使用激活似然估计(ALE)元分析，我们确定了当人们命名动物图片和工具图片时所调用的大脑区域。我们发现，给动物命名和命名工具调用了大脑中独立的分布式网络。具体地说，我们发现，在额叶结构中，命名动物比命名工具引起的反应更大，额叶结构通常受情绪内容和任务要求的调节，在腹侧流的许多视觉区域也是如此。相比之下，与命名动物相比，命名工具在腹侧流的一组不同区域引发了更大的反应。与给额叶运动区和顶叶感觉区的动物命名相比，命名工具也能激发更大的反应。我们在命名这两类物体时发现的唯一重叠的激活部位是在左侧三角部、左侧颞叶下回和左侧海马旁回。综上所述，我们的元分析显示，动物和工具被明确地呈现在视觉区域，但在通常被认为参与记忆和/或语义加工的区域中，动物和工具在颞叶和额叶的更高级别的关联区表现出趋同。我们的结果还表明，命名工具不仅涉及腹侧流中的可视区域，而且还涉及与工具使用相关的额顶网络。这个与工具使用有关的网络是否直接有助于识别，还需要进一步调查。(C)2009爱思唯尔有限公司。保留所有权利。
Using activation-likelihood estimation (ALE) meta-analysis, we identified brain areas that are invoked when people name pictures of animals and pictures of tools. We found that naming animals and naming tools invoked separate distributed networks in the brain. Specifically, we found that naming animals invoked greater responses than naming tools in frontal lobe structures that are typically modulated by emotional content and task demands, and in a number of visual areas in the ventral stream. In contrast, naming tools invoked greater responses in a different set of areas in the ventral stream than those invoked by naming animals. Naming tools also invoked greater responses than naming animals in motor areas in the frontal lobe as well as in sensory areas in the parietal lobe. The only overlapping sites of activation that we found for naming these two categories of objects were in the left pars triangularis, the left inferior temporal gyrus, and the left parahippocampal gyrus. Taken together, our meta-analysis reveals that animals and tools are categorically represented in visual areas but show convergence in higher-order associative areas in the temporal and frontal lobes in regions that are typically regarded as being involved in memory and/or semantic processing. Our results also reveal that naming tools not only engages visual areas in the ventral stream but also a fronto-parietal network associated with tool use. Whether or not this network associated with tool use contributes directly to recognition will require further investigation. (C) 2009 Elsevier Ltd. All rights reserved.
