Effect of Hemicerebellectomy upon the Cytochemistry of Neurons in the Lateral Vestibular Nucleus

Abstract

RNA content and succinoxidase activity was measured in single Deiters' giant nerve cells from the lateral vestibular nucleus in rabbits subjected to hemicerebellectomy. Postoperatively there was a decreased RNA content bilaterally after 1–2 weeks and almost restored values after 6 weeks. The succinoxidase activity showed asymmetrical changes with initially higher values on the operated side and with a rise on the contralateral side after 1 week. The succinoxidase activity and RNA content later returned to approximately preoperative values.
