Scientists read monkeys’ inner thoughts

Scientists at Washington University in St. Louis who were decoding the activity of populations of neurons in the motor cortex discovered that they could tell how a monkey was planning to approach a reaching task. By chance the two monkeys chosen for the study had completely different cognitive styles. One was a hyperactive type, who kept jumping the gun, and the other was a smooth operator, who waited for the entire setup to be revealed before planning his next move. The difference is clearly visible in their decoded brain activity, allowing the scientists, in effect, to read their minds.
