Impact of tongue exercise on hypoglossal axis survival, structure, and output in a rodent model of hypoglossal motor neuron degeneration

Abstract: Intralingual injections of CTB-SAP result in decreased XII motor neuron survival and degenerative changes in the XII nerve consistent with what is seen in many MNDs. Although these deficits are not mitigated by tongue exercise, we do observe increased microglial fractional area/density in the XII nucleus of CTB-SAP + exercise rats. In addition, deficits in XII motor output are mitigated by tongue exercise, indicating neuroplasticity despite significant loss of XII motor neurons and XII nerve degeneration.
