When Jason Shepherd first saw the structures under a microscope, he thought they looked like viruses. The problem was: he wasn’t studying viruses. Shepherd studies a gene called Arc which is active in neurons, and plays a vital role in the brain. A mouse that’s born without Arc can’t learn or form new long-term memories. If it finds some cheese in a maze, it will have completely forgotten the right route the next day.
