Fish Thoughts

In this seven second video, the brain activity of a fish is registered in real time. (Direct link to video)


The brain belongs to a zebrafish, and the neuronal activity is the response to a visual stimulus that resembles food for this species.

Gizmodo describes the flashes as "thought forming in the brain."

Calling it "thought" may be a bit exaggerated. I mean, how much do fish think when they see food? They're like me when I see a bowl of corn chips. Attack first, think later.

But still it's exciting to see mental activity visualized in this way.
