N normal phenotype
nervous system
• depression of spontaneous action potential firing due to etomidate or enflurane is less than controls (J:81497)
• duration of early local field potentials is reduced less than in controls after administration of etomate (J:105539)
• 0.2 microM etomate causes only half the neural depression in brain slices from the somatosensory cortex as seen in controls (31% vs 65%)
• etomidate has less affect on GABA induced chloride currents in hippocampal pyramidal cells

behavior/neurological
N
• motor activity and response to noxious thermal stimuli are normal
• behavioral responses to anesthetics are reduced relative to controls
• hind limb withrdrawl reflex is not lost at any dose of etomidate
• responses to volatile anesthetics such as enflurane and halothane are normal
• duration of the loss of righting reflex after administration of etomidate or propofol is less than for controls
• responses to volatile anesthetics such as enflurane and halothane are normal
• involuntary muscular contractions and spasms are seen after administration of very low doses of etomidate
