We tested the ability of identified neurons from two different families of pulmonate molluscs to form specific connections in vitro. The presynaptic neuron chosen for this study was the giant dopamine cell of Lymnaea stagnalis and Helisoma trivolvis which is known to synapse upon specific visceral and parietal ganglion neurons in both species. Here we show that the giant dopamine cells can reform specific connections in vitro on follower neurons from both species. Thus the mechanisms that determine synapse specificity are conserved between two different families of molluscs.
我们测试了来自两种不同淡水腹足类软体动物的已鉴定神经元在体外形成特定连接的能力。本研究中选择的突触前神经元是椎实螺和三角帆蚌的巨大多巴胺能细胞，已知这两种动物的该神经元会与特定的内脏和壁神经节神经元形成突触。在这里我们表明，巨大多巴胺能细胞在体外可以与这两种动物的跟随神经元重新形成特定连接。因此，决定突触特异性的机制在两种不同的软体动物家族之间是保守的。
