左顶叶被认为是一个主要的语言区域。然而，顶叶皮质功能更通常被认为是在控制的行动，既有助于注意和外部和传入的感觉线索的跨模态整合。我们使用正电子发射断层扫描来研究正常受试者，同时他们公开地产生叙述，包括口头和书面的。其目的是确定顶叶的贡献，特定的模态的感觉运动控制的通信，独立于amodal的语言和记忆过程中参与产生的叙事。大多数的左，右顶叶活动与视觉和体感控制下的写作执行，无论输出是一个单一的字形的叙述或重复再现。与此相反，言语产生过程中与动作相关的顶叶活动仅限于初级躯体感觉皮层。顶叶区域的活动模式与交流中的非模式中枢作用相一致的唯一区域是左侧角回（AG）的腹侧部分。这项研究的结果表明，顶叶内的语言认知处理仅限于AG和顶叶皮层的主要贡献，以通信是在感觉运动控制的写作。
The left parietal lobe has been proposed as a major language area. However, parietal cortical function is more usually considered in terms of the control of actions, contributing both to attention and cross-modal integration of external and reafferent sensory cues. We used positron emission tomography to study normal subjects while they overtly generated narratives, both spoken and written. The purpose was to identify the parietal contribution to the modality-specific sensorimotor control of communication, separate from amodal linguistic and memory processes involved in generating a narrative. The majority of left and right parietal activity was associated with the execution of writing under visual and somatosensory control irrespective of whether the output was a narrative or repetitive reproduction of a single grapheme. In contrast, action-related parietal activity during speech production was confined to primary somatosensory cortex. The only parietal area with a pattern of activity compatible with an amodal central role in communication was the ventral part of the left angular gyrus (AG). The results of this study indicate that the cognitive processing of language within the parietal lobe is confined to the AG and that the major contribution of parietal cortex to communication is in the sensorimotor control of writing.
