Abstract: In exemplary implementations of this present invention, a supercapacitor-based electronic device delivers high currents to an array of implantable light sources or electrodes. The device receives wireless power from an external transmit coil and receives control signals from either an onboard computer or external wireless data telemetry.

Abstract: In exemplary implementations of this invention, high-throughput screening of a mammalian brain is performed to locate neural circuit targets of interest. A variety of search patterns may be used for this neural screening, including (a) iterative subdivision, (b) serial search, and (c) combinatorial. To perform this neural screening, an array of optical fibers (or an array of waveguides) is inserted into the brain. Alternately, the array is positioned adjacent to the brain. Each fiber or waveguide in the array is coupled to a light source (LED or laser). The brain has been previously sensitized to light, using genetically encoded optical neural control reagents, which are delivered either using viruses or via transgenic means. In the screening, the array is used to optically perturb the brain. For example, the neurons of the brain may be activated by one color of light, and/or silenced by another color of light.

Abstract: According to principles of this invention, the photoelectrochemical effect (“PE effect”) may be greatly reduced or eliminated, even when an electrode is immersed in an electrolyte and exposed to light, by using a transparent conductor to record electrical activity. Thus, an electrode with a clear conductor may be used to accurately record electrical activity of neurons and other cells that are exposed to light in vivo or in vitro. Such an electrode eliminates or greatly reduces the artifacts that would otherwise be caused by light due to the PE effect.

Abstract: This invention may be implemented as a microstructure probe for delivering light of variable color and/or power, via a set of integrated lightguides, from an optical source (or set of sources) to regions spatially arranged 3-dimensionally, with a length scale of microns to millimeters. In exemplary embodiments of this invention, a microstructure probe comprises many lightguides and is adapted to be inserted into neural or other tissue. The lightguides run in parallel along at least a portion of the axis of the probe. The probe may deliver light to many points along the axis of insertion of the probe. This invention may be implemented as an array of two or more such probes (each of which comprises multiple lightguides). This array may be used to deliver light to neural tissue in a complex 3D pattern.

Abstract: Various systems and methods are implemented for controlling stimulus of a cell. One such method is implemented for optical stimulation of a cell expressing an NpHR ion pump. The method includes the step of providing a sequence of stimuli to the cell. Each stimulus increases the probability of depolarization events occurring in the cell. Light is provided to the cell to activate the expressed NpHR ion pump, thereby decreasing the probability of depolarization events occurring in the cell.

Abstract: The invention pertains to a surgical system. In an embodiment, the system comprises one or more sensors operably responsive to physical boundary limitations of an operating field. Furthermore, the one or more sensors provide information regarding the physical boundary limitations of the operating field. In another embodiment, the system comprises a surgical instrument that is configured to respond to the information by either activation or inactivation. In another aspect the invention includes generating an anatomical image or anatomic positional reference data. Additionally, the method includes creating haptic feedback signals based at least partly on the anatomical image or anatomic positional reference data, and determining a position or orientation of a surgical instrument. Furthermore the method includes activating or inactivating the surgical instrument based at least partly on the haptic feedback signals.
