Results: In this study of the #MICrONS 🐭👁️-cortex 3D #ElectronMicroscopy dataset, I show how the shape of #Contractile #MuralCells transition from #PenetratingArteriole to #PrecapillarySphincter to #Capillaries. Vascular lumen = blue, mural cells = various colors (5/15)
The function 🧑‍🔧 of the #PrecapillarySphincter is to control the #BloodFlow to the #Capillaries, securing adequate distribution of blood flow between the upper and lower cortical layers. For more, check these🧵: https://bit.ly/3hUEytP and https://tinyurl.com/4e2w3x9n (4/15)
