The device that massages the face and neck enhances the system to get rid of brain waste, indicating that it may reduce the severity of cases such as Alzheimer’s disease.
The coffee liquid (CSF) takes into account our brain, and it is pumped in it before leaving through A network of thin tubes It is called glossy vessels. Studies in mice have shown that this liquid The waste products made by the brain cells come outIncluding Beta-amyloid, a protein associated with conditions such as Alzheimer’s and Parkinson’s disease.
These scientists have pushed to question whether to enhance the CSF flow can enhance the health of the brain. But the glycal vessels have been identified in depth in the neck only, which makes it difficult to manipulate, he says Joe Yong Koh At the Advanced Korea Institute of Science and Technology in South Korea.
Now, KoH and his colleagues found a network of ice vessels about 5 millimeters under the skin on the face and neck of mice and monkeys. They discovered this discovery by injecting animals using the fluorescent dye called CSF and photographing it under anesthesia. “We have used a different type of anesthesia used in previous studies – anesthesia has prevented other studies to detect vessels near the skin,” says Koh.
To find out if the massage of these vessels can enhance the CSF flow, the researchers built a device with a small rod connected to a large -scale cotton ball 1 ° C. They used it for a stroke down along the face and neck of the ancient mice, between the ages of two years, and the younger mice that were a few months old, for a minute. “The massage is gently on the face and the upper neck can push the liquid down, which enhances the CSF flow,” says Koh.
After up to half an hour, the CSF flows about three times faster through mice brains, on average, compared before animal massage. The procedure appears to reflect age -related decreases in the CSF flow. “After motivation, the old mice flow was similar to the flow of younger mice [that hadn’t yet been massaged]Koh says.
In unpublished work, the team found similar results in monkeys. Moreover, the ice vessels under the skin of the human corpses have been identified, indicating that the massage can also enhance CSF in people, says Koh.
But mice and monkeys have some anatomical differences for humans, so more work is needed to create this, he says Vica Kevinimi At Olu University in Finland. “It’s a fairly different ball game.”
More than that, it is still unclear whether to enhance the CSF flow can slow down in the aging of the brain or protection from neurological degenerative diseases such as Alzheimer’s disease, he says Stephen Broles At the University of Bern, Switzerland. Koh says his team is planning to explore this in jam mice to get features of Alzheimer’s disease.
