Study Documents Quantity and Dimensions of Vascular Microforamina in Skull, Linking Bone to Brain Defense

A recent study has shed light on a network of microscopic blood vessels within the skull that appear to be crucial for brain defense. Researchers have successfully documented the quantity and dimensions of these tiny channels, called vascular microforamina, which create a connection between the cranial bone and the space within the skull.

The research, which was published in The Anatomical Record, was spearheaded by Rafael Gallareto-Sande, a predoctoral researcher at the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH). The study marks the first time that scientists have reported the specific number and size of these vascular microforamina. These microchannels are significant because they physically link the cranial bone to the intracranial space, suggesting a direct pathway that could be vital for immune responses and brain protection.
