人类和非人类灵长类动物的物体视觉经常被认为是成人神经信息处理可塑性的主要例子。据推测,视觉体验导致猴脑中的单个神经元对复杂物体具有很强的选择性,而人脑中的区域则对特定类别的高度熟悉的物体具有强烈的选择性。这种观点表明,成人视觉体验会导致高级视觉皮层的反应特性发生巨大的局部变化。在这里,我们回顾了当前的神经生理学和神经影像学证据,发现现有数据支持不同的结论:成人视觉体验引入了适度的、相对分布的效应,调节预先存在的、丰富且灵活的神经对象表征集。
Object vision in human and nonhuman primates is often cited as a primary example of adult plasticity in neural information processing. It has been hypothesized that visual experience leads to single neurons in the monkey brain with strong selectivity for complex objects, and to regions in the human brain with a preference for particular categories of highly familiar objects. This view suggests that adult visual experience causes dramatic local changes in the response properties of high-level visual cortex. Here, we review the current neurophysiological and neuroimaging evidence and find that the available data support a different conclusion: adult visual experience introduces moderate, relatively distributed effects that modulate a pre-existing, rich and flexible set of neural object representations.
