WHAT HAPPENS IN THE BRAIN: The colored areas in this brain highlight the parts involved in emotion.
The long green part is the hippocampus and is important in memory recall.
In your brain, they inflame the amygdala (increasing the intensity of sadness, fear, and anger) and block the hippocampus from laying down memory tracks.
If these chemicals continue for any length of time, the hippocampus shrinks and the amygdala enlarges. Parts of the cortex (the gray area on the outside that does most of your thinking) are also affected, including the VMPF (ventral medial prefrontal cortex), which controls emotions by calming the amygdala.
