Fig. 5. Typical impulse responses (A,B) with corresponding calculated power spectra
(C,D) recorded from single cells in a male Caligo memnon (blue) and a
male Morpho peleides (red) in (A,C) light-adapted (LA) and (B,D)
dark-adapted (DA) conditions. The integration time and time-to-peak of these
recordings are: C. memnon
tLA=9 ms,
tDA=18 ms,
p,LA=17 ms,
p,DA=31 ms, and M. peleides
tLA=8 ms,
tDA=15 ms,
p,LA=16 ms,
p,DA=26 ms. The corresponding
corner frequencies are: C. memnon fc,LA=33 Hz,
fc,DA=16 Hz and M. peleides fc,LA=42 Hz,
fc,DA=23 Hz.
