstract: Circuit supporting modules form a three-dimensional communication interconnect mesh. A first embodiment three-dimensional communication interconnect is a tetrahedral lattice having a regular, isotropic, three-dimensional topology in which each module connects to its four physically closest neighbors. The structure of the tetrahedral interconnect is isomorphic with a diamond lattice structure. In a second embodiment the interconnect is hexahedral. A characteristic of both is embodiments is that, although connections are made to plural other modules, the physical connections are made along the same direction.

Abstract: Circuit supporting modules form a three-dimensional communication interconnect mesh. Each module has fewer than six sets of connectors, preferably four. The preferred three-dimensional communication interconnect is a tetrahedral lattice having a regular, isotropic, three-dimensional topology in which each module connects to its four physically closest neighbors. The structure of the tetrahedral interconnect is isomorphic with a diamond lattice structure.
