材料与方法本研究采用4种不同电鱼（Eigenmannia virescens，Sternarchus albifrons，Sternopygus sp.，Hypopomus sp.）共42条，体长10 ~ 18 cm。一般的实验程序与以前的论文（12）中所述的类似。用甲磺酸三卡因（MS-222）（1份/150，000）麻醉鱼，另外，用0.03 mg. d-管箭毒碱鲜重与其他电鱼不同的是，箭毒不会减少或消除这种电鱼的电器官的放电。这是预料之中的，因为胸骨弓的电器官是一个改良的神经突（1）。箭毒的固定大大促进了微电极的记录。
MATERIALS AND METHODSThe present report is based on experiments on 42 specimens of four different electric fish species, Eigenmannia virescens, Sternarchus albifrons, Sternopygus sp. and Hypopomus sp. All specimens were IO-18 cm. long.The general experimental procedure was similar to that described in a previous paper (12). The fish was anesthetized with tricaine methanesulfonate(MS-222)(1 part per 150,000) and Sternarchus was, in addition, curarized with 0.03 mg. d-tubocurarinelg. fresh weight. Unlike other electric fish, the discharge of the electric organ of this species is not reduced or abolished by curare. This was expected as the electric organ in Sternarchus is a modified neurite (1). The immobilization by curare considerably facilitated recording with microelectrodes.
