Steps to a neurochemistry of personality

Depue & Collins's (D&C's) work relies on extrapolation from data obtained t hrough studies in experimental animals, and needs support from studies of t he role of dopamine (DA) neurotransmission in human behaviour. Were we revi ew evidence from two sources: (1) studies of patients with Parkinson's dise ase and (2) positron emission tomography (PET) studies of DA neurotransmiss ion, which we believe lend support to Depue & Collins's theory, and which c an potentially form the basis for a true neurochemistry of personality.
