This study aimed to answer the questions 'What are the neural networks and mechanisms involved in visual and kinesthetic motor imagery?', and 'Is part of cognitive processing included during visual and kinesthetic motor imagery?' by investigating the neurophysiological networks and activations during visual and kinesthetic motor imagery using motor imagery tasks (golf putting). The experiment was conducted with 19 healthy adults. Functional magnetic resonance imaging (fMRI) was used to examine neural activations and networks during visual and kinesthetic motor imagery using golf putting tasks. The findings of the analysis on cerebral activation patterns based on the two distinct types of motor imagery indicate that the posterior lobe, occipital lobe, and limbic lobe exhibited activation, and the right hemisphere was activated during the process of visual motor imagery. The activation of the temporal lobe and the parietal lobe were observed during the process of kinesthetic motor imagery. This study revealed that visual motor imagery elicited stronger activation in the right frontal lobe, whereas kinesthetic motor imagery resulted in greater activation in the left frontal lobe. It seems that kinesthetic motor imagery activates the primary somatosensory cortex (BA 2), the secondary somatosensory cortex (BA 5 and 7), and the temporal lobe areas and induces human sensibility. The present investigation evinced that the neural network and the regions of the brain that are activated exhibit variability contingent on the category of motor imagery.
本研究旨在通过使用运动想象任务（高尔夫推杆）来研究视觉和动觉运动想象过程中的神经生理网络及激活情况，从而回答“视觉和动觉运动想象涉及哪些神经网络和机制？”以及“视觉和动觉运动想象过程中是否包含部分认知加工？”这两个问题。该实验对19名健康成年人进行。使用功能磁共振成像（fMRI）通过高尔夫推杆任务来检测视觉和动觉运动想象过程中的神经激活及网络情况。基于两种不同类型运动想象对大脑激活模式的分析结果表明，后叶、枕叶和边缘叶出现激活，且在视觉运动想象过程中右半球被激活。在动觉运动想象过程中观察到颞叶和顶叶的激活。本研究表明，视觉运动想象在右额叶引发更强的激活，而动觉运动想象在左额叶导致更大的激活。似乎动觉运动想象激活了初级体感皮层（BA 2）、次级体感皮层（BA 5和7）以及颞叶区域并诱发人类的感觉。本研究表明，所激活的神经网络和脑区会因运动想象的类别不同而表现出变异性。
