Goldfish Carassius auratus were presented with a moving shadow stimulus at 2-min intervals and their cardiac and ventilatory responses were monitored. Normal fish, fish with their telencephalon ablated, and those with sham operations were compared for responsiveness and habituation to repeatedly presented stimuli over the 3-day test period. While all groups showed increased habituation on successive days testing, fish with their telencephalon ablated showed significantly slower response habituation within the daily test sessions when compared with the control groups. Subjects with their telencephalon ablated also showed a tendency for increased responsiveness on initial stimulus presentation and poorer retention between days of information relating to the eliciting test stimulus.
每隔2分钟给金鱼(Carassius auratus)呈现一次移动的阴影刺激,并监测它们的心脏和呼吸反应。在为期3天的测试期内,比较了正常鱼、端脑被切除的鱼和接受假手术的鱼对反复呈现的刺激的反应性和适应性。虽然所有组在连续几天的测试中适应性都有所增强,但与对照组相比,端脑被切除的鱼在每日测试过程中的反应适应性明显较慢。端脑被切除的实验对象在最初呈现刺激时也表现出反应性增强的趋势,并且在与引发测试刺激相关的信息的不同日期之间的记忆保持较差。
