In a new study, a light-sensitive moiety has been added to propofol, a commonly used anesthetic, allowing its narcotic effect to be controlled by light. The compound also offers a possible route to the treatment of certain eye diseases. Inhibitory neurotransmitters dampen the activity of neurons.This regulatory effect forms the basis for the action of many anesthetics.For example, propofol, a common anesthetic,interacts with receptors on neural cell membranes that normally bind the inhibitory neurotransmitter gamma-amino butyric acid (GABA).To see more details visit,To see more details visit,www.medicalnewstoday.com
