With the usual crummy standards of science reporting, this leaves me more confused than when I started. Is Arc in the human genome or not? If it's not, then where does it come from? And if it is, why do neighboring neurons die if they do not get a transmission of the encapsulated Arc RNA? Can't they build it themselves?
