Psychology definition for Dopamine (DA) Hypothesis in normal everyday language, edited by psychologists, professors and leading students. Help us get better.
The hypothesis that dopamine is important for reward has been proposed in a number of forms, each of which has been challenged. Normally, rewarding stimuli such as food, water, lateral hypothalamic brain stimulation and several drugs of abuse become inef
At a high level of representation, this hypothesis is similar to long-standing theories of hemispheric differences, but differs from these by providing a single biological difference between hemispheres that influences both motor and prefrontal asymmetries. Specifically, I propose that a hemispheric ...
cannabis, and our ability to quantify D2 and D3 receptor availability in-vivo, here we propose to test the hypothesis that CU during early abstinence have altered dopaminergic responses (increased [11C]-(+)-PHNO displacement) to a validated psychosocial stress challenge (Pruessner et al, 2004)...

And the hypothesis there is that, as long as you're using anything that sort of pings your reward pathway, you're kind of setting yourself up for relapse. [01:01:49] Because all rewarding substances and behaviors work on the same final common pathway. They all release dopamine in the ...
In the current study, we tested this hypothesis using fast-scan cyclic voltammetry to monitor phasic DA signaling in the nucleus accumbens core of cocaine-pretreated (6 once-daily injections of 15 mg/kg, i.p.) and drug-naive rats during a test of cue-evoked incentive motivation for food...
Next, we tested whether spontaneous post-extinction reactivations of a multi-voxel activity pattern (MVP) in the vmPFC, elicited by the offset of the first five CS+ trials early in extinction, on day 2 predict extinction memory retrieval at test on day 3 (preregistered hypothesis 2). We ob...
Although he has thought about writing a popular-press book, he's not sure he really wants to go to the public and "debunk" the dopamine hypothesis of pleasure and reward. But if he ever does, one thing is for sure. "I can sum up all this work with one phrase, which would make a...
