Dopamine has been seen as crucial tolearning, but what does dopamine do? When the brain is presented with an unexpected reward, dopamine increases, prompting the limbic reward system to take note and remember how to repeat such a positive experience. On the other hand, negative encounters hamper...
Histamine, acting onhistamine H1 receptors, can potentiate dopamine receptors to become more sensitive to dopamine [11]. Therefore, people with higher histamine levels or stronger H1 receptor activation may feel more pleasure from dopamine. Dopamine does not mediate pleasure. It is known that the lo...
Among the neurotransmitters involved in addiction, dopamine (DA) is clearly the best known. The critical role of DA in addiction is supported by converging evidence that has been accumulated in the last 40 years. In the present review, first we describe the dopaminergic system in terms of conne...
Focalin contains dexmethylphenidate whereas Adderall contains a mixture of amphetamine salts (MAS). Both have a high potential for abuse and dependence, although the risk may be perceived as higher with Adderall because it is more popular; however, this does not mean Focalin is less likely to ca...
Adrenaline: Adrenaline or epinephrine is also called a stress hormone because the adrenal medulla secretes it during stressed conditions. This gland is located above the kidney. The receptors of epinephrine hormone are called adrenergic receptor...
(1) amphetamine disruption of LI is indeed a function of calcium-dependant dopamine release in the NAC at the time of conditioning; (2) other drugs acting on LI via changes in dopamine transmission act at the same locus; (3) the disruptive effect of indirect dopamine agonists on LI can ...
Adderall is a dextroamphetamine/amphetamine combination medication used to treat attention deficit hyperactivity disorder. It works by changing the amounts of certain natural substances in the brain. It is classified as a Schedule II controlled substance because it has a high potential for abuse. ...
