Now, a new study from the University of Michigan adds a new twist to dopamine's fun-loving reputation: pain.Using sophisticated brain-scanning and a carefully controlled way of inducing muscle pain, the researchers show that the brain's dopamine system is highly active while someone experiences pain -- and that this response varies between individuals in a way that relates directly to how the pain makes them feel.The chemicals themselves cannot determine their effect, which is controlled by the receptor they go to.Normally, neurotransmitter molecules are enclosed in vesicles, and a synaptic depolarization results in the opening of calcium ion channels, which releases them. When these transmitters are released through exocytosis, they disseminate across the synaptic divide and stick to receptors.
