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.
在人类和非人类灵长类动物中，物体视觉通常被认为是神经信息处理中成年期可塑性的主要范例。人们假设，视觉经验导致猴子大脑中的单个神经元对复杂物体具有强烈的选择性，并且导致人类大脑中对特定类别高度熟悉的物体具有偏好的区域。这种观点表明，成年视觉经验会导致高级视觉皮层的反应特性发生剧烈的局部变化。在这里，我们回顾了当前的神经生理学和神经影像学证据，发现可用数据支持了一个不同的结论：成年视觉经验引入了适度的、相对分布的影响，这些影响调节了预先存在的、丰富而灵活的一组神经物体表示。
