Multiplexed dopamine neurons predominate in the ventral midbrain of young macaques

Dopamine (DA) is important in many fundamental behaviors, including positive and negative reinforcement, incentive salience, and decision-making. This behavioral diversity is now known to be due, in part, to neurotransmitter diversity, based on rodent models. To address DA neuron transmitter properties in higher species, we examined the ventral midbrain in 5 young macaques (3 male, 2 females, 3-6 years) using RNAscope in situ hybridization for tyrosine hydroxylase (TH), vesicular glutamate...
