在视野受限部分处理信息的感受野 (RF) 是视觉系统神经元的关键属性。然而,RFs 在人类中如何发展尚不清楚。使用功能磁共振成像和儿童和成人的群体感受野 (pRF) 模型,我们确定 pRF 在腹侧视觉流中的发育位置和方式。在这里,我们报告说,视野图中的 pRF 属性,从第一视觉区域 V1 到第一腹枕区 VO1,在 5 岁时与成人相似。然而,面部选择性和字符选择性区域的 pRF 属性发展到成年,增加了右半球面部和左半球单词的中心凹覆盖偏差。眼动追踪表明,pRF 的变化与发育过程中对单词和面孔的注视模式的变化有关。这些发现表明面部和文字观看行为与整个视觉皮层 pRF 的差异发展之间存在联系,这可能是由于中央凹覆盖范围的竞争所致。视觉系统中的群体感受野(pRF)是关键的信息处理器,但它们如何发展尚不清楚。在这里,作者在儿童和成人中使用功能磁共振成像和 pRF 模型来表明,在腹侧流中,只有面部和单词选择性区域的 pRF 继续发展,反映了观看行为的变化。
Receptive fields (RFs) processing information in restricted parts of the visual field are a key property of visual system neurons. However, how RFs develop in humans is unknown. Using fMRI and population receptive field (pRF) modeling in children and adults, we determine where and how pRFs develop across the ventral visual stream. Here we report that pRF properties in visual field maps, from the first visual area, V1, through the first ventro-occipital area, VO1, are adult-like by age 5. However, pRF properties in face-selective and character-selective regions develop into adulthood, increasing the foveal coverage bias for faces in the right hemisphere and words in the left hemisphere. Eye-tracking indicates that pRF changes are related to changing fixation patterns on words and faces across development. These findings suggest a link between face and word viewing behavior and the differential development of pRFs across visual cortex, potentially due to competition on foveal coverage. Population receptive fields (pRFs) in the visual system are key information-processors, but how they develop is unknown. Here, authors use fMRI and pRF modeling in children and adults to show that in the ventral stream only pRFs in face- and word-selective regions continue to develop, mirroring changes in viewing behavior.
