RESEARCH:

Grants Received:

1. $15,000    7/88-6/89   "Study on the Regeneration of Long Axons in the Spinal Cord of Adult Rat"  Copeland Fund.

Research Conducted:

1. Development of a model to study the pathophysiology of hemifacial spasm.

In adult rats chronic stimulation of the facial nerve trunk was carried out with implanted electrodes.  After 2-6 weeks of stimulation, electrophysiological testing of these animals revealed signs of hemifacial spasm similar to those in human patients. The facial nucleus  was also studied with stereotactically placed electrodes.  These studies were carried out in conjunction with Professor A. Moller.

2. Study of evoked potentials generated by direct paraspinal stimulation of the spinal cord and its application in the monitoring of the integrity of the spinal cord in the cat with Professor Marvin Bennett.

3. Study in rats to evaluate the ability of long axons to regenerate after a high cervical lesion with Professor R. Lund.

Unilateral dorsal column lesion was created between C1 and C2 in adult rats.  A sciatic nerve graft was then inserted in the lesion.  After a variable survival period, SSEP was recorded from the scalp and dorsal column nuclei.  Transganglionic labelling of the median ulnar and sciatic nerves on the side of the lesion was carried out.  Histological evaluation did not reveal any long tract axons from the three nerves to have regenerated into the graft.

4. Anatomical study in the human cadaver specimens to evaluate the intradural exposure of the clivus by the subtemporal preauricular infratemporal approach.

5. Anatomical studies in human cadaver to elucidate microsurgical configuration of the cavernous sinus, jugular and hypoglossal foramina.

6. Immunohistochemical and Western Blot techniques to elucidate the expression of Adhesion Molecules in Chordomas.

7. Tissue culture of Chordoma cell lines.
