<< a set of neurons trained to fire in unison could be reactivated as much as a day later if just one neuron in the network was stimulated. >>
AA << injected the mouse with a virus containing light-sensitive proteins engineered to reach specific brain cells. Once inside a cell, the proteins allowed researchers to remotely activate the neuron with light, as if switching on a TV >>
<< But then I saw the results and said "Holy moly, this whole thing is plastic". We're dealing with a plastic computer that's constantly learning and changing >> Rafael Yuste.
