When humans are torn between paying attention to two different things, it triggers a «conflict»
circuit in a brain region called the dorsal anterior cingulate cortex (dACC) which is part of a larger brain structure controlling rational thought and emotions.
Monkeys typically find other monkeys impossible to ignore, and this experiment was no exception: the monkeys often failed at the reward task because they looked at the faces, especially if the faces depicted emotion.When humans are torn between paying attention to two different things, it triggers a «conflict»
circuit in a brain region called the dorsal anterior cingulate cortex (dACC) which is part of a larger brain structure controlling rational thought and emotions.Using a tiny sensor implanted in the dACCs of the monkeys, Platt's group was able to measure the electrical activity of single neurons.
