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 [194] due to its local anesthetic activity. Thousands of cocaine users are admitted to emergency ...
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 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.
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 ...
Cocaine's mechanism of action in the human brain includes the inhibition of dopamine reuptake, [49] which accounts for cocaine's addictive properties, as dopamine is the critical neurotransmitter for reward. However, cocaine is more active in the dopaminergic neurons of the ventral tegmental area than the substantia nigra.
An EEG is a noninvasive test that measures electrical activity in the brain using small metal discs called electrodes, which are attached to the scalp. These tests provide “quick and accurate ...
The dopamine transporter controls the dynamics of the neurotransmitter dopamine. This neurotransmitter controls many functions including movement, cognition and mood. Drugs such as cocaine and dimethocaine induce dopamine overflow by inhibiting dopamine transporters and thus creating a euphoric effect. [8]
2. Hollow Food Puzzles. As the name implies, these food puzzles are hollow, as they are meant to be filled with food. Their shape makes it challenging for dogs to extract the food, keeping them ...
