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. Similarities in the structure of the anterior lateral line nerves and medullary organization between lampreys and several primitive jawed fishes indicate that the electroreceptive systems are homologous in these taxa. Thus electroreception was probably present in the earliest vertebrates ancestral to both agnathans and gnathostomes.
七鳃鳗大脑对弱电场的诱发电位和单位反应表明，七鳃鳗拥有与其他电感受性鱼类一样敏感的电感觉系统。在背髓、中脑半规管隆起和视顶盖中记录到了电感觉反应。七鳃鳗与几种原始有颌鱼类的前侧线神经结构和髓质组织的相似性表明，这些类群中的电感受系统是同源的。因此，电感受可能存在于无颌类和有颌类共同的最早脊椎动物祖先中。
