Researchers have found that small numbers are processed in the right side of the brain, while large numbers are processed in the left side of the brain, according to a study published Friday by Imperial College London.
The brain is divided into two halves, with the left side controlling the right half of the body, and vice versa. Previous studies have highlighted the general region where the brain handles numbers, an area called the fronto-parietal cortex. But scientists are in the dark about how exactly the brain unpicks and processes numbers.
