Summary Further studies of the neurohypophysis of the hedgehog have confirmed the presence of two distinct types of neurosecretory fibre in the infundibular process. A third type of fibre, possibly containing catecholamines, is found in the upper infundibular stem. Lesions of the paraventricular nuclei result in vacuolation of type I nerve fibres, which contain crystal-like and aggregate bodies. Type II fibres, containing membranous inclusions, with or without osmiophilic material, apparently do not degenerate. The evidence suggests that type I fibres arise in both the paraventricular and supraoptic nuclei.
