Fig. 9. Removal of mirror regions. Analysis of calls from one individual before (A)
and after (B) removal of the membranes of Areas 1, 3 and 4 of the right
tegmen. Oscillograms are shown in the left, power spectra in the middle and
spectrograms on the right. Red arrows indicate the same frequency in the
spectral displays (middle and right). After removal of Areas 1, 3 and 4, there
was a decrease in the relative intensity of the fundamental and an increase in
harmonic frequency components.
