The inner workings of the brain are one of biological science ’s greatest mysteries . There is much that scientists do n’t fully understand about the most complex organ in the human physical structure , from how we store memory to why we sleep and dream .
They ’re easy chipping away at its arcanum , though . researcher from Massachusetts General Hospital and Harvard Medical School have discovered the existence of bantam tunnels connecting the skull and the brain in both humans and mouse , according toScience Alert . The findings , published in the journalNature Neuroscience , reveal how immune cellular phone take a “ shortcut ” by traveling through these tunnels to get to the wit in the event of a stroke , meningitis , harm , or other disorder affecting mind mathematical function . The cell , which help to deoxidize inflammation , were antecedently thought to move through the bloodstream .
Prior to this study , researchers did n’t acknowledge whether these cells , a type of white blood cubicle call neutrophils — which help the body defend itself against infection like meningitis — originated in the skull or in the tibia ( a.k.a . the shin bone ) . Using membrane dyes that were inject into the cells of mice , researchers were able to traverse these electric cell and see where they go .

It was determined that more neutrophils were coming from the skull than the tibia , and upon closer inspection , researchers learned that they were traveling through microscopical TV channel that connect bone vegetable marrow in the skull with the outer lining of the psyche . Next , the researchers took pieces of a human skull to determine if the same concept apply to our anatomy . Lo and behold , the channels were indeed visible — and they ’re five time big than the tunnel set up in mouse skulls .
scientist sayfurther research is postulate , but think the finding could help improve their savvy of how certain disease touch the brain . The next step : investigate the function these tunnels play in responding to needlelike diagonal , high blood pressure , Alzheimer ’s disease , and other ill .
