  • Patent number: 8652185
    Abstract: Disclosed is an apparatus for stimulating the brain and measuring the light induced neuronal activity including a signal application unit which applies a signal to a living tissue to stimulate the neuronal cells in the living tissue; an electrode unit which detects an electrophysiological signal of the neuronal cell in response to the signal; and an insulation unit which controls an impedance of the electrode unit. The signal application unit is formed integrally with the electrode unit, so that the site where the signal is applied to the living tissue is approximated to the site where the response to the stimulation is measured.

  • Patent number: 8348986
    Abstract: A photostimulation apparatus may include: a membrane for insertion into a living body; and at least one cell disposed on the membrane. Each cell may include a first light source for irradiating light to a photosensitive material in the living body. Further, a photostimulation apparatus may include: a membrane for insertion into a living body; and at least one first light source disposed on the membrane for irradiating light to a photosensitive material in the living body. Since the photostimulation apparatus is placed on the surface of cortex or dura, it may minimize damage of the brain tissue and may activate and/or inhibit a large area simultaneously using light.

  • Publication number: 20100241006
    Abstract: Disclosed embodiments relate to an apparatus for detecting brain conditions. The apparatus for detecting brain conditions may include: a layer which is located adjacent to the brain of a living body; a light source which is formed on the layer and irradiates light to the brain; and an optical sensor which is formed on the layer adjacent to the light source and detects the light scattered from the brain. Since detection is possible at a location relatively adjacent to the brain, the apparatus for detecting brain conditions may improve accuracy and reliability of detection. The apparatus for detecting brain conditions may be used to detect brain conditions such as cerebral oxygenation, cerebral blood volume, cerebral blood flow, etc. or to monitor brain activities, or to diagnose and/or localize the disease foci in case of neurovascular disease such as stroke including hemorrhage or bleeding, into or around the brain or brain tumors or epilepsy, etc.

  • Publication number: 20100086491
    Abstract: The present invention relates to a capsule used for measuring flow information using X-rays and a method of measuring flow information using the same. More particularly, the present invention relates to a capsule used for measuring flow information using X-rays including a biocompatible polymer, an organic contrast agent or deionized water, and a cross-linking agent, wherein the biocompatible polymer that is cross-linked with the cross-linking agent is filled with an organic contrast agent or is empty. Thereby, it is possible to remarkably increase the image-capturing time, to accurately and quantitatively measure the blood flow, and to gain accurate in vivo flow information.

  • Patent number: 7227621
    Abstract: A system for measuring flow information of a fluid, the system includes a light emission control unit for passing an X-ray through a specimen only at desired moments; a scintillator installed on an axis of a beam to convert an X-ray wavelength flow image, which is generated while the X-ray passes through the specimen, into a visible wavelength flow image; and a recording device for acquiring a flow image focused on the scintillator. The system may further include a synchronization unit for synchronizing the recording device with the light emission control unit to acquire two or more flow images at a predetermined interval using the recording device; and a PIV velocity field measurement unit for extracting quantitative flow information from the two or more flow images acquired by the recording device.
