In order to demonstrate regulation of retrograde transport by synaptic inputs, we examined effects of transection of the lingual nerve on retrograde transport of HRP in the rat masseter and hypoglossal motoneurons. Rats were performed transection of the unilateral lingual nerve and then HRP was injected bilaterally into the masseter and tongue muscles. Sixteen hours later brainstems were removed and serial frozen 60 μm sections of brainstems were processed for HRP activity. The amount of transported HRP in the masseter and hypoglossal motoneurons was measured by using an image processing system. The number of HRP-positive cells was also counted. The values were compared between the control and transected sides. The transection of unilateral lingual nerve decreased significantly the retrograde transport of HRP in the ipsilateral hypoglossal motoneurons although certain change in the masseter motoneurons was not detected.
