Localization of masticatory motoneurons in the trigeminal motor nucleus of the guinea pig.

The myotopical arrangement of masticatory motoneurons was examined in the guinea pig by the horseradish peroxidase method. The trigeminal motor nucleus was composed of dorsolateral and ventromedial divisions; the former was seen in the whole rostrocaudal extent of the nucleus, while the latter was present at levels of the caudal two thirds of the nucleus. The jaw-closer motoneurons were located in the dorsolateral division, and the jaw-opener motoneurons (mylohyoid and anterior digastric motoneurons) were seen in the ventromedial division.

Lingually induced inhibitory postsynaptic potentials in hypoglossal motoneurons after axotomy.

Inhibitory postsynaptic potentials (IPSPs) produced in axotomized hypoglossal motoneurons by stimulation of the lingual nerve were explored in cats. In the ipsilateral lingual afferent synapses, the effectiveness of inhibitory synapses for the long-lasting IPSP was diminished in axotomized hypoglossal motoneurons earlier after transection of the hypoglossal nerves, than the effectiveness of inhibitory synapses for the short-lasting IPSP.
