From: Mechanisms of astrocytic K+ clearance and swelling under high extracellular K+ concentrations
The contributions of ion channels and transporters to the changes of intracellular ion concentrations in astrocytes. Ion flux of Na+ (row 1, red lines), K+ (row 2, blue lines), and Cl− (row 3, yellow lines) were simulated using the same conditions as in Fig. 3. Results are shown for the total of all channels and transporters (column 1), Na,K-ATPases (column 2), NKCCs (column 3), KCCs (column 4), KIR channels, and I Cl,passive (column 5). Positive values (upward) correspond to an outward flux of ions. Thin lines represent zero levels
