Angioedema: Angioedema is a severe swelling beneath the skin, especially of the face and the limbs. Sometimes, rashes also appear along with the swelling. Other symptoms are swelling of the eyes or eyelids and lips, stomach cramps, and difficulty breathing.
Emotions, like fear and love, are carried out by the limbic system, which is located in the temporal lobe. While the limbic system is made up of multiple parts of the brain, the center of emotional processing is the amygdala, which receives input from other brain functions, like memory and attention.
Prefrontal Cortex. The prefrontal cortex, located near the front of the head, is involved in decision making in response to emotions. The Canadian Institutes of Health Research states that the prefrontal cortex controls what decision a person makes when faced with an emotional reaction, and also regulates anxiety.
