Research Abstract

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.
