In a recent study by Cantlon and colleagues published in the latest Journal of Cognitive Neuroscience, they decided to measure the brain activity of 6-7 year-old children during numerical comparison tasks using fMRI

''…participants were required to compare a single digit Arabic number presented on the center square with the standard, 5. Participants were asked to reach and touch one of three squares on the screen with their index finger while their hand movement trajectories were recorded: the left square for 14, the center for 5, and the right for 69 (Song & Nakayama, 2007).
