Scientists have proven that blows to the head cause the strengthening of the skull

Experiments by scientists from the Australian Monash University have shown that blows to the head and light shaking make the bone tissue of mammals thicker and stronger. The results of this work were reported in the journal Scientific Reports.
Bridgette Semple and her colleagues conducted experiments with laboratory rats, specifies the resource naked-science.ru. Some of them, at intervals a day, received from one to three blows from a load suspended over their heads. After two and ten weeks, the rats were euthanized and the bones were examined using X-ray microtomography.
It turned out that in rats that received blows to the head, the bones of the skull in the corresponding place begin to thicken. After two weeks, the changes become significant, and after ten – obvious. Thickening is accompanied by a decrease in the thickness of the spongy substance, which is located under the bones of the skull.
Apparently, scientists suggest, this makes the skull better prepared to receive new blows, further protecting the brain. However, how much thickening of the bones protects the brain is still unclear. Therefore, in the future, the authors of the work plan to conduct new experiments with animals.
