Resting Ptiss,O2 in the ONL and GL. A, Schematics. A fluorescent oxygen electrode (fluorescein) was placed at several sites in the GL and ONL. B, Ptiss,O2 (normalized to the GL value) as a function of distance from the glomerular center. Each value is an average of three to six measurements. Note that moving the electrode back and forth (n = 3 rats) may slightly affect the oxygen measurements. The symbols indicate different experiments. C, At resting state, Ptiss,O2 is similar in both the GL and the ONL.
