Arvid Carlsson confirmed dopamine as a neurotransmitter and modulator the following year. Carlsson developed a method to actually measure dopamine levels in brain tissues, particularly in those parts of the brain important for movement. He showed that a decrease in dopamine levels brought on symptoms in animals similar to those seen in Parkinson’s patients and this opened the door to possibly managing the disease if these levels could be increased or supplemented.
