At the National Institute of Genetics in Japan have been devoted recently to try to capture in a video which would be a thought taking shape in a brain. Although at first it may seem almost mystical in reality it is an animation showing how neurons are being activated as a thought occurs in the brain of a zebra fish .
The thinking in question is identified and is quite primary. Basically put something that looks like fish food nearby and captured the instant you saw, possibly wondering if that was floating around food or not.
To get impregnated zebrafish brain with a fluorescent substance that activates when there is some kind of neural activity. Then they recorded the video you can see a little further down in this article.
The basic idea of this experiment is to learn about the neural circuits and how neurons are activated, but the second part is more disturbing. They could create a database containing all activating neural circuits in the zebrafish in different circumstances. Then, glancing at the brain of this fish could get to know what he's thinking every time you submit a neuronal firing pattern determined. The next logical step and know what is applied to humans so that someday someone can know everything that you think with a simple brain scan.
