The drugs they studied included cocaine and a few others that have some similarities to cocaine in how they affect the brain. They trained the monkeys to give themselves these drugs through injections and observed their behavior. They wanted to see if the drugs had similar effects on the monkeys.
The neurotransmitter dopamine is a key candidate for explanation of reinforcing actions drugs. [6] [7] It's unclear to which extent NET is involved in the reinforcing actions of cocaine (an SNDRI). [8] Animal studies show evidence that inhibiting the SERT might reduce cocaine intake. [9]
Cocaine addiction results from complex molecular changes in the brain following multiple exposures to cocaine. [16] Dynorphins have been shown to be an important part of this process. Although a single exposure to cocaine does not affect brain dynorphin levels, repeated exposures to the drug increases dynorphin concentrations in the striatum ...
Cocaine is a non-selective, competitive inhibitor of monoamine transporters, sharing a similar mechanism with that of methylphenidate. Cocaine interacts with DAT, SERT, and NET, although the behavioral and reinforcing effects of cocaine depend on its inhibition of DAT and the increase in extracellular dopamine. [1]
Animal studies of the reinforcing and cocaine-like effects of dopamine releasing agents (DRAs) with varying capacities to release norepinephrine and serotonin in rodents and monkeys have suggested that in contrast to the case of serotonin release, which inhibits the reinforcing and stimulant-like effects of these agents, norepinephrine release ...
Cocaine- and amphetamine-regulated transcript, also known as CART, is a neuropeptide protein that in humans is encoded by the CARTPT gene. [ 1 ] [ 2 ] CART appears to have roles in reward, feeding, and stress, [ 3 ] and it has the functional properties of an endogenous psychostimulant .
Cocaine is a relatively "balanced" inhibitor, although facilitation of dopaminergic neurotransmission is what has been linked to the reinforcing and addictive effects. In addition, cocaine has some serious limitations in terms of its cardiotoxicity [188] due to its local anesthetic activity. Thousands of cocaine users are admitted to emergency ...
Cocaine (from French cocaïne, from Spanish coca, ultimately from Quechua kúka) [13] is a tropane alkaloid that acts as a central nervous system stimulant.As an extract, it is mainly used recreationally and often illegally for its euphoric and rewarding effects.
