cuneus

Brain stem midbrain, borderline of medulla oblongata and pons cerebelli, right cuneus ( Brodmann area 18) and left cerebellum show hypermetabolism state of glucose ( p < 0.01).

脑干中脑、延桥交界、右侧楔叶（BA18）、左侧小脑表现为葡萄糖高代谢状态（P<0.01）。

The brain areas activated in the senior group during the mental abacus calculation were fewer and mainly localized in occipital lobe ( cuneus and infracalcarine gyrus) and parietal lobe ( precuneus and inferior parietal lobule).

高级组儿童珠心算时激活的脑区少且集中，主要位于枕叶（楔叶及舌回）及顶叶（楔前叶及顶下小叶）。

Occipital lobe ( bilateral cuneus) and parietal lobe ( precuneus and inferior parietal lobule) were activated in both groups during addition and subtraction tasks; and occipital cortex and parietal cortex were also activated in the three calculation tasks with different difficulty levels.

两组被试儿童在不同的运算任务中几乎均可见枕叶（双侧楔叶）及顶叶（楔前叶、顶下小叶）激活；不同难度的加法运算中亦可见顶、枕皮质的激活。
