[Trigeminal motor nuclei in the mouse: effects of microstimulation and sources of afferent projections]

Motor responses of low jaw to the microstimulation of the motor nucleus of the trigeminal nerve (MNTN) of albino mice have been recorded. They had the latency ranged of 2.5 to 13.5 ms. After microinjections of horseradish peroxidase into the MNTN, retrogradely labeled neurons were revealed ipsilaterally in both sensory and mesencephalic trigeminal nuclei, in the medullary reticular formation, etc.
