Two types of operation have been made on the nervous system of Unio pectorum: 1) one cerebral ganglion was removed, whereas the remaining ganglion was deprived of all connections except the cerebro-pedal one; 2) both cerebral ganglia were removed. The evoked activity induced by chemical stimulation of the mantle was recorded in the visceral ganglion. After the first type of operation the amplitude of the EP decreases, whereas after the second one increases. Electrical stimulation of the cerebral and pedal ganglia immediately after decerebralization decreases the evoked activity. Stimulation of the pedal ganglion increases the amplitude of the evoked potentials 2--6 days after the removal of both cerebral ganglia. The existence of cerebro-pedal-visceral connection is suggested and neuronal relationships in the system of these connections are discussed.
1）切除一个脑神经节，而其余神经节除脑足神经连接外的所有连接均被切断；2）切除两个脑神经节。在内脏神经节中记录了外套膜化学刺激诱发的活动。第一种手术后，诱发电位（EP）的幅度降低，而第二种手术后则增加。去脑后立即对脑和足神经节进行电刺激会降低诱发活动。切除两个脑神经节后2 - 6天，刺激足神经节会增加诱发电位的幅度。文中提出了脑 - 足 - 内脏连接的存在，并讨论了这些连接系统中的神经元关系。
