Changes in the central representation of the extraocular muscles in the rat oculomotor nucleus after section and repair of the third cranial nerve.
The anatomical location of motoneurons controlling the extraocular muscles within the oculomotor nucleus was investigated by injecting retrograde horseradish peroxidase (HRP) into individual eye muscles in control rats and in rats submitted to intracranial section and repair of the oculomotor nerve 6 months previously. Compared to the controls, the operated animals showed marked changes in the somatotopic organization of the oculomotor subnuclei. The possible nature of this re-arrangement is discussed.
