Conclusion: In the #Brain 🧠, #Microvasculature is not #Innervated like in #PeripheralTissue. #PrecapillarySphincters and/or #FirstOrderCapillaries are central to #NeurovascularCoupling, which may be enhanced by perpendicular alignment of #
#MyoendothelialJunctions are 🔗s between #MuralCells and #Endothelia, elsewhere separated by the #BasementMembrane. I show how #Brain #PrecapillarySphincters are 🔥spots for these junctions (yellow dots), like Rhodin showed in 🐇 #Periphera
‼️Importantly, #PrecapillarySphincters exist where a #Capillary branches from a much larger #Arteriole (≈upper cortical layers) but not when there is a more gradual transition (≈lower cortical layers). (3/15)
