Encoding of amplitude modulations by auditory neurons of the locust: influence of modulation frequency, rise time, and modulation depth.

There was a significant trend towards a better resolution of AM depth in the RAM condition (minimal modulations thresholds: −27.4 ± 6.5 compared to −24.5 ± 6.1, P = 0.0012, mean ± SD; Wilcoxon paired test, two tailed), i.e. with a steeply rising stimulus onset already somewhat shallower modulations led to a significant locking of spikes to the stimulus envelope; the corresponding differences are, however, biologically probably not very relevant: minimal modulations depths of 4.3% (RAM) and 5.9% (SAM).

A weakly significant decrease of max vector strength was observed between primary-like local and ascending neurons (ANOVA and Tukey–Kramer post hoc test: P < 0.05; all other comparisons: n.s.).
