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.
这项皮质刺激映射研究调查了动作和物体命名的神经表征。呈现了13名接受清醒皮质映射的神经外科受试者的数据。我们的研究结果表明，在这个命名任务中，名词和动词命名的差异性破坏有明确证据。在个体层面，发现了颞叶周围皮质的点状区域存在负责名词和动词功能的证据。然而，在不同受试者之间，这些部位的位置有所不同。这一发现可能有助于解释名词和动词命名的病变研究与功能成像研究之间的差异。此外，对这些数据的另一种编码方式有助于突出目标反应的语法类别易损性。这种编码方案的使用表明缘上回在动词命名行为中发挥作用。我们将根据动词命名背后的功能 - 解剖学通路来讨论这些数据。
