Organization of a sensory neuropile in the auditory pathway of two groups of orthoptera
The anterior intermediate sensory neuropile (aISN) is a prominent neuropile in the ventral nerve cord of locusts and bushcrickets. Previous studies have shown that it receives its main sensory inputExpand

Environmental and Biological Constraints for the Evolution of Long-Range Signalling and Hearing in Acoustic Insects
A number of insects use sound signals for the attraction of mates and in aggressive interactions between males. I discuss two constraints which may have shaped both the design of long-range signals,Expand

Strategies for hearing in noise: peripheral control over auditory sensitivity in the bushcricket sciarasaga quadrata (Austrosaginae: tettigoniidae)
The carrier frequency of the call of the Australian bushcricket Sciarasaga quadrata is unusually low for tettigoniids at 5 kHz. The sound transmission measured in the habitat of the insect reflectsExpand

Evolutionary transition from stretch to hearing organs in ancient grasshoppers
Ears of modern insects occur on a wide variety of body parts and are thought to have evolved from ubiquitous stretch or vibration receptors. This relationship, based on comparative anatomy andExpand

Solutions to the Cocktail Party Problem in Insects: Selective Filters, Spatial Release from Masking and Gain Control in Tropical Crickets
Background Insects often communicate by sound in mixed species choruses; like humans and many vertebrates in crowded social environments they thus have to solve cocktail-party-like problems in orderExpand

Tonotopic organization of the auditory neuropile in the bushcricket Tettigonia viridissima
Invertebrate central neural structures, especially sensory or motor neuropiles, have proved rather intractable to conventional physiological analysis as they are considered to have a diffuse orExpand

Serial hearing organs in the atympanate grasshopper Bullacris membracioides (Orthoptera, Pneumoridae)
In different insect taxa, ears can be found on virtually any part of the body. Comparative anatomy and similarities in the embryological development of ears in divergent taxa suggest that they haveExpand

Synaptic mechanisms of monaural and binaural processing in the locust
Abstract (1) Responses of auditory interneurones were recorded intracellularly within the metathoracic ganglion of the locust when stimulating each tympanic membrane with a piezoelectric transducer.Expand

Spatial segregation of synaptic inputs and outputs in a locust auditory interneurone
Using intracellular injection of cobalt, processing for electron microscopy, and using on‐section silver intensification, we have investigated the distribution of synapses on the metathoracicExpand

Neural Mechanisms for Acoustic Signal Detection under Strong Masking in an Insect
Communication is fundamental for our understanding of behavior. In the acoustic modality, natural scenes for communication in humans and animals are often very noisy, decreasing the chances forExpand
