The mechanism of neural processing in the pontine nuclei that link the cerebrum to the cerebellum

研究了苔藓纤维投射神经元在脑桥核和三叉神经核的动作电位发射频率。在切片制备中，脑桥细胞和三叉神经细胞均未出现超过500hz的高频放电。这一发现与在麻醉动物体内观察到的苔藓纤维的高频放电形成鲜明对比。因此，在体内制备中，可能存在一种增强细胞兴奋性的机制。

The frequency of action potential firing of mossy-fiber projecting neurons in the pontine nuclei and the trigeminal nuclei were investigated. In the slice preparation, neither the pontine cells nor trigeminal cells showed high-frequency firings exceeding 500 Hz. This finding was in striking contrast to the high-frequency firing of mossy fibers that had been observed in anaesthetized animals in vivo. Therefore, it is suggested that, in the in vivo preparation, a mechanism that enhances cellular excitability might have a significant effect.
