Figure 4.

Ensemble NMDA currents were regulated by the activation of remote NMDA receptors. Shown are examples of the alignment of vertically flipped super cluster current traces at the start of the first openings of superclusters recorded before (control) and during the activation of remote NMDA receptors in neurons bathed with an extracellular solution containing 10 mm Na+ (A, C) or 200mm Na+ (B, D). Recording pipettes were filled with the same extracellular solution used for bathing neurons except that it contained 10 μm NMDA. c, Closed level; o, open level. E, The corresponding ensemble currents produced by the summation of 100 and 95 consecutive superclusters recorded before (Control) and during the activation of remote NMDA receptors (NMDAR), examples of which are shown in A and C, respectively. F, The corresponding ensemble currents produced by the summation of 114 and 153 consecutive superclusters recorded before (Control) and during the activation of remote NMDA receptors (NMDAR), examples of which are shown in B and D, respectively. The ensemble currents were normalized by their peak amplitudes and superimposed to show the difference between the currents.
