Researcher discovers previously rejected function in the brain’s blood vessels

by  University of Copenhagen Allegedly, they should not exist in the brain, the so-called precapillary sphincters—a kind of squeezing ‘muscle clamp’ between the larger and smaller vessels of the bloodstream. Close-up of precapillary sphincter (the strong red mark in the middle of the greenly marked blood flow) from two-photon microscope. According to the research results, these...
