Microimplant Controls Nerve Cells with a Laser

Facebook X LinkedIn Email
FREIBURG, Germany, and BASEL, Switzerland, Jan. 31, 2013 — A microimplant that can genetically modify specific nerve cells, control them with light stimuli and measure their activity simultaneously could pave the way for completely new experiments in neurobiology. In optogenetics, genes from certain species of algae are inserted into the genome of another organism, for instance a mouse, and when shined with a laser light, provide electrically charged particles in a nerve cell’s membrane that can allow neuroscientists to control the neural activity. Scientists from the University of Freiburg have built a microimplant that uses a...Read full article

    optogenetics
    A discipline that combines optics and genetics to enable the use of light to stimulate and control cells in living tissue, typically neurons, which have been genetically modified to respond to light. Only the cells that have been modified to include light-sensitive proteins will be under control of the light. The ability to selectively target cells gives researchers precise control. Using light to control the excitation, inhibition and signaling pathways of specific cells or groups of...
