The mammalian external ear, for example, collects sound and spectrally alters it to increase sensitivity and improve the detection of directionality. In view of the morphological diversity of the lateral-line system across species and its accessibility to observation and experimental intervention, we sought to investigate the role of antennal structures on the response characteristics of the lateral line. The surface-feeding killifish Aplocheilus lineatus is able to hunt in darkness by detecting surface capillary waves with the lateral-line system atop its head. This cephalic lateral line consists of a stereotyped array of 18 mechanosensitive neuromasts bordered by fleshy ridges. By recording microphonic potentials, we found that each neuromast has a unique receptive field defined by its sensitivity to stimulation of the water's surface. The ridges help determine these receptive fields by altering the flow of water over each neuromast. Modification of the hydrodynamic environment by the addition of a supplemental ridge changes the pattern of water movement, perturbs the receptive fields of adjacent neuromasts and impairs the fish's localization ability. On the basis of electrophysiological, hydrodynamic and behavioral evidence, we propose that the ridges constitute a hydrodynamic antenna for the cephalic lateral line.<\/jats:p>","DOI":"10.1242\/jeb.051714","type":"journal-article","created":{"date-parts":[[2011,5,11]],"date-time":"2011-05-11T17:44:28Z","timestamp":1305135868000},"page":"1857-1866","source":"Crossref","is-referenced-by-count":25,"title":["A hydrodynamic sensory antenna used by killifish for nocturnal hunting"],"prefix":"10.1242","volume":"214","author":[{"given":"Jason S.","family":"Schwarz","sequence":"first","affiliation":[{"name":"Howard Hughes Medical Institute and Laboratory of Sensory Neuroscience, The Rockefeller University, 1230 York Avenue, New York, NY 10065, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tobias","family":"Reichenbach","sequence":"additional","affiliation":[{"name":"Howard Hughes Medical Institute and Laboratory of Sensory Neuroscience, The Rockefeller University, 1230 York Avenue, New York, NY 10065, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.
