“…This experimental study confirmed DE CASTRO's previous view, based on light microscopy, that the nerve fibers terminating on chief cells are sensory (DE CASTRO, 1928). BISCOE et al (1970), on the other hand, reported that after the operation, there was an absolute progressive reduction in the number of vesicle-containing nerve endings on the chief cells as compared with control non-operated side. They concluded that nerve fibers terminating on the chief cells are all motor; sensory endings participating in chemoreception might be situated in the interstitial space, not in contact with the chief cells.…”

“…The concept that chemoreceptors of the carotid bodies receive an efferent nerve supply, via the IXth nerve rootlets, which modulates their activity is derived from electrophysiological and degeneration studies in the cat [Biscoe, Lall and Sampson, 1970;Biscoe and Sampson, 1968;Neil and O'Regan, 1971b]. Changes in chemoreceptor activity, postulated to be the results of activity in such fibres, have been demonstrated [Neil and O'Regan, 1971a].…”

An attempt has been made to determine where in the lower brainstem the. cell bodies of nonsympathetic efferent fibres in the aortic nerve of the cat and rabbit are located. Horseradish peroxidase (HRP) O'Regan, 1971a] but no attempts to define the location of their cell bodies have been reported.During the course of experiments on the brainstem projection of C fibres in the aortic nerve of the cat, recordings were made from neural elements excited antidromically by stimulation of the aortic nerve, but evidence that the elements were somata rather than axons could not be obtained [Donoghue, Kidd and McWilliam, 1978]. It was decided to use the retrograde transport of horseradish peroxidase (HRP) with the objective of defining the brainstem location of the 145

“…Later, HESS and ZAPATA (1972) revised De Castro's experiment and confirmed his observation. On the other hand, BISCOE et al (1970) repeated De Castro's experiment using an electron microscope and observed degeneration of the nerve endings on the glomus type I cells after an intracranial section of the glossopharyngeal nerve. The conflicting nature of the results has been ascribed to a technical difference in the sectioning of the nerve roots.…”

Using the horseradish peroxidase (HRP) technique, the central origin of efferent fibers in the carotid sinus nerve (CSN) was examined in the cat. To avoid false labeling due to uptake from the nerve endings in the adjacent tissues of the CSN, the critical amount of HRP was sought, which was estimated at 0.5 mg. Applying 0.5 mg of HRP to the central cut end of the CSN, many labeled cells were found in the petrosal ganglion, but no labeled cells were found in the central structure. The findings of this study indicate that the origin of the most efferent fibers in the CSN is not in the central structure, but that it may be in the extracranial part of the glossopharyngeal nerve.
