知识处理的神经生物学理论偏向于语言主导（通常是左半球）。右半球对知识加工有重要作用吗？j。a。是一个左半球语言优势的个体他的右脑梭状回中部和前部受到了损伤。虽然她的语言能力完好无损，但她对生物和非生物实体的视觉属性有部分丧失。无论执行何种任务：对象识别、口头特征生成、强制选择命名定义或徒手绘图，都可以观察到这一点。功能联想和非视觉感官属性被保留。在对27名志愿者进行的功能性磁共振成像研究中，J.A.受损的同一区域也被激活了。这些志愿者检索了概念之间的语义关联，但前提是这些概念是以图片而不是文字的形式表示的。因此，右梭状回对熟悉实体的视觉属性的有意识回忆起重要作用。
Neurobiological theories of knowledge processing are biased toward the language-dominant (usually the left) hemisphere. Does the right hemisphere critically contribute to knowledge processing? J.A. is a left-hemisphere language-dominant individual who suffered a lesion confined to the right mid- and anterior fusiform gyrus. Although her language abilities are intact, she showed a partial loss of knowledge of the visual attributes of biological and nonbiological entities. This was observed regardless of the task performed: object discrimination, oral feature generation, forced-choice naming-to-definition or free-hand drawing. Functional-associative and nonvisual sensory attributes were spared. The same region that was lesioned in J.A. was activated in a functional magnetic resonance imaging study in 27 volunteers who retrieved semantic associations between concepts, but only if the concepts were represented as pictures and not as words. Therefore, right fusiform gyrus critically contributes to the conscious recollection of visual attributes of familiar entities.
