optogeneticsA story from MedGadget highlights the continuing advances that optogenetics is making. The optogenetics procedure involves using light to stimulate genetically altered neurons. Until now, research efforts have been hampered by the need to tether laboratory test animals to fiber optic cables in order to deliver the light stimulus. Stanford University researchers have now developed an implant that can be powered wirelessly via microwave energy.

This latest news suggests that optogenetic techniques will continue to advance, so that optogenetics can be used broadly to study brain function and other physiological systems. The resulting knowledge will undoubtedly power the medical device design of the future.
