Fig. 6. Effects of body temperature on tuning, sensitivity and latency evaluated
from recordings of the auditory nerve of the cicada T. josei. (A)
Averaged and (B) example tuning curves measured at different temperatures
ranging from 16°C to 28°C. There is a strong effect in the
characteristic frequency and sensitivity in the range 3–8 kHz, but not
at higher frequencies. Error bars indicate the standard deviation. (C)
Sensitivity at the characteristic frequency measured in the 10 cicadas, from
19 recordings (see Table 2),
which exhibited increased sensitivity with temperature. The lines connect the
sensitivities evaluated from each auditory nerve recording. (D) Dependence of
latency on temperature measured in 19 cicadas. Latencies were measured 20 dB
above threshold and decreased with increasing temperature.
