A moon near to the horizon is perceived larger than a moon at the zenith, although--obviously--the moon does not change its size. In this study, the neural mechanisms underlying the "moon illusion" were investigated using a virtual 3-D environment and fMRI. Illusory perception of an increased moon size was associated with increased neural activity in ventral visual pathway areas including the lingual and fusiform gyri. The functional role of these areas was further explored in a second experiment. Left V3v was found to be involved in integrating retinal size and distance information, thus indicating that the brain regions that dynamically integrate retinal size and distance play a key role in generating the moon illusion.
尽管地平线附近的月亮看起来比天顶处的月亮大（显然，月亮的大小并没有改变）。在本研究中，利用虚拟三维环境和功能磁共振成像技术研究了“月亮错觉”背后的神经机制。对月亮大小增加的错觉感知与包括舌回和梭状回在内的腹侧视觉通路区域神经活动增加有关。在第二个实验中进一步探究了这些区域的功能作用。发现左侧V3v参与整合视网膜大小和距离信息，因此表明动态整合视网膜大小和距离的脑区在产生月亮错觉中起关键作用。
