Relations between intensities of electrical noxious stimulus applied to the tooth pulp and magnitudes of evoked responses at various relay stations of tooth pulp afferents were investigated with lightly anesthetized rats. The stimulus-response function in each relay station and the cerebral cortex follows the power function only in the range of lower, but noxious, stimulus intensities; however, it deviates from it in the range of higher ones, the exponent of the function becoming smaller. The higher the relay station locates, the smaller the exponent value is.
在轻度麻醉的大鼠身上，研究了施加于牙髓的电伤害性刺激强度与牙髓传入神经不同中继站诱发反应大小之间的关系。每个中继站和大脑皮层中的刺激-反应函数仅在较低但有害的刺激强度范围内遵循幂函数；然而，在较高刺激强度范围内则偏离该函数，函数的指数变小。中继站位置越高，指数值越小。
