I want to close on one story, which we think is another possibility, which is that maybe these molecules, if you can do ultraprecise control, can be used in the brain itself to make a new kind of prosthetic, an optical prosthetic.
Agora quero rematar cunha historia, que nos parece outra posibilidade e que, se acadamos  un control ultrapreciso, talvez permita usar  estas moléculas no propio cerebro para facer un novo tipo de prótese óptica.
