Abstract
Based on neuroimaging methods it is a commonly held view that numerical representation in the human parietal lobes is format-independent. We used a transcranial magnetic stimulation adaptation paradigm to examine the existence of functionally segregated overlapping populations of neurons for different numerical formats, and to reveal how numerical information is encoded and represented. Based on two experiments we found that right parietal lobe stimulation showed a dissociation between digits and verbal numbers, while the left parietal lobe showed a double dissociation between the different numerical formats. Further analysis and modelling also excluded pre- or post-representational components as the source of the current effects. These results demonstrate that both parietal lobes are equipped with format-dependent neurons that encode quantity.
