Fig. 5.

Vector strengths of phase locking to the f0 of the contralateral stimulus (A and C) and the f0 of the ipsilateral stimulus (B and D) for the units shown in Fig. 3. A and B: EI unit shown in Fig. 2, A and B, and Fig. 3, A–C. C and D: EE unit shown in Fig. 2, C and D, and Fig. 3, D–F. Plots are shown as a function of ipsilateral level with contralateral level as the parameter: 60 dB, 50 dB, and 40 dB.
