Research on the mental rotation task has sparked debate regarding the specific processes that underly the capability of humans to mentally rotate objects. The spread of reported brain activations suggests that mental rotation is subserved by a neural network circle. However, no common network has yet been found that uncovers the crucial processes underlying this ability. We aimed to identify the common network crucial for mental rotation by coordinate-based network mapping of previous neuroimaging findings in mental rotation. A meta-analysis revealed 710 peak activation coordinates from 42 fMRI studies in mental rotation, which include a total 844 participants. The coordinates were mapped to a normative functional connectome (n = 1000) to identify a network of connected regions. To account for experimental factors, we examined this network against two control tasks, action imitation and symbolic number processing. A common and crucial network for mental rotation, centring on dorsal premotor, superior parietal and inferior temporal lobes was revealed. This network, separated from other experimental aspects, suggests that the crucial processes underlying mental rotation are motor rotation, visuospatial processing, and higher order visual object recognition.
对心理旋转任务的研究引发了关于人类进行心理旋转能力的具体过程的争论。报道的大脑激活的传播表明，心理旋转由一个神经网络圆圈来支持。然而，尚未找到一个共同的网络来揭示这种能力的关键过程。我们旨在通过心理旋转的先前神经影像学研究的基于坐标的网络映射来确定对心理旋转至关重要的共同网络。元分析从心理旋转的 42 项 fMRI 研究中揭示了 710 个峰值激活坐标，其中包括 844 名参与者。将坐标映射到规范的功能连接体（n=1000）中，以确定连接区域的网络。为了考虑实验因素，我们针对两个对照任务，动作模仿和符号数字处理，检查了这个网络。揭示了一个共同的、对心理旋转至关重要的网络，其中心是背侧运动前区、顶叶上回和颞下回。这个与其他实验方面分离的网络表明，心理旋转的关键过程是运动旋转、视空间处理和更高阶的视觉物体识别。
