that the utricle and saccule, also known as the otoliths, directly affected brain blood flow regulation, independent of other factors, such as blood pressure.
Dr Serrador explained why the connection may exist: "Standing up places the head above the heart and thus makes it harder to provide blood flow to the brain.
"Having a connection between the otoliths, which tell us that we are standing, and the cerebrovasculature may be part of the adaption that allows us to maintain our brain blood flow when upright.
"The knowledge gained from this study might lead to new treatment options for these conditions."
