Positron Emission Tomography PET scanning and functional MRI studies have shown that some emotions are more likely to be associated with different regions of limbic system activity than other emotions.
Happiness activates several areas of the brain, including the right frontal cortex, the precuneus, the left amygdala, and the left insula. Fear activates the bilateral amygdala, the hypothalamus and areas of the left frontal cortex. Sadness is associated with increased activity of the right occipital lobe, the left insula, the left thalamus the amygdala and the hippocampus.
The hippocampus is strongly linked with memory, and it makes sense that awareness of certain memories is associated with feeling sad. Sadness has been studied more than the other emotions because depression may last for a long time; the effects of antidepressants can be measured based on improved symptoms. Disgust is an interesting feeling that is often associated with avoidance. This emotion that is associated with activation and connections between the left amygdala, the left inferior frontal cortex, and the insular cortex.
Anger is an important emotion that many people, adults and children alike, try to control. Anger is associated with activation of the right hippocampus, the amygdala, both sides of the prefrontal cortex and the insular cortex. Download the pdf. Download printable poster.
