General anesthesia phenomena

This simple quatrain wonderfully epitomizes the essence of the human mind. Awareness of one s inner and outer environments is central to the functioning of the human mind. Consciousness is the enigmatic phenomenon that is crucial to the interface between brain and mind. General anesthetics are drugs that temporarily rob us of our consciousness GABA is a key molecular target for general anesthesia. 

The functioning of the brain is dependent on its composition and structure that is, on the molecular environment of the mind. The presence in the brain of molecules of lV,N-diethyl-D-lysergamide, mescaline, or some other schizophrenogenic substance is associated with profound psychic effects (3). Gherkin has recently pointed out (4) that in 1799 Humphry Davy described similar subjective reactions to the inhalation of nitrous oxide. The phenomenon of general anesthesia also illustrates the dependence of the mind (consciousness, ephemeral memory) on its molecular environment (5).
