Is it true that the method of action of general anesthesia is not exactly known? In other words, is there no conclusive theory of how it works?

in short: no. There is no definitive answer to how general anesthesia works. We know most of the reactions at the cell receptor level and begin to catalog what brain nuclei are shut down and which are not, but what is lacking is global understanding of the relations of those distinct actions to consciousness.

@Raoul: Wow, that's fascinating that so little is known about it. Are there any good books, textbooks, or papers that outline the current theories of anesthesia's method of action? thanks –  Geremia Sep 5 at 5:00
