Neurons encode modality, intensity, location, and timing in different manners depending on the type of neuron involved. For a simple stimulus response reflex, or a central pattern generator, there are three types of neurons involved – from stimulus to response. Introduction DA is the dominant catecholamine neurotransmitter in the mammalian brain. DA has been widely implicated in controlling numerous functions including, but not limited to, motor activity, cognition, emotion, positive reinforcement, hunger regulation, and endocrine function. This catecholamine has diverse functions in the periphery as well, including, gastrointestinal motility, vascular Figure 6 – DA receptors and their respective influences on signaling pathways. Does coactivation = colocalization?   According to Deng, 10% of striatal projections to the GPe had D1 and D2 colocalized, and 40% of striato-GPi/SNr neurons had D1 and D2 colocalized. But the
