大量的神经影像学和神经心理学研究强调了腹侧、枕颞视觉处理流在表征和提取物体外观的语义记忆中的作用。在这里，我们研究的作用顶叶皮层在检索对象的形状信息。当受试者听到常见物体的名字并对其形状做出判断时，功能磁共振成像数据被采集。招募左下顶叶（IPL）在形状检索调制的量与对象相关的先前的触觉经验。此外，在右中央后回中观察到相同的活动模式，这表明对象形状的表示分布在与该属性的感觉运动获取历史相关的区域之间，正如分布式语义记忆模型所预测的那样。
Numerous neuroimaging and neuropsychological studies have highlighted the role of the ventral, occipitotemporal visual processing stream in the representation and retrieval of semantic memory for the appearance of objects. Here, we examine the role of the parietal cortex in retrieval of object shape information. fMRI data were acquired as subjects listened to the names of common objects and made judgments about their shape. Recruitment of the left inferior parietal lobule (IPL) during shape retrieval was modulated by the amount of prior tactile experience associated with the objects. In addition, the same pattern of activity was observed in right postcentral gyrus, suggesting that the representation of object shape is distributed amongst regions that are relevant to the sensorimotor acquisition history of this attribute, as predicted by distributed models of semantic memory.
