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.
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]
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]
This suggests a positive neuromodulatory action of CART on the effects of psychostimulants in rats. [18] CART is altered in the ventral tegmental area of cocaine overdose victims, and a mutation in the CART gene is associated with alcoholism. [19] By inhibiting the rewarding effects of cocaine, CART has a potential use in treating cocaine ...
Locomotor activity is a measure of animal behavior which is employed in scientific research. [1] [2]Hyperlocomotion, also known as locomotor hyperactivity, hyperactivity, or increased locomotor activity, is an effect of certain drugs in animals in which locomotor activity (locomotion) is increased. [3]
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 ...
San Diego sector Border Patrol agents announced the seizure of more than 80 pounds of cocaine in Temecula. The drugs were stashed inside an SUV's false dashboard, authorities said.
Cocaine also blocks the serotonin transporter and norepinephrine transporter, inhibiting reuptake of serotonin and norepinephrine from the synaptic cleft into the pre-synaptic axon terminal and increasing activation of serotonin receptors and norepinephrine receptors in the post-synaptic neuron, contributing to the mental and physical effects ...
