Rayleen Stacy April 24 2019 Neuro Psych 255 Connection Between Motivation and Dopamine Researchers have continued looking into just what dopamine actually does when re- leased, this section went into depth about dopamine and how it is attached to the feelings of do- ing whatever you can do obtain a certain outcome you want, not just wanting but seeking. Dopamine is directly linked to our reward prediction error, a researcher Salamone did a study with rats and placed a leveraged for them to press for when they felt like eating and a non pre- ferred food bowl next to it, some rats had the placebo and just went to get the food when they felt hungry. The rats who were injected with a dopamine antagonist in there nucleus accumbens still pressed the lever but those rats preferred the non preferred food already out. His study showed reward prediction played a huge role when it came to dopamine. The whole point was to basi- cally test if the rat still wanted the food after the learned association.

    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.
