Figure 6.

Paradoxical effects of presenting ipsilateral signals monaurally compared to the effects of presenting the same ipsilateral signals binaurally. Increases in amplitudes of the ipsilaterally evoked EPSPs with intensity were in the exact opposite direction to the reduced EPSP amplitudes evoked by the same ipsilateral intensities presented binaurally. Lines connect mean EPSP amplitudes of 13 EI cells. The EPSPs of binaural signals that evoked spikes were measured after spikes were filtered from recordings. Error bars show standard error of the mean.
