在这项研究中，我们测量了初级视觉皮层和额叶语言区的激活模式，并比较了自发思维过程中大脑视觉化信息能力强和弱的个体。受试者首先被管理的5项问卷，以评估他们的能力，创造心理图片，并在此基础上分为两组（强和弱的视觉）。然后，他们执行需要视觉图像和言语回忆的任务，并使用脑磁图（MEG）测量他们的局部神经活动。值得注意的是，在高β波段（25 Hz），视觉区（BA 17）在强视觉者中被更强烈地激活，而额叶语言区在弱视觉者中被更强烈地激活。强的视觉化者被认为是视觉思考者，弱的视觉化者被认为是语言思考者。
In this study we measured activation patterns in the primary visual cortex and the frontal language areas and compared them in individuals with strong and weak capacities to mentally visualize information during spontaneous thinking. Subjects were first administered a 5-item questionnaire to assess their ability to create mental pictures, and were divided into two groups (strong and weak visualizers) on this basis. They then performed tasks requiring visual imagery and verbal recollection, and their local neural activities were measured, using magnetoencephalography (MEG). Notably in the high beta-band (25 Hz), the visual area (BA 17) was more strongly activated in strong visualizers, whereas, the frontal language areas were more strongly activated in weak visualizers. Strong visualizers are considered to be visual thinkers, and weak visualizers are verbal thinkers.
