STAT Health calls the human ear a \u201cbiometric gold mine.\u201d The startup, which emerged out of stealth this morning, is talking specifically about cerebral blood flow (CBF). That\u2019s pretty much what it sounds like: the blood supply to the brain measured over a specific length of time. A lack of blood flow to the brain creates all sorts of unpleasantness, like dizziness, fainting, headaches and \u201cbrain fog.\u201d<\/p>\n

If that last one in particular rings any bells, it\u2019s likely due to ongoing conversations around the cause and symptoms of long Covid. It\u2019s not a medical condition, but it pops up when discussing a variety of impairments. For some time, medical officials have believed that CBF can prove an important biomarker for understanding a variety of conditions.<\/p>\n
