Li⁺ slows the mEPSC rise in the presence of KYN. A, Cumulative probability histogram of mEPSC rise times from a single cell in 60 nm NBQX in Na⁺ (solid line) and Li⁺ (dotted line). B, mEPSC rise times from four cells, combined, in NBQX with Na⁺ (solid line;n = 1017) and Li⁺ (dotted line; n = 866). C, Cumulative probability histogram of mEPSC rise times from the same cell as in A in 200 μm KYN with Na⁺ (solid line) and Li⁺ (dotted line). D, mEPSC rise times from the same six cells as in B, combined, in KYN with Na⁺ (solid line; n = 1150) and Li⁺(dotted line; n = 806).
