Fish Eats Food. Scientists Watch Fish's Thoughts
Ed Yong, Phenomena
A baby fish watches a tasty cell swimming in front of it. Neurons fire in its brain, and it recognises a potential meal. Its eyes converge, it beats its tail, and it heads in for the kill.
Trillions of baby fishes have enacted this little tableau for half a billion years, but this individual is special. It has been altered by a team of Japanese scientists so that its neurons give off a flash of light whenever they fire.
