The heart of the pteropodial mollusc Clione limacina is innervated by the median nerve arising from the left abdominal ganglion. Five neurons sending axons to the heart have been identified in the Clione central nervous system with retrograde cobalt or Lucifer yellow staining. Neuron H1 located in the left pedal ganglion evoked heart excitation. Three neurons H2-H4 located in the medial part of the left abdominal ganglion caused heart inhibition. Neuron H5 located in the caudal part of the left abdominal ganglion did not affect the heart. The activity of the efferent heart neurons was found to be related to the operation of the locomotor rhythm generator. Spontaneous or reflex suppression of the locomotor rhythm generation was accompanied by inhibition of neuron H1 and excitation of neurons H2-H4. Such behavior of the efferent heart neurons ensures a positive correlation between heart and locomotor activities in Clione limacina.
翼足类软体动物海天使的心脏由发自左腹神经节的正中神经支配。运用逆行钴染或荧光黄染色法，在海天使的中枢神经系统中已鉴定出五个向心脏发送轴突的神经元。位于左足神经节的神经元H1可诱发心脏兴奋。位于左腹神经节中部的三个神经元H2 - H4会导致心脏抑制。位于左腹神经节尾部的神经元H5对心脏没有影响。已发现传出性心脏神经元的活动与运动节律发生器的运作有关。运动节律产生的自发或反射性抑制伴随着神经元H1的抑制以及神经元H2 - H4的兴奋。传出性心脏神经元的这种行为确保了海天使心脏活动与运动活动之间的正相关关系。
