本研究探讨了动作和物体命名的神经表征。数据来自13名神经外科受试者进行清醒皮层映射。我们的研究结果表明，在这个命名任务的背景下，名词和动词命名的差异中断的明确证据。在个体水平上，我们发现大脑外侧裂周皮层的标点区域对名词和动词功能起作用。然而，在不同的受试者中，这些部位的位置各不相同。这一发现可能有助于解释名词和动词命名的病变和功能成像研究之间的差异。此外，这些数据的另一种编码用于突出目标响应的语法类别脆弱性。这种编码方式的使用暗示了边缘上回在动词命名行为中的作用。这些数据进行了讨论相对于一个功能解剖路径动词命名。(C)2004 Wiley-Liss，Inc.
This cortical stimulation mapping study investigates the neural representation of action and object naming. Data from 13 neurosurgical subjects undergoing awake cortical mapping is presented. Our findings indicate clear evidence of differential disruption of noun and verb naming in the context of this naming task. At the individual level, evidence was found for punctuate regions of perisylvian cortex subserving noun and verb function. Across subjects, however, the location of these sites varied. This finding may help explain discrepancies between lesion and functional imaging studies of noun and verb naming. In addition, an alternative coding of these data served to highlight the grammatical class vulnerability of the target response. The use of this coding scheme implicates a role for the supramarginal gyrus in verb-naming behavior. These data are discussed with respect to a functional-anatomical pathway underlying verb naming.
