Most anesthetics produce unconsciousness by enhancing the effect of the neurotransmitter GABA (Gamma-Aminobutyric Acid), which is an inhibitory neurotransmitter in the central nervous system. GABA works by opening chloride ion channels, allowing Cl⁻ ions to enter neurons. This influx of chloride ions hyperpolarizes the neuron, making it less likely to fire, thereby producing sedation and unconsciousness.
