Abstract
Is there a common neural code underlying the representation of different quantity dimensions? In a high resolution fMRI protocol, we compared the activation evoked by the presentation of lines with different lengths, and sets of different numbers. We contrasted the results obtained with standard univariate analyses with a multivariate approach comparing the representational similarities within and between dimensions (i.e. few : short = many : long?). Together, our findings suggest that although the representations of number and size are co-localized in parietal cortex, these two quantity dimensions do not share a common representational code.
