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 ...
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 ...
These chemicals inhibit the action of DAT and, to a lesser extent, the other monoamine transporters, but their effects are mediated by separate mechanisms. Monoamine transporters are established targets for many pharmacological agents that affect brain function, including the psychostimulants cocaine and amphetamine. Cocaine and amphetamine ...
Axon terminals (also called terminal boutons, synaptic boutons, end-feet, or presynaptic terminals) are distal terminations of the branches of an axon. An axon, also called a nerve fiber, is a long, slender projection of a nerve cell that conducts electrical impulses called action potentials away from the neuron's cell body to transmit those ...
The effect of these structural changes on behavior is uncertain and studies have produced conflicting results. Two studies [18] [19] have shown that an increase in dendritic spine density due to cocaine exposure facilitates behavioral sensitization, while two other studies [20] [21] produce contradicting evidence.
How does pink cocaine affect someone? It can be hard to determine how the drug cocktail may affect someone after ingesting it. WebMD said this is due to several factors: the types of drugs mixed ...
Most people enter military service “with the fundamental sense that they are good people and that they are doing this for good purposes, on the side of freedom and country and God,” said Dr. Wayne Jonas, a military physician for 24 years and president and CEO of the Samueli Institute, a non-profit health research organization.
This receptor had been seen to modulate the rewarding effects of cocaine, and receptor antagonists had blocked the acute locomotor stimulating effect and lowered behavioral sensitization. Changes in the sigma 1 receptor have been shown to modulate dopamine release, so shifts in its expression can change the behavioral responses to cocaine with ...
