Taking advantage of all the effort that's gone into the internet, telecommunications, etc., you can put optical fibers connected to lasers to activate -- in animal models, for example, in preclinical studies -- these neurons and see what they do.
se'n pot treure profit de tot l'esforç invertit en Internet, en les comunicacion, etc. i connectar fibres òptiques a làsers per tal d'activar, en models animals i en estudis pre-clínics, aquestes neurones i veure què fan.
