Microplastics block blood flow in the brain, mouse study reveals


Real-time imaging shows how plastic-stuffed cells form clumps that affect mouse movement.

One study last year, for example, found that people with micro- and nano-plastics in fatty deposits in their main artery were more likely to experience a heart attack, stroke or death 2. In the latest study, published in Science Advances today, Haipeng Huang, a biomedical researcher at Peking University in Beijing, and his colleagues wanted to better understand how microplastics affect the brain. They used a fluorescence imaging technique called miniature two-photon microscopy to observe what was happening in mouse brains through a transparent window surgically implanted into the animal’s skull.
