*  capillary - Dwight Bergles Laboratory
This hypothesis has been challenged, as arteriole dilation can occur in the absence of glial Ca(2+) signaling. We address this ... We find that sensory stimulation results in Ca(2+) increases in the glial endfeet contacting capillaries, but not arterioles, ... In IP3R2(-/-) mice, where glial Ca(2+) signaling is reduced, light-evoked capillary, but not arteriole, dilation is abolished. ... The results show that, independent of arterioles, capillaries actively dilate and regulate blood flow. Furthermore, the results ...
