Figure 3 : (a,b) Combined effects of NMDA and ethanol on the amplitude of the ERG b- and d-wave.

Results of both control experiments (open symbols) and test experiments (filed symbols) are represented. The times, when the perfusion was switched to NMDA and NMDA+ethanol solution, are indicated by arrows. All designations are the same as Figures 1a and 1b. (c) Original ERG records (b- and d-wave), obtained during the perfusion with Ringer solution in the control period (upper row), NMDA, NMDA+Ethanol and Ringer solution in the recovery period (bottom row). It can be seen that the positive d-wave disappeared during combined NMDA+ethanol perfusion and reappeared again in the recovery period. Calibration: time –0.2 s; amplitude –50μV. (d) Original ERG records obtained from an experiment where a small positive d-wave was preserved during the combined NMDA+ethanol perfusion. Calibration: time –0.2 s; amplitude –0 μV.
