... of particle velocity hearing lies between 13 and 20 dB sound particle velocity level (SVL) (95% confidence interval). A conservative estimate of 20 dB SVL (i.e. <0.5 µm s −1 particle velocity) is 12–26 dB lower than most of the published electrophysiological measurements from the Johnston's organ...

...Dmitry N. Lapshin; Dmitry D. Vorontsov ABSTRACT The paired auditory organ of the mosquito, the Johnston's organ (JO), being the receiver of the particle velocity component of sound, is directional by its structure. However, to date almost no physiological measurements of its directionality have...

... Phonotaxis Insect Johnston's organ Sound localization is a basic function of auditory systems. In organisms with tympanal ears, sound localization depends primarily on inter-aural differences in the amplitude of eardrum vibrations, as well as inter-aural differences in the timing of those...

... Insect hearing Johnston's organ The complexity of malaria epidemiology and control is due in part to the remarkable degree of genetic variation among the species of the genus Anopheles ( della Torre et al., 2005 ; Coetzee et al., 2013 ). This is particularly evident in the species complex...

.... RFM features are highly consistent, even in response to artificial tones that do not carry the multi-harmonic components of natural female flight tones. Comparison between audiograms of the robust RFM behaviour and the electrical responses of the auditory Johnston's organ (JO) reveals that the male JO...

... organs also provides a mechanosensory feedback relevant for flight stabilization. However, few studies have addressed how the individual units, or scolopidia, of the Johnston's organs encode these antennal vibrations and communicate it to the brain. Here, we characterize the encoding properties...

... in Johnston's organ are required to guide upwind turns. Flight responses to an odor depend on the identity of the ORNs that are active, meaning that these behaviors involve odor discrimination and not just odor detection. Flight modulation can begin rapidly (within about 85 ms) after the onset of olfactory...

... and the antennal chordotonal organs (Johnston's organs) provide sufficient information about the geometry of an object to elicit the observed change in locomotor behavior. Only when both these sensory systems were impaired did flies not show the behavioral preference for the tall, steep objects. Much...

... and is likely subserved, at least in part, by the Johnston's organs, chordotonal organs in the antennae also involved in near-field sound detection. These wind-mediated responses may help to explain how flies are able to fly forward despite visual responses that might otherwise inhibit this behavior. Expanding...
