Fig. 5. Interaural difference plot modeling the output of a binaural difference
(EI) neuron in the four lizard species Mabuya (A), Leiolepis
(B), Ctenosaura (C) and Gekko (D). The eardrum vibration
data set is subtracted from its reflection along the body axis. Other details
as in Fig. 3, except that the
colour scale now is relative interaural differences in dB. The line plots in
the left and right column show relative interaural differences
(y-axis) as a function of direction (x-axis) at three
frequencies (1000, 2000 and 3000 Hz, arrows). Note that the interaural
differences include the effect of sound diffraction by the body of the
lizard.
