Confirmed: “Secret” Tunnels Connect Our Skulls and Brains
The newly confirmed skull tunnels produce immune system cells and funnel them to the brain in case of inflammation or damageNeuroscientists usesd to think that immune system cells were carried in the bloodstream from, say, big leg bones in order to address brain inflammation following a stroke, injury, or disorder. It turns out that the brain gets neutrophils from much closer to home, right under the scalp. That’s what one group discovered when looking for the cells in the tibia (the larger of the shinbones in the leg) in mice: They found that the skull contributed significantly more neutrophils to the brain in the event of stroke and meningitis than the tibia. But that raised a new question – how were the neutrophils being delivered? “We started examining the skull very carefully, looking at it from all angles, trying to Read More ›
