Changes of hypoglossal nerve activity during inhibition of chewing and swallowing by lingual nerve stimulation
- 28 Downloads
During the inhibition, discharge in some hypoglossal nerve fiber was inhibited, while enhanced in others.
Facilitation or inhibition was produced in the gross potential of the hypoglossal nerve, depending on the interval between paired stimuli, the one to the cortex and the other to the lingual nerve.
Motoparalysis induced by gallamine triethiodide did not alter the response of the hypoglossal units.
Behavior of hypoglossal units during the inhibition was discussed in relation to the neural mechanisms of chewing and swallowing.
