title: Thinking big; many modules or much cortex?
abstract: Is there a neural system dedicated to generic magnitude judgments? In this issue of Neuron, Pinel et al. report qualitative spatial overlap of fMRI responses during judgments of luminance, size, and numerical magnitude but also quantitative response differences in intraparietal cortex that mirror behavioral interference between perceptual and symbolic magnitude.
