Scientists have invented a brain decoder that could read your inner thoughts

brainScientists have figured out how to read the words of our inner monologue, a finding that could help people who cannot physically speak to communicate with the world. Talking to yourself or having mindless internal thoughts is something which most of us can admit to. But imagine if we told you that someone could eavesdrop on your private thoughts? This sounds very creepy, but it’s exactly what scientists are working towards achieving.

When you hear someone speak, sound waves activate specific neurons that allow the brain to interpret the sounds as words. Now scientists have created an algorithm that does the same thing, but with brain activity instead of sound waves. To learn how to translate people’s thoughts, researchers from the University of California in the US looked at the brain activity of seven people undergoing epilepsy surgery. The participants were asked to first read aloud a short piece of text, then read it silently in their head.

While they read the text aloud, the team built a personal ‘decoder’ for each patient, by mapping which neurons were reacting to different aspects of speech. They made this map using Electrocorticographic (ECoG) readings of electrodes implanted in the patients. Once they’d worked out which brain patterns related to which words, they then used their decoder to try to read brain activity during silent reading, and found that it was able to translate several words that the volunteers were thinking.

  1. Made a very important ( revolutionary and unpublished ) discovery – invention-the1.first practical device for reading human thoughts, AChM; 2.аппарат для чтения мыслей человека, АЧМ; 3.human mind reading machine; 4.brain decoder; 5.brain decoding machine interface; 6.device for thoughts identification. I can not to publish my discovery and I invite partnership and need moral support. Thank you. Сурен Акопов. Email :
