Abstract　： [Abstract] To elucidate the detailed mechanism of the Reilly syndrome due to trigeminal irritation, the interaction between trigeminal nerve stimulation and the function of the neurons in the lateral horn of the spinal cord was investigated using electrophysiological techniques. Some of the neurons in the lateral hom showed evoked unit discharge by a single stimulation of branches of the trigeminal nerve. The rate of spontaneous discharge of neurons in the lateral horn changed after repetitive trigeminal nerve stimulation. There were three types of change in discharge rate : increased, decreased and indifferent. These three types of neurons were randomly scattered throughout the lateral horn area with no regularity and the increased type was the type most frequently detected. Summation effects on the discharge rate of the lateral horn neuron were observed among the branches of the trigeminal nerve. These findings suggest that some of the neurons in the lateral horn receive direct trigeminal nerve inputs polysynaptically and strong and long-lasting irritation to the trigeminal nerve consequently modifies the firing pattern of the lateral horn neurons.
