An implicit premise in neuropsychopharmacology with regard to the psychological aspects is that all states of mind, including both normal and drug-induced altered states, and diseases involving mental or cognitive dysfunction, have a neurochemical basis at the fundamental level, and certain circuit pathways in the central nervous system at a higher level.
Ion channels located on the surface membrane of the neuron allows for an influx of sodium ions and outward movement of potassium ions during an action potential. Selectively blocking these ion channels will decrease the likelihood of an action potential to occur. The drug riluzole is a neuroprotective drug that blocks sodium ion channels. Since ...
Neuroscientists believe that drug addicts’ behavior is a direct correlation to some physiological change in their brain, caused by using drugs. This view believes there is a bodily function in the brain causing the addiction. This is brought on by a change in the brain caused by brain damage or adaptation from chronic drug use. [1] [2]
It's no secret that heroin, of the opioid drug family, is a dangerous epidemic in the United States. The number of U.S. deaths from heroin per year has spiked from roughly 3,000 in 2008 to roughly ...
Heroin, also known as diacetylmorphine and diamorphine among other names, [1] is a morphinan opioid substance synthesized from the dried latex of the opium poppy; it is mainly used as a recreational drug for its euphoric effects. Heroin is used medically in several countries to relieve pain, such as during childbirth or a heart attack, as well ...
The face of heroin abuse: When the data crunching was complete, the theories and experiments of the past were confirmed. There was indeed a change in the antibody population and a rise in ...
The first attempt to purify the receptor involved the use of a novel opioid antagonist called chlornaltrexamine that was demonstrated to bind to the opioid receptor. [10] Caruso later purified the detergent-extracted component of rat brain membrane that eluted with the specifically bound 3 H-chlornaltrexamine. [11]
In psychopharmacology, researchers are interested in any substance that crosses the blood–brain barrier and thus has an effect on behavior, mood, or cognition. Drugs are researched for their physiochemical properties, physical side effects, and psychological side effects.
