Our Brains are Equipped for Better Repair

A new study published on Nature Neuroscience proposed that “immune cells rush through channels to get to injured tissue quickly.”

The study was based on the findings of Dr. Nahrendorf’s team. An expert on recovery after stroke, he noticed that immune cells called neutrophils arrived at the damaged area too quickly.

According to The National Institutes of Health bulletin: “Dr. Nahrendorf’s team detected the channels throughout the skull as well as in the tibia, which led them to search for similar features in the human skull. Detailed imaging of human skull samples obtained from surgery uncovered the presence of the channels. The channels in the human skull were five times larger in diameter compared to those found in mice. In human and mouse skulls, the channels were found in the both in the inner and outer layers of bone.

We always thought that immune cells from our arms and legs travelled via blood to damaged brain tissue, says Dr Francesca Bosetti, Ph.D., program director at the NIH’s National Institute of Neurological Disorders and Stroke.”

Now the study changes that: “With the help of advanced imaging techniques, the researchers watched neutrophils moving through the channels. Blood normally flowed through the channels from the skull’s interior to the bone marrow, but after a stroke, neutrophils were seen moving in the opposite direction to get to damaged tissue.

Our big brain is a Darwinian enigma. Darwinists cannot explain it.

And, now it also seems that other effects are forceful too.
