I was thinking about the details. We have good enough microscopes already resolution wise but to cut up a brain fine enough and picture it with existing electron microscopes would take ages, probably centuries with current tech so it needs a speed improvement more than anything. Also a 20nm scan could produce an awful lot of data ~ a billion TB which could be an issue even allowing for Moores law. Still there&#x27;s quite a lot of research money going it to this stuff.
