What are the effects of norepinephrine and dopamine ?

Catecholamines: Behavior is much more complex than neurotransmitter levels alone. But norepinephrine (ne) acts mainly in an area of your brainstem called the locus coeruleus. When released, ne triggers the stress response. Ne is also involved in pain, cognition, mood, emotions, movement and blood pressure. Dopamine is involved in regulating mood, pleasure, delusions, psychosis and drug abuse -- and more.
