The inhaled anesthetics affect many receptors (e.g., GABA A, glycine, acetylcholine, serotonin, NMDA) in manners that plausibly could explain anesthesia. Which receptors mediate anesthesia remains ...

Scientists aren’t exactly sure how this happens, but they know general anesthetics bind with GABA receptors in the neurons to block pain signals. Anesthesiologists often administer general ...

General anesthetics work by altering the activity of specific neurons ... while a second class that includes ketamine primarily blocks excitatory NMDA receptors. The GABA A receptor is a channel that ...
