Comparative analysis of olfactory pathway.
| Species | Study | Approximate % of CSF drained through olfactory route | Methodology of CSF Tracing | Duration of Observation |
|---|---|---|---|---|
| Sheep | Boulton et al., 1997 | >50% | Intraventricular injection of Human Serum Albumin | 6 h |
| Silver et al., 2002 | >50% | Intercranial Pressure calculation following CP blockage | 300 s | |
| Rats | Boulton et al., 1999 | 40–50% | Intraventricular injection of Human Serum Albumin | 6 h |
| Rabbits | Bradbury et al., 1981 | 40–50% | Intraventricular injection of radioiodinated albumin | 6 h |
| Dogs | Sokołowski et al., 2018 | 10% | Volumetric analysis of the rostral cranial fossa | N/A |
Synthesized comparison of proportional CSF egress occurring by means of an olfactory drainage route as quantified by Bradbury et al., 1981, Boulton et al., 1997, 1999, Silver et al., 2002 and Sokołowski et al., 2018.
