Between childhood and adulthood, neural map of the brain rearranges to conceptualize arithmetic
WASHINGTON — It takes years for children to master the ins and outs of arithmetic. New research indicates that this learning process triggers a large-scale reorganization of brain processes involved in understanding written symbols for various quantities.
The findings support the idea that humans' ability to match specific quantities with number symbols, a skill required for doing arithmetic, builds on a brain system that is used for estimating approximate quantities. That brain system is seen in many nonhuman animals.
