The Brain Has Sensors That Detect Blood Flow, Preventing Neurodegenerative Diseases.
However, This Mechanism Could Malfunction Under Certain Conditions, Increasing The Blood Flow, Causing High Blood Pressure, Headaches, Migraines, And Strokes
A recent study has discovered that the brain has sensors to monitor its blood supply. It is the organ that required most blood and oxygen, and its sensors can signal the heart to pump more blood or to decrease the heartbeat. A low level of blood and oxygen results in mental conditions such as Alzheimer’s disease, dementia, and cognitive decline. On the other hand, an excessive heartbeat is one of the physiological causes of high blood pressure. These sensors are called astrocytes, which, when detecting lower blood supply to the brain, release a chemical to nearby nerves, instructing the blood vessels to increase blood flow to the brain. Researchers believe that there are conditions in which perhaps these cells malfunction, increasing blood pressure in the body, and also increasing it in the brain resulting in migraines, headaches, and strokes.
