>HHMI is applying techniques in synthetic biology to make these “steering” neurons sensitive to light by inserting genes similar to those naturally found in the eye. Yeah, I'm going to need to see a lot more information on what they mean by that. Which genes? What proteins do they code for? How is their transfection being targeted to only "steering" neurons? What proportion of their 'optrodes' successfully contact their target neuron? Among other questions... This sounds highly aspirational, not like an actual product or even a proof-of-concept.
