Comparisons Between Electrosensory and Mechanosensory Lateral Line Systems

摘要: A volume on the lateral line would be incomplete without a consideration of its closely allied sense, electroreception. Electroreception is usually considered specialized sense (Dijkgraaf 1962; Lissmann 1967; Szabo 1974). The marked similarities between mechanosensory (hereafter referred to as line) and electrosensory systems, including embryology morphology receptors, receptor innervation distribution, CNS anatomy, are generally appreciated held by most reflect close evolutionary relationship these so-called lateralis senses. Since discovery electroreception 30 years ago in weakly electric teleost fishes (Lissmann 1958; Bennett Grundfest 1959; Bullock et al. 1961; Fessard 1961), favored hypothesis has been that electroreceptors evolved derivatives preexisting neuromasts 1958, Mullinger 1964; 1971). Major support for this was phylogenetic distribution two senses it then known. In last line, published 20 ago, (1967) stated case simply: “The ordinary neuromast rule, ampullary organ [electroreceptor] exception.”
