    摘要: Certain aspects of the present disclosure are directed to a method of applying infrared neural stimulation (INS) to the central nervous system (CNS) of a target. The methods includes applying a pulsed infrared laser at a stimulation site in the CNS; and evoking responses from a region of interest of the CNS that is at or adjacent to the stimulation site by the pulsed infrared laser. In the method, the pulsed infrared laser penetrates a predetermined penetration depth of the stimulation site. Certain aspects of the present disclosure are directed to an apparatus for applying INS to the CNS of a target. The apparatus includes a generator generating a pulsed infrared laser, which penetrates a predetermined penetration depth of a stimulation site to evoke a response from the CNS, and an optical medium adapted for delivering the pulsed infrared laser at the stimulation site of the CNS.

    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: Optical spectroscopy for brain tumor demarcation was investigated in this study. Fluorescence and diffuse reflectance spectra were measured from normal and tumorous human brain tissues in vitro. A fluorescence peak was consistently observed around 460 nm (±10 nm) emission from both normal and tumorous brain tissues using 337 nm excitation. Intensity of this fluorescence peak (F460) from normal brain tissues was greater than that from primary brain tumorous tissues. In addition, diffuse reflectance (Rd) between 650 nm and 800 nm from white matter was significantly stronger than that from primary and secondary brain tumors. A good separation between gray matter and brain tumors was found using the ratio of F460 and Rd at 400 nm-600 nm. Two empirical discrimination algorithms based on F (400 nm-600 nm), Rd (600 nm-800 nm), and F (400 nm-600 nm)/Rd (400 nm-600 nm) were developed. These algorithms yielded an average sensitivity and specificity of 96% and 93%, respectively.
