«The pattern of
activity in a
brain region involved
in spatial learning
in the virtual world is completely
different than when it processes
activity in the real world,» said Mayank Mehta, a UCLA professor of physics, neurology and neurobiology
in the UCLA College and the study's senior author.
Before and after experiencing this stress, Dzirasa and postdoctoral fellow Rainbo Hultman measured
brain activity in seven
different brain regions that have been linked to depression, including the prefrontal cortex, the amygdala and the hippocampus.
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.

brain activity.
