  • Title: [Motor responses of the facial muscles to local stimulation of the motor cortex and facial nerve nucleus in the white mouse].
    Author: Pronichev IV.
    Journal: Zh Vyssh Nerv Deiat Im I P Pavlova; 1988; 38(1):135-9. PubMed ID: 3376557.
    Abstract:
    The character of motor responses of the facial muscles evoked by stimulation of various regions of the frontal neocortex and of the nucleus of the facial nerve was studied in outbred mice. Motor responses of the vibrissae, of the upper lip and the jaw to monopolar microstimulation in the frontal cortical areas in 55 per cent of the cases had the latencies from 5 to 15 ms. The latencies of the responses to the facial nucleus stimulation ranged from 3 to 12 ms with maximal expressed interval of 4-6 ms. Excitation conduction velocities of the facial nerve estimated on the basis of latencies measurements, were from 1.5 to 12 m/s.
