What's in a thought? When it comes to the zebrafish, now you can see for yourself. For the first time, Japanese researchers have captured video of thoughts moving through a zebrafish's brain.
By genetically modifying a transparent zebrafish larvae to create a glow in reaction to calcium ions--which skyrocket during neuron activity--scientists could track the regions in the fish's brain activated by the thought process.
Researchers released a paramecium, a single-celled zebrafish food source shaped like a grain of rice, and watched the glowing neurological response from the fish. As the paramecium moves from right to left, the zebrafish's thoughts bounce from left to right.
This research could lead to better psychiatric medications, according to Koichi Kawakami, one of the co-authors of the paper in Current Biology. Plus, there's always the possibility of thought detection: "In the future, we can interpret an animal's behavior, including learning and memory, fear, joy, or anger, based on the activity of particular combinations of neurons," he said.
How about we just keep watching the glowing fish?
We are going to see a lot more biology medical science in the future from the little Zebra fish.
This is amazing.
You can see the left side of his brain activates when food is on the right side and vice-versa.
How do we know what the fish thinks about what it sees? It is assume he thinks its food.
All I know is I see activity in the brain in relationship to external movement for the fish.
The fish could be just having bad thoughts about bad sushi he ate the other day, for all we know,lol.
