Abstract: Processing Magnitudes within the Parietal Cortex

Human beings constantly process number/numerosity, space and duration to regulate and adapt their behaviour to the external world. It has been suggested that these adaptive abilities rely on a common magnitude processing system hosted by the parietal cortex. In this talk, I will review the recent behavioural, lesional and brain imaging studies from my research group demonstrating functional interactions as well as the cerebral bases underlying magnitude processing in human adults. Similarities and differences between numerical, temporal and spatial processing will be detailed to show the links between different magnitude estimation processes, as revealed by the behavioural interactions observed during multiple dimensions processing. I will (try to) make it clear that areas around the left and right intraparietal sulci host both common and partially distinct and specific representations and mechanisms for number/numerosity, space and duration processing, and I will show how these areas interact with frontal areas to achieve these functions.
