Suppressing local perception helps with stroke recovery

U.S. scientists have found that cutting off the beard to suppress part of the perception of laboratory mice can promote faster recombination of brains damaged by stroke, faster and better recovery, and hopefully help develop new treatments or drugs for post-stroke recovery.
study was conducted by researchers at Washington University (St. Louis). Ischemic stroke can cause damage to the cerebral cortical layer, impairing motor skills and thinking. Neurons around the damaged site spontaneously perform "functional recombination" to take over the duties of necrotic neurons and achieve functional rehabilitation. The researchers speculate that human recombination of neurons may enhance recovery.
Researchers report in a new issue of the American journal
that they caused stroke in the area of the lab rat's brain responsible for the sensation of the right front paw, then cut off some of the lab mice's beards and kept them short for eight weeks. After about 5 weeks, the mice with their beards cut off fully recovered and were able to use their right front paws normally. The control group without a beard recovered slowly and the right front paw function never fully recovered.
for rodents, beards are important sensory organs that provide a wealth of information about their surroundings, and cutting off the beard inhibits this perception. Brain scans showed that after cutting off the beard, the beard cortical cortical layer of the lab mice's brains recombined quickly, processing sensory signals from both the beard and the front paws. The researchers say there are similar recombinations in the human brain, such as the recombination of the cortical layer of blind people who process visual signals for other functions, making them more sensitive to sound, language and even mathematically better.
also found that neuron recombination was regulated by a substance called the cytostebra active regulator protein, which could not be recovered in laboratory mice without the protein. Previous studies have shown that the protein alters connections between neurons and is essential for processing information and forming memories. (Source: Xinhua News Agency)
