Mathematics relies on an ancient brain network located in the parietal regions at the top and center of the brain’s outer folded cortex. That network helps us process space, time and numbers. Past studies on neurocognition in mathematics have focused on brain activity while considering problems that take a few seconds to solve. These studies have helped illuminate brain activity that supports focused attention and a special form of recall called working memory, which helps people keep numbers and other details top of mind in the short term.
