Physiological properties of gill filament and gill raker mechanoreceptors in the gills of spontaneously breathing carp, Cyprinus carpio L., were analysed. Stroking stimuli applied to gill filaments elicited a phasic mechanoreceptive response, which was recorded from neurons in the epibranchial ganglia. Sustained deflection resulted in a short on-off response. The same neurons were also activated by slight movements of lamellae on a gill filament. The receptive field extended over all the lamellae of one filament at most, but generally covered a small part of it, including both dorsal and ventral lamellae. Deflection of gill rakers also elicited a brief response in epibranchial ganglion neurons. The threshold of both filament-related and gill raker mechanoreceptors was relatively high. They did not respond during normal respiration. It was therefore argued that these receptors do not function in normal respiratory control, but rather serve against mechanical damage from excessive pressure or particles in the water.
对自然呼吸的鲤鱼（Cyprinus carpio L.）鳃中鳃丝和鳃耙机械感受器的生理特性进行了分析。施加于鳃丝的抚摸刺激引发了一种相位性机械感受反应，该反应由鳃上神经节中的神经元记录下来。持续的偏转导致了短暂的开-关反应。同一神经元也会因鳃丝上薄片的轻微移动而被激活。感受野最多覆盖一根鳃丝的所有薄片，但通常只覆盖其中一小部分，包括背侧和腹侧薄片。鳃耙的偏转也会在鳃上神经节神经元中引发短暂反应。与鳃丝相关的机械感受器和鳃耙机械感受器的阈值都相对较高。它们在正常呼吸过程中没有反应。因此有人认为，这些感受器在正常呼吸控制中不起作用，而是用于防止来自水中过大压力或颗粒的机械损伤。
