Figure 6

Mutual information rate (lower bound) between the D signal and the output spike train when the modulation amplitude ϵF is varied, both for the case considered above (both signals in the same frequency range) and for the case where the F signal has been shifted to values between 10 and 20 Hz. The shifted signal is clearly more effective at enhancing information transmission about the D signal. Other parameters as in Figures 4, 5.
