come close to explaining how consciousness is lost on a dog. the researchers are using mouse frames to try to better understand how different substances used in anesthesia work. for many decades scientists thought all anesthetics essentially blocked information from reaching neurons by causing a malfunction and their lip it membranes. however this lip at theory has since been abandoned today researchers know that every anesthetic has a different way of causing a consciousness of. brain tissue cultures taken from areas of the brain involved in loss of consciousness are put into a nutrient solution for several weeks during which time they grow into many brains which can be used for experiments. this is what researchers have discovered so far. in our central nervous systems receive and process stimuli from
