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.
