Crickets carry wind-sensitive mechanoreceptors on their cerci, which, in response to the airflow produced by approaching predators, triggers escape reactions via ascending giant interneurons (GIs). Males also activate their cercal system by air currents generated due to the wing movements underlying sound production. Singing males still respond to external wind stimulation, but are not startled by the self-generated airflow. To investigate how the nervous system discriminates sensory responses… Expand
Impact of cercal air currents on singing motor pattern generation in the cricket (Gryllus bimaculatus DeGeer).
The disruptive effects of air stimuli on the fictive singing pattern and the inhibitory response of the singing interneuron point toward the cercal system being involved in initiating avoidance responses in singing crickets, according to the established role of cerci in a predator escape pathway.

Feedforward discharges couple the singing central pattern generator and ventilation central pattern generator in the cricket abdominal central nervous system
The authors' recordings suggest that the two centrally generated motor patterns are coordinated by reciprocal feedforward discharges from the singing-CPG to the ventilation-C PG and vice versa. Expand
Auditory modulation of wind-elicited walking behavior in the cricket Gryllus bimaculatus
The results suggest that the cricket nervous system is able to integrate auditory and air-puff stimuli, and modulate the wind-elicited escape behavior depending on the acoustic context, suggesting a multisensory interaction between the auditory and cercal sensory systems. Expand
Evolution of a Communication System by Sensory Exploitation of Startle Behavior
This work found that female lebinthines, instead of approaching singing males, produce vibrational responses after male calls, and males track the source of vibrations to find females, demonstrating how sensory exploitation of anti-predator behavior can evolve into a communication system that benefits both senders and receivers.

Neuroethology of acoustic communication in field crickets - from signal generation to song recognition in an insect brain
This review aims to summarize the current knowledge of the neurobiological basis underlying the acoustic communication for mate finding in field crickets with emphasis on the recent research progress to understand the neuronal networks for motor pattern generation and auditory pattern recognition of the calling song in Gryllus bimaculatus.

Female perception of copulatory courtship by male titillators in a bushcricket
The hypothesis that the male titillators in these bushcrickets may serve as copulatory courtship devices to mechanically stimulate the female genitalia to reduce resistance behaviour is supported. Expand
An auditory feature detection circuit for sound pattern recognition
This work shows how five neurons in the brain of females form an auditory feature detector circuit for the pulse pattern of the male calling song that provides the basis for auditory mate recognition in field crickets and reveals a principal mechanism of sensory processing underlying the perception of temporal patterns.

Electrophoresis of polar fluorescent tracers through the nerve sheath labels neuronal populations for anatomical and functional imaging
A new method for neuronal labelling by electrophoretic dye delivery from a suction electrode directly through the neuronal sheath of nerves and ganglia in insects is described, providing a new tool for studying how stimuli are processed in peripheral and central sensory pathways. Expand

Anatomy and physiology of identified wind-sensitive local interneurons in the cricket cercal sensory system
A group of wind sensitive local interneurons in the terminal abdominal ganglion of the cricket Acheta domesticus were identified and studied using intracellular staining and recording techniques and directionally sensitive; their response amplitudes varied with wind stimulus orientation. Expand
Cellular basis for singing motor pattern generation in the field cricket (Gryllus bimaculatus DeGeer)
The singing behavior of male crickets allows analyzing a central pattern generator (CPG) that was shaped by sexual selection for reliable production of species‐specific communication signals. AfterExpand
Wind-evoked escape running of the cricket Gryllus bimaculatus II. Neurophysiological analysis
Modulated spike activity in ascending cells during walking suggests a role in tuning the thoracic motor centres for a central walking command, and it is proposed that descending interneurones from the suboesophageal ganglion coordinate different behavioural rhythms. Expand
Response of the cercus-to-giant interneuron system in crickets to species-specific song
With simultaneous recording from both sides of the abdominal nerve cord, synchronous or alternating discharges can be detected, correlated either with syllables or intervals, therefore allowing the transmission of the time patterns of calling song, rivalry song and even courtship song. Expand

By responding to cercal movements sufficient to also activate filiform hairs, and by mediating conductance changes in both the presynaptic terminals of filiform afferents and the postsynaptic membranes of interneurons, the PAD unit desensitizes a pathway to movement-generated afferent input, and ensures that the locust remains sensitive to external wind stimuli.

Pre- and postsynaptic inhibition of identified giant interneurons in the cricket (Acheta domesticus)
Two interneurons which had not previously been studied in detail were found to be influenced markedly by inhibitory inputs, and the cerecl receptor-to-giant interneuron pathway was inhibited presynaptically. Expand
Differing afferent connections of spiking and nonspiking wind-sensitive local interneurons in the terminal abdominal ganglion of the cricket Gryllus bimaculatus
It is found that the spiking and the non-spiking local interneurons in the cereal sensory system differ not only in their membrane properties, but also in their afferent connections, and it is concluded that their differing connectivity to the sensory afferents will associate them with different roles in signal processing.

A corollary discharge mechanism modulates central auditory processing in singing crickets.
The corollary discharge prevents auditory desensitization in stridulating crickets and allows the animals to respond to external acoustic signals during the production of calling song. Expand
Corollary discharge to cockroach giant interneurones
Evidence is reported that some of these giants are directly excited during walking by neural input which may represent corollary discharge from motor centres in the thorax, and which may aid the insect in handling reafferent input. Expand
