The picture above I found in an article in the New Scientist magazine . Brain scanning technology can now extract information directly from the brain: In the following experiment the subject reads the word "neuron" at the top, and software working with the brain scan images reconstructes the words below. This allows this new technology to penetrate into a human mind and read information in it. Quoting this article "(the creation of this technology) raises the prospect of "neural marketing", where advertisers might one day be able to read the thoughts of passers by and use the results to target adverts."
