    Chunk versus point sampling: visual imaging in a small insect (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-11-05
    Description: The eyes of strepsipteran insects are very unusual among living insects. In their anatomical organization they may form a modern counterpart to the structural plan proposed for the eyes of some trilobites. Externally they differ from the usual "insect plan" by presenting far fewer but much larger lenses. Beneath each lens is its own independent retina. Anatomical and optical measurements indicate that each of these units is image-forming, so that the visual field is subdivided into and represented by "chunks," unlike the conventional insect compound eye that decomposes the visual image in a pointwise manner. This results in profound changes in the neural centers for vision and implies major evolutionary changes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Buschbeck, E -- Ehmer, B -- Hoy, R -- New York, N.Y. -- Science. 1999 Nov 5;286(5442):1178-80.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Neurobiology and Behavior, Mudd Hall, Cornell University, Ithaca, NY 14853, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10550059" target="_blank"〉PubMed〈/a〉

    Harmonic convergence in the love songs of the dengue vector mosquito (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-01-10
    Description: The familiar buzz of flying mosquitoes is an important mating signal, with the fundamental frequency of the female's flight tone signaling her presence. In the yellow fever and dengue vector Aedes aegypti, both sexes interact acoustically by shifting their flight tones to match, resulting in a courtship duet. Matching is made not at the fundamental frequency of 400 hertz (female) or 600 hertz (male) but at a shared harmonic of 1200 hertz, which exceeds the previously known upper limit of hearing in mosquitoes. Physiological recordings from Johnston's organ (the mosquito's "ear") reveal sensitivity up to 2000 hertz, consistent with our observed courtship behavior. These findings revise widely accepted limits of acoustic behavior in mosquitoes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2847473/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2847473/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cator, Lauren J -- Arthur, Ben J -- Harrington, Laura C -- Hoy, Ronald R -- R01 DC000103/DC/NIDCD NIH HHS/ -- R01 DC000103-34/DC/NIDCD NIH HHS/ -- New York, N.Y. -- Science. 2009 Feb 20;323(5917):1077-9. doi: 10.1126/science.1166541.

    Categorical perception of sound frequency by crickets (1996)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1996-09-13
    Description: Partitioning continuously varying stimuli into categories is a fundamental problem of perception. One solution to this problem, categorical perception, is known primarily from human speech, but also occurs in other modalities and in some mammals and birds. Categorical perception was tested in crickets by using two paradigms of human psychophysics, labeling and habituation-dishabituation. The results show that crickets divide sound frequency categorically between attractive (〈16 kilohertz) and repulsive (〉16 kilohertz) sounds. There is sharp discrimination between these categories but no discrimination between different frequencies of ultrasound. This demonstration of categorical perception in an invertebrate suggests that categorical perception may be a basic and widespread feature of sensory systems, from humans to invertebrates.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wyttenbach, R A -- May, M L -- Hoy, R R -- K05-MH1148/MH/NIMH NIH HHS/ -- R01-CD00103/CD/ODCDC CDC HHS/ -- T32-MN15793/MN/OMHHE CDC HHS/ -- etc. -- New York, N.Y. -- Science. 1996 Sep 13;273(5281):1542-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section of Neurobiology and Behavior, Cornell University, Ithaca, NY 14853-2702, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8703214" target="_blank"〉PubMed〈/a〉

    The evolutionary convergence of hearing in a parasitoid fly and its cricket host (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-11-13
    Description: Parasitism is a widespread and diverse life strategy that connects species throughout the animal kingdom. Female parasitoid flies of the genus Ormia must find a specific cricket host on which to deposit their parasitic maggots. To reproduce, female flies must perform the same task as female crickets: find a singing male cricket. These flies have evolved a unique hearing organ that allows them to detect and locate singing male crickets. Through evolutionary convergence, these flies possess a hearing organ that much more resembles a cricket's ear than a typical fly's ear, allowing these parasitoids to take advantage of the sensory ecological niche of their host.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Robert, D -- Amoroso, J -- Hoy, R R -- DC00103/DC/NIDCD NIH HHS/ -- New York, N.Y. -- Science. 1992 Nov 13;258(5085):1135-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section of Neurobiology and Behavior, Cornell University, Ithaca, NY 14853.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1439820" target="_blank"〉PubMed〈/a〉

    Initiation of behavior by single neurons: the role of behavioral context (1984)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1984-11-23
    Description: Flying crickets avoid sources of ultrasound, possibly echolocating bats, by making rapid steering movements that turn them away from the stimulus. Electrical stimulation of a single, identified sensory interneuron (Int-1) elicits avoidance steering; depressing its response to ultrasound abolishes avoidance steering. Int-1 is necessary and sufficient for this behavior but only while the cricket is in flight. Thus, the sufficiency of Int-1 for eliciting this behavior is contingent on behavioral context.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nolen, T G -- Hoy, R R -- New York, N.Y. -- Science. 1984 Nov 23;226(4677):992-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6505681" target="_blank"〉PubMed〈/a〉

    The cyclopean ear: a new sense for the praying mantis (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-02-14
    Description: The praying mantis, thought to be deaf, possesses a sensitive and specialized acoustic sense. Neural recordings show that the auditory system responds primarily to ultrasound between 25 and 45 kilohertz with thresholds of 55 to 60 decibels. Other insects with auditory tympana possess paired, laterally placed ears; the mantis has only a single ear that is located in the ventral midline between the metathoracic legs. Some species of mantis abruptly and dramatically alter their flight path when stimulated with ultrasonic pulses, suggesting a behavioral response to insectivorous echo-locating bats.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yager, D D -- Hoy, R R -- New York, N.Y. -- Science. 1986 Feb 14;231(4739):727-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3945806" target="_blank"〉PubMed〈/a〉

    Hawaiian courtship songs: evolutionary innovation in communication signals of Drosophila (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-04-08
    Description: In Hawaii, flies of the genus Drosophila have undergone spectacular adaptive radiation, resulting in the evolution of more than 500 species of Drosophila that are found nowhere else on earth. This taxonomic uniqueness is reflected in behavior and morphology. Hawaiian Drosophila sing songs, as do continental Drosophila; however, the Hawaiian songs have diverged strongly in form and mechanism of production. The click-song of D. fasciculisetae's (Maui) has a carrier frequency an order of magnitude higher than those reported in familiar continental species, such as D. melanogaster (170 hertz). Drosophila fasciculisetae's song resembles a cicada's more than a fly's song. The song of D. cyrtoloma (Maui) has a complex pulse rhythm more typical of crickets than flies. The pulse song of D. silvestris (Hawaii) closely resembles that of D. melanogaster in both pulse rhythm and carrier frequency, but D. melanogaster sings by vibrating its wings, whereas D. silvestris sings through abdominal vibrations. These mechanisms are radical departures from the continental wing song mechanism and are further examples of the remarkable behavioral innovation that has occurred in the Drosophila of Hawaii during their evolutionary transit through these islands.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hoy, R R -- Hoikkala, A -- Kaneshiro, K -- New York, N.Y. -- Science. 1988 Apr 8;240(4849):217-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section of Neurobiology and Behavior, Cornell University, Ithaca, NY 14853.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3127882" target="_blank"〉PubMed〈/a〉
