    摘要: An apparatus and method for stimulating animal tissue (for example to trigger a nerve action potential (NAP) signal in a human patient) by application of both electrical and optical signals for treatment and diagnosis purposes. The application of an electrical signal before or simultaneously to the application of a NAP-triggering optical signal allows the use of a lower amount of optical power or energy than would otherwise be needed if an optical signal alone was used for the same purpose and effectiveness. The application of the electrical signal may precondition the nerve tissue such that a lower-power optical signal can be used to trigger the desired NAP, which otherwise would take a higher-power optical signal were the electric signal not applied. Some embodiments include an implanted nerve interface having a plurality of closely spaced electrodes placed transversely and/or longitudinally to the nerve and a plurality of optical emitters.

    摘要: A method for detecting death process of a cell or tissue of a living subject. In one embodiment, the method includes the steps of illuminating the cell or tissue of the living subject with a coherent light, collecting fluorescent light returned from the illuminated cell or tissue of the living subject, identifying a NAD(P)H peak of a spectrum of the collected fluorescent light with a wavelength, λpeak, and obtaining the intensity of the NAD(P)H peak of the spectrum of the collected fluorescent light substantially corresponding to the wavelength λpeak. These steps are repeated at sequential stages until the intensity of the NAD(P)H peak of the spectrum at a current stage is less than the intensity of the NAD(P)H peak of the spectrum at an earlier stage immediately prior to the current stage so as to detect death process of the cell of the living subject at the current stage using the intensity of the NAD(P)H peak of the spectrum.

    摘要: The present invention provides methods of directly stimulating neural tissue with optical energy. By stimulating neural tissue at wavelengths, laser pulses, and spot sizes disclosed herein, nerve stimulation may be used to uniquely stimulate neural tissue in way not afforded by other means of stimulation. It can allow basic scientists to study the properties of individual neurons or populations of neurons without piercing tissue with fragile microelectrodes. Furthermore, responses of neural tissue can be studied in a pure fashion without contamination by electrical artifact commonly seen with electrical stimulation. With respect to clinical uses, optical stimulation can be used to map function in subsections of peripheral nerves as an aid to operative repair. Finally, stimulation with optical energy does not require physical contact with the nerve which may be an advantage clinically when physical manipulation of neural tissue is not desired.
