Echo responses in experiment 2. (A) Example of a monocular IRF in one observer (measured at electrode POz). (B) Comparison of echo envelopes at electrode POz, measured from binocular, single-sequence stimulation (experiment 1) and dichoptic, two-sequence stimulation in experiment 2. Based on the reduced SNR, we limited our analysis to lags 250–750 ms in experiment 2. (C) Topographical distribution of echo power in the control session. Electrode POz (marked x) was selected as ROI for the echo analyses in experiment 2. As before, the topographical maps are aligned such that the (designated) deprived eye is right; the arrows mark the side of stimulation.
