The activation of a dopamine (DA) transmitter would be the same for that transmitter and any subtype (D1, D2, D3, etc.) A. In other words, the brain/drug cannot distinguish between subtypes of the same transmitter and therefore affects all of them equally because it is non- selective SSRI -selective serotonin reuptake inhibitor A. Reuptake blockade (of a transmitter) -when you want a drug to affect only a certain area Ex. Dopamine -therefore dopamine levels will rise if it is blocked -and will rise everywhere in the brain and the body i.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
