Noninvasive Brain Control: New Light-Sensitive Protein Enables Simpler, More Powerful Optogenetics



Noninvasive Brain Control: New Light-Sensitive Protein Enables Simpler, More Powerful Optogenetics, Neurotechnology, Neuroscience
Optogenetics, a technology that allows scientists to control brain activity by shining light on neurons, relies on light-sensitive proteins that can suppress or stimulate electrical signals within cells. This technique requires a light source to be implanted in the brain, where it can reach the cells to be controlled. MIT engineers have now developed the first light-sensitive molecule that enables neurons to be silenced noninvasively, using a light source outside the skull. This makes it possible to do long-term studies without an implanted light source. The protein, known as Jaws, also allows a larger volume of tissue to be influenced at once…
