Abstract

Cerebrospinal fluid (CSF) drainage pathways from the rat brain were investigated by the injection of 50 μl Indian ink into the cisterna magna. The distribution of the ink, as it escaped from the cranial CSF space, was documented in 2 mm thick slices of brain and skull cleared in cedar wood oil and in decalcified paraffin sections. Following injection of the ink, deep cervical lymph nodes were selectively blackened within 30 min and lumbar para‐aortic nodes within 6 h. Within the cranial cavity, carbon particles accumulated in the basal cisterns but were also distributed in the paravascular spaces around the middle cerebral arteries and the nasal‐olfactory artery. Carbon particles in the subarachnoid space beneath the olfactory bulbs drained directly into discrete channels which passed through the cribriform plate and into lymphatics in the nasal submucosa. Although ink was distributed along the subarachnoid space of the optic nerves and entered the cochlea, the nasal route was the only direct connection between cranial CSF and lymphatics. Arachnoid villi associated with superior and inferior sagittal sinuses were identified and a minor amount of drainage of ink into dural lymphatics was also observed. This study demonstrates the direct drainage of cerebrospinal fluid through the cribriform plate in anatomically defined channels which connect with the nasal lymphatics. Such a pathway is compatible with the observed rapidity of the bulk flow drainage of CSF in the rat, accords with the known specificity of immunological reactions to antigens injected into brain tissue, and may also serve as a route for drainage for lymphocytes and macrophages from the brain to the regional cervical lymph nodes.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Antigens move from the CSF compartment to mandibular and deep cervical lymph nodes by exiting through perineural pathways-including the olfactory, optic, and trigeminal nerves-into an extensive network of lymphatic vessels that reside outside the CNS.

    “Antigens are known to move from the CSF compartment to mandibular and deep cervical lymph nodes by exiting through perineural pathways—including the olfactory, optic, and trigeminal nerves (9, 63)—into an extensive network of lymphatic vessels that reside outside the CNS.”

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.
