MedicalXpress | мая 01, 2026

A study led by Rafael Gallareto-Sande, a predoctoral researcher at the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH), provides new insights into a network of tiny blood vessels within the cranial bones that play a key role in brain protection. The research, published in The Anatomical Record, reports for the first time the number and size of these microscopic channels, known as vascular microforamina, which connect the cranial bone with the intracranial space.
