人类视觉区域V1，V2，VP，V3和V4的边界是精确且无创的。在相位编码的视网膜刺激期间记录了功能磁共振图像。然后用皮质表面重建对此体积数据集进行采样，从而可以计算局部视野标志（镜像与非MIRROR图像表示）。此方法自动且客观地概述了区域边界，因为相邻区域通常具有相反的场符号。确定了枝条和腹腔外皮质区域的皮质放大因子曲线，这表明人类视觉区域比在猴子中的同行更加重视凝视中心。人类的视网膜组织视觉区域向前延伸，以重叠以前显示的几个区域，这些区域被书面单词激活。
The borders of human visual areas V1, V2, VP, V3, and V4 were precisely and noninvasively determined. Functional magnetic resonance images were recorded during phase-encoded retinal stimulation. This volume data set was then sampled with a cortical surface reconstruction, making it possible to calculate the local visual field sign (mirror image Versus non-mirror image representation). This method automatically and objectively outlines area borders because adjacent areas often have the opposite field sign. Cortical magnification factor curves for striate and extrastriate cortical areas were determined, which showed that human visual areas have a greater emphasis on the center-of-gaze than their counterparts in monkeys. Retinotopically organized visual areas in humans extend anteriorly to overlap several areas previously shown to be activated by written words.
