A surface and neck massage device enlarges the brain’s waste disposal system, which suggests reduce the severity of conditions Alzheimer’s pain.
Cerebrospinal fluid (CSF) has shed our brain, pumped it before leaving a Network in thin tube called glymphatic vessels. Studies of rats show that this liquid Getting the debris made with brain cellsincluding beta-amyloid, a protein involved in conditions such as Alzheimer and Parkinson disease.
This makes scientists think if the development of CSF flow can boost the brain. But glymphatic vessels were previously identified in the deep neck, which makes it difficult to manipulate, as Gou Boh Koh In the Korea Advanced Institute of science and technology in South Korea.
Now, Koh found and his associated networks of Glymphatic Vessels about 5 millimeters under the skin and neck of mice and monkeys. They make the discovery by injecting animals with a fluorescent Tina labeled CSF and imaging under anesthesia. “We use a different type of anesthesia than used before studies – other studies of studies used to prevent vessels closer to the skin,” says Koh.
To see if massage in these ships can extend CSF flow, researchers build a device with a small rod attached to a 1-centimeter-wide cotton ball. They used it to withdraw the face and neck of older mice, aged 2 years, and younger mice a few months old, for a minute. “Gently hit the face and the upper neck can push fluid, promoting the csf flow,” says Koh.
Up to half an hour ago, the CSF strikes three times faster than rats in rats, generally, compare before animals. The procedure is as well as repositioning the declarations related to the CSF flow. “After arousing, the csf’s flow of old mice is similar to the younger mice (which is not yet submissive),” says Koh.
In unexplored job, the team finds the same results with monkeys. What else, did they hold the glymphatic vessels under the skin of human cadavers, suggesting the csf’s flow, says it is like Koh.
But mice and monkeys have some differences in anatomical people who work more necessary to build it, as Vesa Kiviniemi At the University of Ouru in Finland. “It’s a different ball game.”
What else, isn’t it clear enough if the development of the csf flow of the brain or protect against neurodegenerative diseases such as alzheimer disease, as Steven Proulx At the University of Bern in Switzerland. Koh says his team plans to check it in rats with parts of Alzheimer’s disease.
