The Focus on Neuroscience Box, "Emotions and the Brain," Described

The Focus on Neuroscience box, "Emotions and the Brain," described a PET scan study investigating brain activation when participants recalled different kinds of emotional memories. What were the results of this study?

A) No matter what emotion was experienced, a single brain area was activated, indicating that there is a single emotion center in the brain.
B) The hypothalamus was activated by memories involving positive emotions, and only the amygdala was activated by memories involving negative emotions.
C) Each of the emotions produced a different pattern of brain activation, indicating that each emotion involved distinct neural circuits in the brain.
D) The amygdala was activated by memories involving positive emotions, and only the hypothalamus was activated by memories involving negative emotions.
