高级数学推理，无论领域或难度如何，都会激活一组可重复的双侧大脑区域，包括顶叶内、颞下和背侧前额叶皮层。然而，遗传学、经验和教育在这一数学反应网络的发展中各自的作用仍然没有得到解决。在这里，我们调查的视觉经验的作用，通过研究三个专业的数学家谁是盲人从出生（n = 1）或在儿童时期失明（n = 2）的例外情况。受试者在判断口头数学和非数学陈述的真值时接受功能磁共振成像扫描。盲人数学家在数学反思过程中激活了数学相关领域的经典网络，这与一组视力正常的专业数学家相似。因此，高级数学推理的大脑网络可以在没有视觉经验的情况下发展。在枕叶皮层中发现了额外的激活，即使在儿童时期失明的人中也是如此，这表明盲人数学家可能会出现心理意象或视觉皮层的更激进的重新用途。
Advanced mathematical reasoning, regardless of domain or difficulty, activates a reproducible set of bilateral brain areas including intraparietal, inferior temporal and dorsal prefrontal cortex. The respective roles of genetics, experience and education in the development of this math-responsive network, however, remain unresolved. Here, we investigate the role of visual experience by studying the exceptional case of three professional mathematicians who were blind from birth (n = 1) or became blind during childhood (n = 2). Subjects were scanned with fMRI while they judged the truth value of spoken mathematical and nonmathematical statements. Blind mathematicians activated the classical network of math-related areas during mathematical reflection, similar to that found in a group of sighted professional mathematicians. Thus, brain networks for advanced mathematical reasoning can develop in the absence of visual experience. Additional activations were found in occipital cortex, even in individuals who became blind during childhood, suggesting that either mental imagery or a more radical repurposing of visual cortex may occur in blind mathematicians.
