In the past, people believed that mind reading would be something impossible to achieve. Well that belief has been proven as wrong. Scientists today have developed ways into in which they can guess what a person is thinking according to the chemical action going on in their brains. They tested this using a Magnetic Resonance Image o MRI. The subjects that were being tested had to lie in the machine and had to observe images such as the ones of a hammer or a house. Through the MRI they observed the chemical action and how it was more active in certain parts of the brain when a specific object was observed. The chemical activity was relatively the same among all subjects according to specific objects. Scientists could guess if a person was thinking of a hammer due to what parts of their brain lit up in the imaging. It is believed that this type of "mind reading" is only the beginning, but just the fact that through this they can already guess what you are thinking about is just amazing. In a couple of decades, I believe scientists will be able to decipher complete phrases and maybe even through easier processes, instead of having to use the MRI. Mind Reading will be an innovation for the world in many ways.
