nervous asf
The part of the brain that contains dopaminergic reward centres.
What is the limbic system or limbic cortex?
This substance is abused by 14.4% of Canadians annually.
What is alcohol?
This stimulant has the lowest abuse potential of any stimulant drug.
What is caffeine?
These are the receptors that become blocked by caffeine, resulting in a decrease in GABAergic dopamine inhibition.
What are adenosine receptors?
Taking these drugs can result in excess electrolyte and water depletion, leading to heart and kidney problems.
What are diuretics?
A neurological property where the connections between neurons are constantly being reshaped and reestablished, especially throughout growth and development.
What is neuroplasticity?
This theory states that the driving factor of drug addiction is an increase in activity in the dopaminergic reward pathways of the cerebrum.
What is the dopamine hypothesis?
This stimulant causes changes to the nasal mucosa.
What is cocaine?
The reuptake of this neurotransmitter, along with dopamine, is inhibited by cocaine.
What is serotonin?
These drugs block gonadotrophic releasing hormone and may cause low sperm count if used chronically.
What are anabolic steroids?
A class of neurotransmitters which includes dopamine and norepinephrine.
What are catecholamines?
What are hallucinogens?
Using this drug while pregnant increases the change of low birthweight and preterm labour due to low oxygen transfer to the fetus.
What is nicotine?
This stimulant drug competes with dopamine and norepinephrine for space in presynaptic vesicles.
What are amphetamines?
These are reportedly taken by ski jumpers to reduce anxiety before a competition.
What are benzodiazepines?
Two types of cholinergic receptors.
What are nicotinic and muscarinic receptors?
A measure of the tendency of a drug to cause dependence and addiction. May vary depending on drug used and individual characteristics.
What is dependence liability?
This drug is administered to patients with ADHD and narcolepsy.
What is Ritalin (methylphenidate)?
The effects that come from the activation of these receptors are similar to those produced by acetylcholine.
What are nicotinic receptors?
If an athlete stops administration of this performance enhancer 48 hours before competition, it is nearly impossible to detect.
What is human growth hormone (hGH)?
These are the three main classes of opioid peptides.
What are enkephalins, endorphins, and dynorphins?
A CNS disease that is caused by repeated consumption or chronic use of a substance.
What is substance dependence?
The active metabolite formed when alcohol is consumed concurrently with cocaine.
What is cocaethylene?
This protein is what allows amphetamines to take up space in presynaptic vesicles.
What is the vesicular monoamine transporter (VMAT)?
This performance enhancer can be detected by measuring hematocrit levels.
What is erythropoietin (EPO)?
