ウサギの温度眼振の新しい誘発法

抄録

A simple method of inducing caloric nystagmus in the rabbit was devised. The animal with black eyes is positioned on its back with the neck ventriflexed 90 degrees in order to bring the horizontal semicircular canal into the vertical plane. Eight cc of cubical ice at 0°C is then placed on the skin posterior to the external auditory meatus, so as to allow the ice to cool the ipsilateral temporal bone for approximately four minutes. Nystagmus directed to the opposite side was consistently eveloped about 2 minutes after the start of the stimulation, and easily recorded by electronystagmography without any special instrument for fixation.
