The origin of the vasopressinergic and oxytocinergic innervation of the rat brain with special reference to the lateral septum

Abstract

The origin of the vasopressin-containing fibers in the rat lateral septum was studied by means of lesioning specific areas, in which vasopressin-containing cells are found, or by surgically separating the septum from the underlying structures. Following these procedures sections of the brain were stained immunocytochemically for the presence of vasopressin. In addition, retrograde labeling tracers were injected in the lateral septum. Lesioning of the paraventricular nucleus did not result in the disappearance of vasopressin fibers from the lateral septum, nor from the various other areas studied. It did, however, cause the disappearance of fibers from the nucleus of the solitary tract and the nucleus ambiguus. By contrast, after the same lesion practically the whole oxytocinergic innervation of the brain disappeared. Injection of tracers into the lateral septum revealed retrograde labeled cells, e.g. in the bed nucleus of the stria terminalis, but not in the paraventricular and supraoptic nucleus. Horizontal cuts under the lateral septum, intersecting the diagonal band of Broca, resulted in a dramatic decrease of the vasopressin fibers in the lateral septum, suggesting that the fibers enter the septum via this structure. Moreover, since the vasopressin fiber density was found to decrease drastically in the lateral septum after lesioning the bed nucleus of the stria terminalis, the vasopressin cells found in this area are probably the source of these fibers. Other areas where fibers were seen to decrease after lesions of the bed nucleus are the diagonal band of Broca, the area of the anterior amygdala, the lateral habenular nucleus, the periventricular gray, and the locus coeruleus.

TL;DR

Using lesions and retrograde tracing in rats, this study shows that the vasopressin (VP) fibers innervating the lateral septum arise from the bed nucleus of the stria terminalis (BNST), not from the paraventricular (PVN), supraoptic (SON) or suprachiasmatic nuclei. In contrast, the brain's oxytocinergic innervation appears to derive predominantly from the PVN.

Key findings

  • Unilateral horizontal knife cuts separating the septum from underlying structures drastically reduced VP fiber density in the lateral septum only when the cut extended far enough rostrally to intersect the diagonal band of Broca; more caudal cuts produced only slight reduction. Intersected fibers appeared swollen, suggesting accumulation proximal to transection.
  • Unilateral BNST lesions (diameter ~2.5 mm) clearly reduced VP fiber density ipsilaterally in the diagonal band of Broca, lateral septum, lateral habenular nucleus, area of the anterior amygdala, periventricular gray and locus coeruleus; no diminution was noted in other areas studied (Table I).
  • Small PVN lesions (~1.5 mm) decreased VP fibers only in the nucleus of the solitary tract and nucleus ambiguus. Large PVN lesions (~2.5 mm) additionally eliminated VP staining in the periventricular and dorsomedial hypothalamic nuclei, and caused almost complete disappearance of the brain's oxytocinergic innervation — but did not remove VP fibers from the lateral septum.
  • Retrograde tracer injections into the VP-dense part of the lateral septum labeled cells in the BNST (and lateral hypothalamic area, just lateral to PVN, and dorsal to SON) but not in the SCN, PVN or SON.

Methods

  • Retrograde labeling: 37 male Wistar rats (250–300 g) received injections into the lateral septum of HRP (stereotactic or iontophoretic), WGA-HRP, True Blue or Granular Blue; sections processed with diaminobenzidine or tetramethylbenzidine methods or viewed by fluorescence microscopy.
  • Lesion studies: male Wistar rats (160–190 g) received radiofrequency lesions of the PVN (5 small at 50 °C, 5 large at 60 °C) or unilateral BNST lesions (6 rats at 65 °C), or Halász-knife horizontal cuts separating the septum unilaterally from underlying structures (6 rats). After 2.5–3 weeks, 100 μm vibratome sections were stained immunocytochemically for VP or oxytocin and fiber density compared with untreated controls.
  • Hippocampal and ventral tegmental labeling served as positive controls for retrograde tracing efficacy.

Limitations

  • The authors state they cannot exclude that VP fibers in the lateral septum originate outside the BNST and merely pass through it; they note this requires combining immunocytochemistry with retrograde tracing.
  • The origin of VP fibers in the dorsal raphe nucleus, medial amygdala, hippocampus and ventral tegmental area remained obscure, as no lesion reduced fibers in these areas.
  • Bilateral BNST lesions were not performed because bilaterally lesioned rats failed to survive surgery; residual fibers after unilateral lesions could reflect contralateral crossover or additional sources (stated by the authors).

    The citation to De Vries and Buijs is attached to the BNST input, not the MeA input. Their summary (p. 2) reports that BNST lesions sharply reduced vasopressin fibers in the lateral septum, but calls BNST cells only the probable source. The Discussion (p. 9) says fibers originating elsewhere might instead pass through the BNST, so it does not establish the direct BNST input as stated. (LLM, conf=0.84)

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.
