A, representative samples from MNCs from a sham and RVH rat showing that blockade of glutamate transporters (TF‐TBOA, 500 nm) induced an inward shift in the holding current (I
TF‐TBOA). B, summary data of mean I
TF‐TBOA in MNCs from sham and RVH rats (n = 15 and 12, respectively). C, representative examples of I
A (command step to −20 mV) before and during TF‐TBOA in the same sham and RVH rat as in A. Time points 1 and 2 correspond to those shown in A. D, summary data of mean I
A amplitude evoked before and during TF‐TBOA in MNCs from sham and RVH rats (n = 15 and 12, respectively). *
P < 0.02, **
