主　　题：vestibular nuclei caloric stimulation electrophysiology 

摘      要：Summary:In order to know the effects of caloric stimulation on neuronal firing in medial vestibularnuclei(MVN)by middle ear irrigation,the middle ear was irrigated with ice(4℃),hot(44℃),and warm(37℃)water,and the firing rate of MVN neuron was extracellularly *** re-sults showed that the firing rate of MVN neuron was changed by caloric stimulation,and the majori-ty of MVN neurons showed excitation by irrigation with hot water and inhibition by ice water(typeA).The neuronal firing was recovered immediately after the cessation of the stimulation.I It wasconcluded that the neuronal firing rate in MVN was changed by caloric syimulation in middle ear *** response was different in various neurons.
