Effect of Acupuncture on Excitability of Auditory Cortex of Guinea Pig

To investigate the mechanism of acupuncture in treatment of deafness, the animal experiments were designated to elucidate its effect on the excitability of the auditory cortex. In experiments with the electro physillogical methods on guinea pig, an increase in the amplitude of the evoked potential of the auditory cortex followed by a series of repetitive after discharges in response to a click during needling the acupuncture points employed in the clinics demonstrated that the excitablity of the auditory cortex was enhanced under the action of acupuncture. This finding showed evidence that the increse in the excitability of the auditory cortex might be considered to play a role for explaining the mechanism of acupuncture effect. It was benefit to promote the analytic and synthetic function of the auditory cortex in processing the sound signal and made the residual hearing to beutilized sufficiently.
