Does trazodone increase dopamine?
If trazodone does impact dopamine, it does so very slightly, and such effect is negligible. So, I would say no. Trazodone is an agonist for the 5-HT (serotonin)-1A receptor (similar to buspirone, where it acts to reduce anxiety). It also antagonizes (blocks) the following receptor subtypes: - 5-HT 2A, 2B, and 2C - alpha-1 and alpha-2 adrenergic receptors - histamine-1 receptor
What is receptor desensitisation?
Receptors generate a cellular response upon binding their specific ligand. This response can vary in magnitude. Desensitisation is a phenomenon in which activation of a receptor can reduce the magnitude of the response if it is subsequently activated again. Usually the longer a receptor is activated for the greater the desensitisation will be. There are 3 general mechanisms as to how desensitisation occurs. The first is uncoupling of the receptor from proteins which generate the cellular response. The second is internalising receptors so that they cannot be activated. The third is reducing production of receptors so less are available. In general mechanism 1 is short term, 2 is mid-term and 3 is long term.
What happens when you have too much dopamine?
Dopamine is a chemical in the brain which controls happiness. It acts a bit like a reward for your brain. Though it is perfectly healthy in moderation, an excess of dopamine is believed to be related to schizophrenia, or a mental illness that affects the way you think and act.
A thich waxy coating on the leaves of some desert plants most likely permits the plants to what?
The waxy coat helps to reduce water loss from the leaves.
What factors would most likely cause a hurricane to decrease its strength?
Cooling down. This can be from moving to cooler waters, or moving over land, which will also reduce its energy.
Does dopamine agonists contribute to tinnitus?
They certainly can for me. It is an indicator to reduce your dose.
Why does meditation reduce pain?
they block pain receptors
Explain the function of stretch receptors in regulating breathing?
The function of the stretch receptors in regulating breathing is to reduce the respiratory rate.
What therapeutic aspects does cold water have?
Cold water is selected to reduce inflammation.

How drugs affect the nervous system?
Depressant Drugs: Alcohol, Benzodiazepines, Barbiturates and other central nervous system depressant drugs act primarily on a neurotransmitter substance known as GABA (Gamma Aminobutyric Acid). GABA is an inhibitory neurotransmitter that makes other neurons less likely to activate. The depressant drugs are GABA agonists, acting to help GABA reduce neuronal activation more efficiently than it usually would. Alcohol also inhibits (acts as an antagonist against) another excitatory neurotransmitter (Glutamate), making it harder for Glutamate to get the nervous system excited. Stimulant Drugs Amphetamines have their primary effects on the neurotransmitter Dopamine. Amphetamines both induce the terminal button of Dopamine-producing neurons to let more Dopamine out than normal, and also keep that Dopamine out in the synapse longer than it normally would be allowed to stay. Amphetamine also acts agonistically on receptors for a different neurotransmitter, Norepinephrine, by competing with Norepinephrine for post-synaptic receptors and turning those post-synaptic receptors on. Cocaine has its major effect by blocking the re-uptake of the neurotransmitters Dopamine and Serotonin. Opioid Drugs: Opioid drugs bind to special endorphin receptors in the brain (the 'mu', 'kappa', 'sigma' 'delta' and 'gamma' receptors) that have to do with pain. When these receptors are occupied and activated, the perception of pain lessens. Drug treatments for opioid addictions sometimes include the administration of Naltrexone, which is an opioid antagonist. Naltrexone competes with the opioids for their receptor sites, but is not itself capable of activating those receptor sites. An opioid addict on Naltrexone is thus rendered more or less incapable of getting high from their opioid drug of choice; they may take an opioid, but it will be blocked from the opioid receptors by the Naltrexone, and will not have its effect. Cannabinoids: Marijuana has a complex set of effects. It acts on the neurotransmitters Serotonin, Dopamine and Acetylcholine. It also binds to a receptor for a recently discovered neurotransmitter known as Anadamide. Hallucinogens: LSD is known to antagonize Serotonin by blocking its release.
Is Thorazine most likely to provide schizophrenia patients with some relief from their auditory hallucinations and paranoia?
Neuroleptics, or antipsychotics, are the drugs most commonly used to treat schizophrenia. They block the dopamine pathways to reduce the amount of dopamine in the brain, which could be one cause of the schizophrenia. However, it's difficult to get patients to stay on their medication because of the unpleasant side effects.
What prescription medications have dopamine in them?
Dopamine hydrochloride (the drug) is a vasopressor. That is, it causes the blood vessels to constrict and thereby raises blood pressure. It can also increase heart rate. Dopamine itself is a naturally occurring neurohormone that acts as a neurotransmitter in the brain.
What have researchers discovered about marijuana and memory?
The hippocampus has THC receptors that reduce short=term memory
How Can The Effect Of Noise Pollution be reduced?
Reduce the emissions (the source sounds) shield the receptors (reducing immissions)
What have researchers discovered about marijuana use and memory?
Researchers have found that frequent marijuana use can impair memory, particularly short-term memory. This effect is thought to be due to how marijuana affects the hippocampus, a region of the brain important for memory. Chronic use during adolescence may have long-lasting effects on memory and cognitive function.
Are there any medications that can reduce the therapeutic effects of Ativan?
Yes, clonidine has been used to reduce symptoms of withdrawal and physical dependence from chronic benzodiazepine use as with Ativan or Xanax.
