Self-tracking, wireless and implantable device may offer greater possibilities for optogenetic research

Written by Courtney Johnson

A newly engineered neuron-activating device intended for subcutaneous implantation and capable of wireless control in mice has been developed by researchers at Stanford University (CA, USA). The device, which was presented recently in Nature Methods, enables neural stimulation and modulation of nerves by a process known as optogenetics, in which nerves are engineered to contain light-sensitive proteins. The new technology may provide an opportunity to expand the scope of future investigations into neural modulation by allowing optogenetic studies of naturally behaving animals. Optogenetics has been used to examine a range of topics within neurology, such as how to relieve tremors...
