Tonotopic organization of auditory receptors of the bushcricket Pholidoptera griseoaptera (Tettigoniidae, Decticinae)
Identifying receptor cells revealed an interindividual variability of tuning and central projections of auditory receptors of the bushcricket Pholidoptera griseoaptera, which was broadly tuned and less sensitive than those of the crista acustica.
Processing of auditory information in insects
The aim of this review is to summarize and compare the present concepts of auditory processing by relating behavioral performance to known neuronal mechanisms, and demonstrates that closely related species often use different combinations of temporal parameters in their recognition systems.
Auditory interneurones in the metathoracic ganglion of the grasshopper Chorthippus biguttulus. I, Morphological and physiological characterization
A comparison of branching patterns and physiological properties indicates that auditory interneurones of C. biguttulus are homologous with those described for the locust.
Diversity of intersegmental auditory neurons in a bush cricket
Various auditory interneurons of the duetting bush cricket Ancistrura nigrovittata with axons ascending to the brain are presented and a new type of ascending neuron with posterior soma in the prothoracic ganglion (AN4) is identified.
A new biophysical method to determine the gain of the acoustic trachea in bushcrickets

A method is described for measuring the gain for sounds that propagate to the internal surface of the tympana in ears working as pressure difference receivers, and other methods, which in the past have been used for estimating the gain of sound pathways inside animal bodies are compared.
Convergent evolution of insect hearing organs from a preadaptive structure

Physiological and anatomical data indicate a preadaptive–sound–insensitive, but vibration–sensitive scolopidial chordotonal organ in non–hearing flies.
Singing and hearing in a Tertiary bushcricket
Some extremely well preserved stridulatory and hearing organs of the oldest known bushcrickets from the lowermost Tertiary sediments of Denmark indicate that males sang with a broadband frequency spectrum, and it is likely that both sexes could hear ultrasound.
Sex-specific spectral tuning for the partner's song in the duetting bushcricket Ancistrura nigrovittata (Orthoptera: Phaneropteridae)
The song of the male bushcricket Ancistrura nigrovittata consists of a sequence of verses. Each verse comprises a syllable group, plus, after about 400 ms a single syllable serving as a trigger for…
Songs and the Function of Song Elements in Four Duetting Bushcricket Species (Ensifera, Phaneropteridae, Barbitistes)
The structure of male songs and the timing of female replies with respect to the male songs are described for four species of the palaearctic bushcricket genus Barbitistes and a close phylogenetic relationship between B. constrictus and B. serricauda is assumed.

A simple mechanistic model is presented to address the timescale-invariant recognition of temporal stimulus sequences in insects that use rhythmic acoustic communication signals for mate finding and suggests a new computational role for feedforward inhibition and underscores the power of parallel signal processing.
