The brain has specialized regions for processing numerical information from "summary" of The Number Sense by Stanislas Dehaene
The human brain exhibits remarkable specialization when it comes to handling numbers. Distinct regions are dedicated to various aspects of numerical processing, reflecting a sophisticated architecture that evolved to manage mathematical tasks. One of the primary areas implicated in numerical cognition is the intraparietal sulcus (IPS), which plays a crucial role in estimating quantities and understanding numerical magnitudes. This region integrates sensory inputs and translates them into a mental representation of numbers. Adjacent to the IPS lies the angular gyrus, which is involved in more complex numerical tasks, such as arithmetic and verbal numerical skills. This area is essential for the manipulation of numbers and the retrieval of numerical facts, linking the abstract world of numbers to language and memory. The left hemisphere is particularly engaged during these operations, suggesting a lateralization of function where language and arithmetic intertwine. The brain's processing of...
