Electroreception and electrolocation in platypus [PDF]

Nature, 1986
Electroreceptors with sensitivity in the microvolt range, which mainly function to detect live prey, are well known in phylogenetically old fishes and some amphibians. In African mormyriform and South American gymnotiform fishes this sense has evolved to an active system using an electric organ as a source for impedance measurement of the environment ...

Evolution of electroreception

Trends in Neurosciences, 1982
Abstract Recent evidence shows that the taxonomic distribution of electroreception is greater than was previously thought. This knowledge permits new speculation about the evolution of this sense, a topic already discussed in limited aspects by Lissman 18 and Hopkins 14 .

Phase Sensitivity in Electroreception

Science, 1978
The gymnotoid electric fish Hypopomus artedi discriminates between electric stimulus pulses with identical spectral amplitudes but different spectral phase functions. Behavioral results can be explained on the assumption that electroreception is based on a linear filter, approximately matched to the species ...

Electroreception in Lampreys: Evidence That the Earliest Vertebrates Were Electroreceptive

Science, 1981
Evoked potential and unit responses from the lamprey brain to weak electric fields demonstrate that lampreys have an electrosensory system as sensitive as those of other electroreceptive fishes. Electrosensory responses were recorded in the dorsal medulla, the midbrain torus semicircularis, and the optic tectum.

Electroreception in the Ratfish ( Hydrolagus colliei )

Science, 1980
Behavioral and neurophysiological experiments and anatomical work indicate that the ampullar structures on the head of fish of the subclass Holocephali are sense organs responsive to weak electric fields and are functionally and structurally homologous to the ampullae of Lorenzini in elasmobranchs.

The electroreceptive ampullary organs of urodeles

Cell and Tissue Research, 1983
The system of lateral-line organs in urodeles was examined by the use of various light- and electron-microscopical techniques. The results show that, in addition to the well-known mechanoreceptive neuromast organs, a second type of receptor can be identified. This second type of organ was presumably seen by earlier workers, but they seemingly failed to
