Abstract

We demonstrated a sensory preconditioning in the pond snail, Lymnaea stagnalis. An appetitive sucrose solution (a conditioned stimulus: CS1) and weak vibration (another conditioned stimulus: CS2) were first associated, and then the CS2 and an aversive KCl solution (an unconditioned stimulus: UCS) were done. To build the conditioning, two different training procedures, spaced and massed, were examined. After the both training, the sensory preconditioning was built: significantly fewer feeding response to the CS1 became elicited; slower latency to the first bite to the CS1 was induced. No significant differences on the memory retention between these training procedures were found in the sensory preconditioning.

摘要

我们在椎实螺（Lymnaea stagnalis）中证明了一种感觉预适应。首先将一种适口的蔗糖溶液（一种条件刺激：CS1）与微弱振动（另一种条件刺激：CS2）建立联系，然后将CS2与一种厌恶性氯化钾溶液（一种非条件刺激：UCS）进行关联。为了建立条件作用，研究了两种不同的训练程序，即间隔训练和集中训练。在两种训练之后，感觉预适应均得以建立：对CS1引发的摄食反应显著减少；对CS1首次咬食的潜伏期延长。在感觉预适应中，未发现这些训练程序在记忆保持方面存在显著差异。
