动物王国中有各种各样的感觉系统，它们被选择在不同的环境中发挥作用，但在生物体的一生中，它们也会受到经验的修改。通过经验对这种系统的修改通常被称为感知学习。在啮齿动物中，感知学习的经典例子是观察到简单的预先暴露于两种视觉刺激有助于随后（强化）区分它们。然而，直到最近，很少有行为研究调查触觉刺激下啮齿动物的感知学习，这与关于啮齿动物体感系统可塑性的丰富信息形成鲜明对比。在这里，我们有选择性地回顾了触觉刺激下感知学习的行为分析，以及有关体感系统中这种影响的潜在基础的证据。
The animal kingdom contains species with a wide variety of sensory systems that have been selected to function in different environmental niches, but that are also subject to modification by experience during an organism’s lifetime. The modification of such systems by experience is often called perceptual learning. In rodents, the classic example of perceptual learning is the observation that simple preexposure to two visual stimuli facilitates a subsequent (reinforced) discrimination between them. However, until recently very little behavioral research had investigated perceptual learning with tactile stimuli in rodents, in marked contrast to the wealth of information about plasticity in the rodent somatosensory system. Here we present a selective review of behavioral analyses of perceptual learning with tactile stimuli, alongside evidence concerning the potential bases of such effects within the somatosensory system.
