| 摘 要： | 在7尾鲶鱼所记录到的11个电感觉中枢神经元中,6个只对运动的偶极子电场有反应;4个对运动和静止的偶极子电场均有反应,但以前者反应最强;另一个神经元不仅对运动的偶极子电场,而且对运动的塑料棒也有反应。研究表明,鲶鱼的电感应中枢最适合于察觉移动的电场目标。

| Abstract: | The work is aimed to explore response properties of neurons to stationary ormoving dipoles in electroreceptive centers of catfish.Eleven neurons from 7 fishwere recorded from the lobus caudalis pars lateralis and nucleus praeeminen-tialis.Six of them were sensitive only to moving dipole,four to both moving andstationary dipoles,only one to moving dipole and moving plastic rod.Theseobservations indicate that the electroreceptive central neurons in catfish are es-sentially involved in detecting moving electric objects. |
