工具的使用与三种视觉流相关：背-背、腹-背和腹侧视觉流。这些流分别涉及处理在线运动规划、动作语义和工具语义特征。关于大脑如何代表虚拟工具，我们知之甚少。为了直接评估这个问题，创建了一个虚拟工具范例，该范例提供了在彼此隔离的情况下操纵工具组件的能力。在功能性磁共振成像（fMRI），成年参与者进行了一系列的虚拟工具操作任务中，视觉和运动运动学的工具进行了操纵。反应时间和手的运动方向进行监测，而任务的执行。功能成像显示，所有三个视觉流中的活动都存在，与物理工具使用的预期模式相似。然而，一个以前未报道的右半球活动网络被发现，包括右顶下小叶，中，上级颞回和缘上回-众所周知，该地区与左半球的工具处理。这些结果提供的证据表明，虚拟和物理工具是在相同的大脑区域内处理，虽然虚拟工具招募双边工具处理区域在更大程度上比物理工具。
Tool use is associated with three visual streams—dorso-dorsal, ventro-dorsal, and ventral visual streams. These streams are involved in processing online motor planning, action semantics, and tool semantics features, respectively. Little is known about the way in which the brain represents virtual tools. To directly assess this question, a virtual tool paradigm was created that provided the ability to manipulate tool components in isolation of one another. During functional magnetic resonance imaging (fMRI), adult participants performed a series of virtual tool manipulation tasks in which vision and movement kinematics of the tool were manipulated. Reaction time and hand movement direction were monitored while the tasks were performed. Functional imaging revealed that activity within all three visual streams was present, in a similar pattern to what would be expected with physical tool use. However, a previously unreported network of right-hemisphere activity was found including right inferior parietal lobule, middle and superior temporal gyri and supramarginal gyrus – regions well known to be associated with tool processing within the left hemisphere. These results provide evidence that both virtual and physical tools are processed within the same brain regions, though virtual tools recruit bilateral tool processing regions to a greater extent than physical tools.
