Axonal projections of pulmonary slowly adapting receptor relay neurons in the rat.
Abstract
We elucidated efferent projections of second‐order relay neurons (P‐cells) activated by afferents originating from slowly adapting pulmonary receptors (SARs) to determine the central pathway of the SAR‐evoked reflexes. Special attention was paid to visualizing the P‐cell projections within the nucleus tractus solitarii (NTS), which may correspond to the inhibitory pathway from P‐cells to second‐order relay neurons (RAR‐cells) of rapidly adapting pulmonary receptors. P‐cells were recorded from the NTS in Nembutal‐anesthetized, paralyzed, and artificially ventilated rats. First, we used electrophysiological methods of antidromic mapping and showed that the majority of the P‐cells examined projected their axons to the caudal NTS and to the dorsolateral pons corresponding to the parabrachial complex. Second, a mixture of HRP and Neurobiotin was injected intracellularly or juxtramembranously into P‐cells. (1) Stained P‐cells (n = 7) were located laterally to the solitary tract and had dendrites extending characteristically along the lateral border of the solitary tract. (2) All P‐cells had stem axons projecting to the ipsilateral medulla. Of these, the axons from five P‐cells projected to the nucleus ambiguus and its vicinity with distributing boutons. Some of these axons further ascended in the ventrolateral medulla, and distributed boutons in the areas ventral or ventrolateral to the nucleus ambiguus. (3) All the P‐cells had axonal branches with boutons in the NTS area. In particular, axons from three P‐cells projected bilaterally to the medial NTS caudal to the obex, i.e., to the area of RAR‐cells. These results show anatomic substrates for the connections implicated in the P‐cell inhibition of RAR‐cells as well as the SAR‐induced respiratory reflexes. J. Comp.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
