Pinpointing a Pivotal Processor:

“Every known drug of abuse, a wide variety of neurotransmitters and therapeutic agents, all channel into a single protein that “integrates information from all over the brain and provides a meaningful physiological readout,” according to Nobel Laureate Paul Greengard.

Greengard, professor of neuroscience at Rockefeller University in New York, has shown that a 32-kilodalton protein, dopamine- and cAMP-regulated phosphoprotein (DARPP-32), is a pivotal molecule in virtually all dopamine-related activities.” BioMedNet [free registration required] [thanks, Brian!]
