"....post-infant humans are unique in possessing precise mathematical cognition. Historically, what is known as the Triple Code model of numeric processing has
hypothesized that symbolic, verbal, and abstract processing – for example, simple visual recognition of a numeral, determining the larger of two numerals, and verbal naming of a numeral, respectively – occur in well-defined coupled brain regions, all or some of which interact. Recently, however, scientists employing electrocorticography (ECoG) electrophysiological recording – in which electrodes are placed directly on the exposed surface of the brain's cerebral cortex – not only reconfirmed math-selective hubs within the lateral parietal cortex (LPC) and ventral temporal cortex (VTC), but more significantly found what they describe as a remarkable diversity of neural responses within each region at both millimeter and millisecond scales.
The study's results suggested the presence of what appears to be a temporally- and functionally-synchronized and anatomically selective numerical cognition system. "Just as language processing is associated with a brain network engaged during different aspects of language – for example, visual, semantic and phonetic components –
we've identified a brain network for numerical cognition which appears to be involved in processes such as the visual recognition of numerals and arithmetic computations." Daitch explains. She notes that the posterior inferior temporal gyrus (pITG) region of the VTC, which is selective to numerical/mathematical processing, is anatomically distinct from other VTC regions that may be selective for the processing of letters and words, and moreover exhibited anatomically selective functional coupling – during both mathematical tasks and at rest – with an area of the parietal lobe associated with processing quantity.
...heterogeneous subpopulations within the VTC and LPC appeared to be engaged in distinct bidirectional loops between these regions during different stages of arithmetic computations."
