A group of scientists in Korea and America has invented a device that may control neural circuits utilizing a tiny brain implant managed by a smartphone.
Researchers, publishing in Nature Biomedical Engineering, believe the device can speed up efforts to uncover brain diseases such as Parkinson’s, Alzheimer’s, addiction, depression, and ache.
The device, utilizing Lego-like replaceable drug cartridges and highly effective Bluetooth low-energy, can target specific neurons of interest using drug and light for prolonged periods.
“The wireless neural device allows chronic chemical and optical neuromodulation that has never been achieved before,” mentioned lead author Raza Qazi, a researcher with the Korea Advanced Institute of Science and Technology (KAIST) and University of Colorado Boulder.
Qazi stated this technology significantly overshadows standard methods utilized by neuroscientists, which normally contain rigid metal tubes and optical fibers to ship drugs and light. Other than limiting the subject’s movement as a result of physical connections with bulky tools, their relatively rigid structure causes a lesion in soft brain tissue over time, due to this fact making them not suitable for long-term implantation. Though some efforts have been put to partly mitigate adverse tissue response by incorporating soft probes and wireless platforms, the previous options had been limited by their inability to ship drugs for lengthy periods of time as well as their bulky and complex control setups.
