We understand quite well now what are the cortical areas involved, and the neural codes for individual quantities as perceptual entities. Still, we lack a general understanding of how quantity representations are transformed during mental computations, and how or even where results of such computations are coded in the brain. By using ultra-high-field (UHF) imaging during an approximate calculation task designed to disentangle in- and outputs of a computation from the operation, we uncovered a representation of internally generated quantities which was most prominent in higher-level regions like the angular gyrus and lateral prefrontal cortex, and the intra-parietal sulcus. Intraparietal sensory-motor integration regions were the only ones found to share the same representational space for stimulus-evoked and internally generated quantities. This suggests the transformation may occur in these regions, before result numbers are maintained for task purposes in higher-level areas in a format possibly detached from sensory-evoked inputs. Results illustrate the power of UHF imaging to finely characterize neural codes underlying human numerical abilities with non-invasive methods.
