Scientists capture video of a thought being formed in a brain



For the first time, Japanese scientists captured video of a thought being formed, and it looks pretty much like miniature lightning tracing its way through a meshed structure of neurons:

Of course, this is not a human brain that mad scientists exported from a skull and sliced up in the pursuit of scientific information. Rather, this is a the brain of a baby zebrafish — and it wasn’t even harmed in the experiment. Researchers chose this creature because in their embryonic and larval states, zebrafish have the wonderful property of being almost completely transparent.

The scientists dosed the baby fish with fluorescencing agents that glow when neurons are activated, then induced a paramecium — a tiny protozoa about 200 micrometers in length — to swim by, causing the zebrafish to perk up and think about a snack.

That caused neural impulses to be fired off in the zebrafish’s “optic tectum,” a region of the midbrain. Which the Japanese researchers then captured video of, and, naturally, uploaded to YouTube, solving once and for all the perplexing question: what do fish think of?

Mostly, it appears, lunch. Which is not too different from humans, perhaps.

1. AND we know what that little zebrafish is thinking:

"Hope I don't end up as sushi"

2. Hmm..this could have nasty implications...

ie: Mind control
or mind fucking

I am still amazed that our brains are capable of such complex thoughts, not to mention self awareness.

14. You shouldn't be worried about this technology.

This was possible because zebrafish see-through heads.

If you're worried about people reading minds with technology, I can tell you that it's already been done:

to give you just a few links.

3. Now the next step.....

is to compare the thought of a right wing brain; to a normal progressive one. We will see evidence of lack of activity in the right wing brain; and normal functioning in the progressive brain.

4. If they had picked a Teapublican for this study...

For the first time, Japanese scientists captured video of a thought being formed, and it looks pretty much like miniature lightning tracing its way through a meshed structure of neurons.

The "miniature lightning" would turn out to be a night light...

12. And yet...

The odds are that the owner of the progressive brain will still -- against ALL reason -- allow the owner of the right wing brain to get their way every time.

6. Watching that made me feel a little ill.

Did anyone else react in that way?

I'm not joking.

Interesting. Are you unusually sensitive?

8. Zebrafish?

 

Perhaps the scientists should have started with something vastly more simple, such as the brain of a right-wing human.

We all saw this already in Fantastic Voyage (1966), didn't we?
