Pontine cholinergic mechanisms modulate the cortical electroencephalographic spindles of halothane anesthesia.

abstract：BACKGROUND:Anesthetic potency is assessed by determination of the anesthetic concentration that prevents gross, purposeful movement in response to noxious stimulation. It is unclear whether anesthetics cause a progressive decrease in the number and force of limb movements evoked by noxious stimulation, or a step decrea...
