Dopamine receptors?

Post by deostroll » Wed Oct 08, 2008 3:03 pm

How did we find out that inside our brain's limbic system there are dopamine receptors? But why are the receptors there? How do you evolutionarily account for it?

Dopamine has functions in cognition and learning as well as other beneficial traits from an evolutionary point of view. Evolution would have favoured it and the emergence of a receptor for it I would think.
