当第一次对洛仑兹尼壶腹进行实验研究时（见参考文献1），人们认为它和听外侧系统的其他器官一样对机械刺激敏感。但是当Sand 2记录他们神经的电活动时，他发现对机械刺激没有反应，而只有对热刺激的反应;当温度稍微改变时，脉冲频率会发生大的瞬时变化。壶腹的功能是热接收，这一观点一直被广泛接受，但这一观点从未得到行为学实验的证实。
WHEN the ampullæ of Lorenzini were first studied experimentally (see ref. 1), they were considered to be sensitive to mechanical stimuli like the other organs of the acoustico-lateralis system. But when Sand2 recorded the electrical activity in their nerves, he found no response to mechanical stimuli but only to thermal stimuli; large, transient changes in impulse frequency occurred when the temperature was changed slightly. Ever since it has been widely accepted3 that the function of the ampullæ is thermo-reception, but this opinion has never been confirmed by behavioural experiment.
