Dopamine is one of the most well - known neurotransmitter. It is most widely known as the neurotransmitter that causes pleasure but is also causes motivation, movement as well as reinforcement of behavior. At MIT researchers used a specialized MRI sensor to measure the results and the effect of dopamine not only in one location in the brain but instead all across the brain. Using the new technique, the results showed that dopamine is exerted most in 2 regions of the brain cortex. The 2 regions of the cortex are the motor cortex and the insular cortex. The motor cortex control movement. While the insular cortex controls many cognitive functions and brain states. This includes physical and emotional states. This study can have many long-term effects. According to Alan Jasanoff an MIT professor of biological engineering, brain and cognitive sciences, and nuclear science and engineering. Jasanoff talks about the long-term effects saying “Our results could lead to biomarkers that could be seen in fMRI data, and these correlates of dopaminergic function could be useful for analyzing animal and human fMRI.” This shows how dopamine can be used to analyze animal and human fMRI’s. This could lead to important discoveries about the brain.
