Passive nonverbal numerical adaptation paradigm (bottom row) and brain-activation findings for adults (left), 4-year-old children (middle), and infants (right). All three age groups show changes in brain activation in or near the intraparietal sulcus (green arrows) when an infrequent numerical stimulus (bottom, third frame from right) deviates from the frequently presented numerosity. Left brain image reproduced from “Tuning Curves for Approximate Numerosity in the Human Intraparietal Sulcus,” by M. Piazza, V. Izard, P. Pinel, D. Le Bihan, & S. Dehaene, 2004, Neuron, 44, 547–555.
