The study, conducted by researchers Simon Jacob, MD, and Andreas Nieder, PhD, at the University of TE-bingen in Germany, has shown that cells in the intraparietal sulcus (IPS) and the prefrontal cortex - brain regions important for processing whole numbers - are tuned to respond to particular fractions.
Previous research had shown that an innate sense of numbers is entirely controlled by a non-verbal region of the brain called the intraparietal sulcus.
Also activated were mesial premotor regions and bilateral superior posterior parietal cortex along the intraparietal sulcus.
