Fig. 2. Recording examples of activity in a pair of omega cells in responseto conspecific chirps (red) and the masker (blue).with (A) only the chirp presented from ipsilateral, (B) the signal and maskerpresented from ipsilateral and (C) after a shift of the masker to contralateral.(D) Monaural system, with the signal presented from ipsilateral and the masker (A–C) Binaural system,from contralateral.
