We tested a prediction that detection of distal threat would elicit activity in brain regions associated with value - based and complex decision making, such as the anterior cingulate and ventromedial prefrontal cortex (vmPFC), whereas proximal threat would engage low - level midbrain regions implicated in reflexive escape behavior (i.e., PAG).

The researchers did find that the older people had more activity in brain regions responsible for attentiveness, such as the posterior cingulate cortex.

In this way, they were able to use pulses of light on mice to stimulate theta - brainwave - like activity around the anterior cingulate cortex.

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.
