Optogenetics Device Offers Targeted Control of Light to Neurons

Facebook X LinkedIn Email
A University of Arizona research team has developed a wireless, battery-free method for controlling the intensity and frequency of light that is delivered to neurons in the brain. The miniature device for optogenetics can be fully implanted under the scalp and allows researchers to independently stimulate multiple locations in the brain of the same subject. Wireless and battery-free implant with advanced control over targeted neuron groups. Courtesy of Philipp Gutruf. The researchers said that previously developed ultrasmall, implantable devices for optogenetic neuromodulation were...Read full article

    optoelectronics
    Optoelectronics is a branch of electronics that focuses on the study and application of devices and systems that use light and its interactions with different materials. The term "optoelectronics" is a combination of "optics" and "electronics," reflecting the interdisciplinary nature of this field. Optoelectronic devices convert electrical signals into optical signals or vice versa, making them crucial in various technologies. Some key components and applications of optoelectronics include: ...
    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...
