Abstract |
Trochlear motorneurons were identified by applying horseradish peroxidase(HRP) to superior oblique muscle in cats. Ninety five to ninety seven percent of the contralateral trochlear nucleus were stained 3-5% of ipsilateral side also labelled by HRP. These findings showed that superior oblique muscle was innervated by trochlear nuclei on both side. |
