电感受是一种古老的脊椎动物感觉，具有令人着迷的进化历史，涉及多次损失以及硬骨鱼中至少两次的独立进化。我们回顾了不同脊椎动物群体中电感受器的系统发育分布以及电感受器的形态和神经支配。我们总结了我们实验室最近的工作，该工作证实了非硬骨类有颌脊椎动物壶腹电感受器的同源性，结合之前发表的工作，表明这些电感受器是从侧线基板胚胎衍生的。最后，我们回顾了解释硬骨鱼内电感受分布的假设，包括硬骨鱼壶腹部和结节性电感受器通过侧线神经丘中机械感觉毛细胞的修饰而进化的假设。我们的结论是，需要对硬骨鱼电感受器发育进行进一步的实验工作来检验这些假设。
Electroreception is an ancient vertebrate sense with a fascinating evolutionary history involving multiple losses as well as independent evolution at least twice within teleosts. We review the phylogenetic distribution of electroreception and the morphology and innervation of electroreceptors in different vertebrate groups. We summarise recent work from our laboratory that has confirmed the homology of ampullary electroreceptors in non-teleost jawed vertebrates by showing, in conjunction with previously published work, that these are derived embryonically from lateral line placodes. Finally, we review hypotheses to explain the distribution of electroreception within teleosts, including the hypothesis that teleost ampullary and tuberous electroreceptors evolved via the modification of mechanosensory hair cells in lateral line neuromasts. We conclude that further experimental work on teleost electroreceptor development is needed to test such hypotheses.
