A Thought Moves Through a Fish’s Brain:

Japanese scientists captured it by using a probe sensitive to florescence, relying upon a particular gene called GCaMP that reacts to the presence of calcium ions by fluorescing brightly. Because calcium concentrations fluctuate when neurons fire, the florescent spot is the location of neuron activity in the fish’s brain. This was confirmed by the fact that the pattern above occurred after the researchers released a paramecium into the fish’s environment—and the particular brain areas activated matched the neurons that fired when the fish visually tracked a dot moving around in the same directions.
