关于5- 11岁儿童腹侧处理流的正常功能组织和发育的信息很少。目前的fMRI研究确定了5-8岁和9-11岁儿童面部和物体处理的神经相关性，并使用类似的成人研究数据进行比较。所有年龄组的腹侧加工流中的面部优先激活，但成人和9-11岁的儿童在经典定义的梭状面区域附近显示面部优先位点，而5-8岁的儿童在后腹侧加工流中显示这种激活。此外，随着年龄的增长，其他大脑区域的类别选择性程度也在增加。总的来说，这些发展变化可能反映了基于学习和经验的视觉识别过程的微调。
Information on normal functional organization and development of the ventral processing stream in 5- to 11-year-old children is minimal. The present fMRI study identified neural correlates for face and object processing in children aged 5-8 and 9-11 years, with data from a similar adult study used for comparison. All age groups showed face-preferential activation in the ventral processing stream, but adults and children aged 9-11 years showed face-preferential loci near the classically defined fusiform face area, whereas children aged 5-8 years showed this activation in the posterior ventral processing stream. In addition, the degree of category-selectivity in other brain regions increased with age. Collectively, these developmental changes may reflect fine-tuning in visual recognition processes based on learning and experience.
