Raphe nuclei, locus coeruleus

Serotonin is released from the ___________, while norepinephrine is released from the __________, and both traveling diffusely throughout the brain.

Metatrobic

The effects of the diffuse modulatory systems are largely mediated by the binding of neurotransmitters to

Reward

The mesocorticolimbic dopamine system is involved in the ______________ pathway, assigning value to certain behaviors.

SRRI

Tricyclic antidepressants differ from MAO inhibitors (MAOIs) because:
