This Year, 3 days after my birthday, They did it. Japanese scientists have measured the Speed of Thought. Here is a video. This is a single thought captured in a Zebrafish’ brain. The video is beautiful – black background with a flourescent purple dot that you can see thought moving around in a very clear pattern.
Zebrafish is a clear see through fish. They measured increases in concentrations of Calcium IONS, which is what happens wherever a neuron is firing. They measured Directive-selective tectile neurons by sticking flouresscent die on a particular GENE that notices changes to their visual environment. The tectile part of the brain is where auditory and visual reflexes happen. They put a food source in. Right eye measured it, the ieft side of the brain had the activity. They created a new version of a tool called GCaMP7a which they was JUST made sensitive enough to capture something as tiny as little Calcium Ions.

for giving these people jobs so that they can come together and work on this project.
Watching a single thought travel in Real Time is something I knew I’d see someday, but just didn’t know when. I had the same experience when I saw my first video of an Electron: Something they told me, as a kid, we’d probably never be able to see. I knew ”They” were wrong. I knew someday we’d see it. I knew someday I’d see it. And They were wrong. And I was right. Vindicated after 30 years. An ancient dream fulfilled and exactly relevant to my project. -Kenneth Udut, Naples, FL USA 5/26/13
