Immune cells in the meninges come from bone marrow in the skull and migrate to the brain through special channels without passing through the blood. These immune cells help to guard the brain and spinal cord against inflammation and infection.
A new study sheds light on how immune cells may rush through channels to quickly get to injured brain tissue. Researchers say bone marrow in the skull is more likely to help supply neutrophils to the brain following a stroke.
A new study examines the link between brain development and the bones of the skull roof during the evolutionary transition from dinosaur to bird.
New forensic technique could help to estimate the age of living children and young adults for whom no records are available.
Fossil finding shed light on the changes in penguin brains that accompanied their transition to water, a new study reports.
Researchers have shown there is not enough variation in skull shapes to make a positive forensic identification.
