Functional magnetic resonance imaging in awake monkeys and humans was used to compare object adaptation in shape-sensitive regions of these two species under identical and different size conditions. Object adaptation was similar in humans and monkeys under both conditions. Neither species showed complete size invariance, in agreement with single-cell studies. Both the macaque inferotemporal (IT) complex and human lateral occipital complex (LOC) displayed an anteroposterior gradient in object adaptation and size invariance, with the more anterior regions being more adaptable and size invariant. The results provide additional evidence for the homology between the macaque IT cortex and human LOC but also add to the growing list of differences between human and monkey intraparietal sulcus regions.
利用清醒猴子和人类的功能磁共振成像,在相同和不同大小条件下比较这两个物种形状敏感区域的物体适应性。在这两种条件下,人类和猴子的物体适应性相似。与单细胞研究一致,两个物种均未表现出完全的大小不变性。猕猴颞下(IT)复合体和人类枕外侧复合体(LOC)在物体适应性和大小不变性方面均呈现前后梯度,前部区域更具适应性且大小不变。这些结果为猕猴IT皮层和人类LOC之间的同源性提供了额外证据,但也增加了人类和猴子顶内沟区域之间越来越多的差异。
