They can similarly tell how many dots a person has been presented with, according to a report published online on September 24th in Current Biology, a Cell Press publication.These findings confirm the notion that numbers are encoded in the brain via detailed and specific activity patterns and open the door to more sophisticated exploration of humans' high-level numerical abilities. Although "number-tuned" neurons have been found in monkeys, scientists hadn't managed to get any farther than particular brain regions before now in humans.
