P300 brain wave reading technology could possibly prevent terrorist attacks, such as the strike on New York's World Trade Center
Recently, 29 students from Northwestern University in Illinois planned a terrorist attack. Researchers from the university were subsequently able to learn details of the attack, even though the students never admitted to anything. How was this possible? Well, essentially, the researchers read the students’ minds. More specifically, they monitored their P300 brain waves – brief electrical patterns in the cortex, which occur when meaningful information is presented to someone with “guilty knowledge.” In this case, it was a mock planned attack, but the research team believe their process could be used to prevent the real thing.
