Changes in the ambient calcium concentration affected similarly both thermal and electrical sensitivity of electroreceptors of the Lorenzini ampullae in the skates. In Ca-free solution containing EGTA the sensitivity first decreased, then increased and after that blocking of synaptic transmission occurred. In Ca-rich solution both thermal and electrical sensitivity decreased. Changes of spontaneous activity occurred much later than those of evoked responses.
环境钙浓度的变化对鳐鱼洛伦兹壶腹电感受器的热敏感性和电敏感性产生了相似的影响。在含有乙二醇双四乙酸（EGTA）的无钙溶液中，敏感性先降低，然后升高，之后发生突触传递阻断。在富含钙的溶液中，热敏感性和电敏感性均降低。自发活动的变化比诱发反应的变化出现得晚得多。
