The functional magnetic resonance (fMRI) technique can be robustly used to map functional activation of the visual pathway including the primary visual cortex (V1), the lateral geniculate nucleus (LGN), and other nuclei of humans during visual perception stimulation. One of the major controversies in visual neuroscience is whether lower-order visual areas involve the visual imagery process. This issue was examined using fMRI at high magnetic field. It was demonstrated for the first time that the LGN was activated during visual imagery process in the human brain together with V1 and other activation. There was a tight coupling of the activation between V1 and the LGN during visual imagery.
功能磁共振成像（fMRI）技术可被可靠地用于绘制视觉通路的功能激活情况，包括人类在视觉感知刺激过程中的初级视觉皮层（V1）、外侧膝状体核（LGN）以及其他核团。视觉神经科学中的一个主要争议是较低级别的视觉区域是否参与视觉意象过程。本研究使用高磁场fMRI对此问题进行了探讨。首次证明，在人类大脑的视觉意象过程中，LGN与V1及其他区域一同被激活。在视觉意象过程中，V1和LGN之间的激活存在紧密耦合。
