Figure 2. Light-evoked vasodilatation is not reduced in Kir4.1 knockout (KO) mice despite the absence of K+ currents in retinal glial cells.

Figure 2

A, flickering light stimulation evokes vasodilatation of similar amplitude in both wild-type (WT) and Kir4.1 knockout mice.

B, Ba2+-sensitive current–voltage relations of Müller cells from Kir4.1 WT and KO mice. Ba2+-sensitive inward current is completely absent in the KO cell.
