Gross dissection, light and scanning electron microscopy, and \u03bcCT analysis revealed the presence of a foramen of Luschka in the American alligator (<jats:italic>Alligator mississippiensis<\/jats:italic>). In this species, the foramen of Luschka is a notch in the dorsolateral wall of the pons immediately caudal to the peduncular base of the cerebellum, near the rostral end of the telovelar membrane over the fourth ventricle. At the foramen of Luschka there was a transition from a superficial pia mater lining to a deep ependymal lining. There was continuity between the lumen of the fourth ventricle and the subdural space, via the foramen of Luschka. This anatomical continuity was further demonstrated by injecting Evans blue into the lateral ventricle which led to extravasation through the foramen of Luschka and pooling of the dye on the lateral surface of the brain. Simultaneous subdural and intraventricular recordings of cerebrospinal fluid (CSF) pressures revealed a stable agreement between the two pressures at rest. Perturbation of the system allowed for static and dynamic differences to develop, which could indicate varying flow patterns of CSF through the foramen of Luschka.<\/jats:p>","DOI":"10.1111\/joa.13972","type":"journal-article","created":{"date-parts":[[2023,11,15]],"date-time":"2023-11-15T21:17:41Z","timestamp":1700083061000},"page":"391-401","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The
