Monoamine transporters are established targets for many pharmacological agents that affect brain function, including the psychostimulants cocaine and amphetamine. Cocaine and amphetamine employ different mechanisms that both result in an increase in extracellular monoamines by decreasing reuptake.
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.
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 ...
Axonal transport, also called axoplasmic transport or axoplasmic flow, is a cellular process responsible for movement of mitochondria, lipids, synaptic vesicles, proteins, and other organelles to and from a neuron's cell body, through the cytoplasm of its axon called the axoplasm. [1]
Texas ranks 45th for cocaine use in the U.S. The ranking is based on the highest to lowest percentage of adults over 18 that say they have used cocaine over the past year across each state ...
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 ...
Traces of the powerful synthetic opioid was first found inside a dead dolphin that was floating in the gulf water when it was then examined by researchers from Texas A&M-Corpus Christi in Sept. 2020.
