‘Mind Reading’ Technology Decodes Complex Thoughts

Researchers report they can use brain activation patterns to identify complex thoughts. Their findings suggest the building blocks for complex human thoughts are not word based, but formed by the brain's sub systems. The study provides evidence that the neural dimensions of concept representation are universal across people and languages.
