Receptor (Definition)

An organ, cell or molecule that accepts an outside signal and causes an internal change. Eyes receive light, touch receptors send messages to the brain when stimulated by pressure and estrogen receptors bind Estradiol causing responses of normal breast, ovary and uterus cells to rising and falling levels of the female steroid hormones. Most of the time "receptor" refers to one ...Read more

Can you tell me in myasthenia gravis why do you give an acetylcholine esterase inhibitor instead of a direct receptor agonist?

Can you tell me in myasthenia gravis why do you give an acetylcholine esterase inhibitor instead of a direct receptor agonist?

Because...: If you provide an agonist your muscles will contract continually. The acetylcholine esterase inhibitor prolongs the life of acetylcholine released naturally from your motor nerves so you only have muscle contraction when your brain orders it. ...Read more

If a certain meditation releases a lot of dopamine/serotonin, etc; is there a probability that overdoing it could down-regulate receptors in my brain?

If a certain meditation releases a lot of dopamine/serotonin, etc; is there a probability that overdoing it could down-regulate receptors in my brain?

Serontinergic: Receptors do down regulate when a medication is used, they up regulate when there is no seratonin. Down regulation of Dopamine receptors does occur in cases of abuse with cocaine, high dose amphetamine , etc, not with common medications for mood. Also people may have different levels of receptors without meds, thrill seekers needing more Dopamine release to feel a charge, . ...Read more

What serotonin receptor is most important for depression?

What serotonin receptor is most important for depression?

Way too simplistic: Your brain isn't a 4-cylinder Chevy, where 1 circuit controls 1 function. There are dozens of serotonin receptor subtypes organized into 3 subfamilies. The modulation of mood involves a complex and subtle interplay of excitation & inhibition at multiple receptor subtypes. A neurochemist can spend an entire career researching just 1 receptor subtype. ...Read more
