Why is the Localization of Neurotransmitters Important?
The localization of neurotransmitters is critical for understanding their function within different regions of the brain and other tissues. For instance, dopamine is primarily localized in the substantia nigra and plays a role in movement and reward pathways. Serotonin, found in the raphe nuclei, is essential for mood regulation. By studying their localization, researchers can better understand the physiological and pathological roles of these molecules.
