Dual-Purpose Neural Probe Enables New Capabilities

Facebook X LinkedIn Email
HOUSTON, June 13, 2012 — A new device that combines light delivery with a tetrode into a single neural probe may offer new ways of studying small clusters of brain cells. Wei-Chuan Shih, a University of Houston Cullen College of Engineering assistant professor of electrical and computer engineering, said scientists generally must rely on two separate probes to study how neurons react to optical stimulation. The first probe delivers light to a specific area of the brain to stimulate cells, while the second records reactions of nearby neurons stimulated by the light probe at the single neuron level. The second...Read full article

    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
    tetrode
    An electron tube that has an anode, a cathode, a control electrode and another electrode (usually a screen grid).
