Norepinephrine is another monoamine neurotransmitter that's important in arousal. It's derived from a brain region called the locus ceruleus and when you increase norepinephrine you have a number of typical physical phenomena. These include: increased heart rate, increased breathing and increased muscle tension. This is important from an evolutionary standpoint because it's part of the fight or flight response. Norepinephrine amps up a person's or an animal's ability to deal with a sudden stressful situation.
