功能磁共振成像（fMRI）用于识别和绘制人类大脑皮层七个区域的视野表现，并识别至少两个额外的视觉响应区域。在皮层的三维模型和皮层表面的展开图上绘制了沿垂直或水平视野经络响应刺激的神经元的皮层位置，这些图用于识别与猕猴V1， V2, V3， VP区域以及部分V3A和V4区域在地形上同源的区域之间的边界。我们还观察到与中颞叶/内侧颞上区复区同源的视觉响应区和未识别的顶叶视觉区。迄今为止所识别的视觉区域的地形与猕猴的组织一致。然而，这些和其他研究结果表明，人类和猿猴的皮层组织可能在V3A和V4或以上的纹外皮层开始出现差异。
Functional magnetic resonance imaging (fMRI) was used to identify and map the representation of the visual field in seven areas of human cerebral cortex and to identify at least two additional visually responsive regions. The cortical locations of neurons responding to stimulation along the vertical or horizontal visual field meridia were charted on three-dimensional models of the cortex and on unfolded maps of the cortical surface, These maps were used to identify the borders among areas that would be topographically homologous to areas V1, V2, V3, VP, and parts of V3A and V4 of the macaque monkey, Visually responsive areas homologous to the middle temporal/medial superior temporal area complex and unidentified parietal visual areas were also observed, The topography of the visual areas identified thus far is consistent with the organization in macaque monkeys, However, these and other findings suggest that human and simian cortical organization may begin to differ in extrastriate cortex at, or beyond, V3A and V4.
