Trace recordings of A: Control (Cont), B: UFP 512 (1 μM), C: TTX (1 μM) and D: TTX+UFP 512. E–G are statistical results of each recording parameter. *p <0.05, **p <0.01, ***p <0.001 as compared with the controls; ##p <0.01, ###p <0.001 vs. UFP 512. Note that TTX (1 μM) greatly attenuated anoxic K+ derangement (n=13). UFP 512 (1 μM) could not further attenuate anoxia-induced K+ derangement in the cortical slices with co-perfusion of TTX (n=14).
