The human brain is programmed to ensure the repetition of such life-sustaining acts by registering pleasure or reward in association to these activities. Upon the activation of this reward circuit every time, the brain registers its importance and the need to remember it, encouraging us to do it...
The inhibitory effects ofsuch drugs on a specific dopamine-stimulated adenylate cyclase in the brain have provided valuable support for this hypothesis.Leslie L. IversenTrends in Biochemical SciencesIversen, L. (1976). Dopamine in the brain and its possible role in madness....
If your doctor prescribes dopamine, watch for these side effects: Irregular heartbeat Faster heart rate Trouble breathing Chest pain Nausea and vomiting Headache Because many drugs interact with it, it’s important that your doctor knows all the medications you take. ...
The effects of dopamine and its antagonists on directional delay-period activity of prefrontal neurons in monkeys during an oculomotor delayed-response task. To examine the role of dopamine receptors in the memory field of neurons for visuospatial working memory in the prefrontal cortex (PFC), dopami...

variants. Dopamine is produced in several areas of the brain, including the substantia nigra and the ventral tegmental area. Dopamine is also a neurohormone released by the hypothalamus. Its main function as a hormone is to inhibit the release of prolactin from the anterior lobe of the ...
It has a long history of use for a wide variety of brain-related disorders such as memory loss, poor concentration, mental confusion, depression, and anxiety. But recently, ginkgo has fallen out of favor since not all of its claims as a memory enhancer have held up to scientific scrutiny ...
