A case of intramedullary thoracic schwannoma in a 40-year-old woman without signs of von Recklinghausen's disease is reported and the hypotheses as to its origin are discussed. The literature covering 11 other cases is reviewed.
The distribution of γ-aminobutyric acid (GABA) in the human cerebellar cortex was studied using immunohistochemistry for glutamic acid decarboxylase (GAD), the enzyme that catalyses GABA synthesis. Observations by light microscopy revealed, in all layers of the cerebellar cortex, strong, punctate positivity for GAD, related to putative GABAergic nerve… (More)
The distribution of cholinergic nerve fibres associated with the microvasculature of the human parietal cerebral cortex was investigated by immunocytochemistry, employing monoclonal antibodies against choline acetyl-transferase, the acetylcholine-synthesizing enzyme. The results revealed strongly immunoreactive nerve fibres in the tunica adventitia of… (More)
