[A]. High-level mathematical expertise and basic number sense share common roots in a non-linguistic brain circuit.
[B]. Regardless of domain- algebra, analysis,geometry or topology- mathematicians recognize and manipulate numbers mentally.
[C]. Classic left-hemisphere regions involved in verbal semantics are not as well developed in mathematicians as the brain areas involving number and space.
[D]. The mathematical achievement of an individual can be predicted based on his knowledge of number, space and language during childhood.

A recent study, published in the Proceedings of the National Academy of Sciences, has shown that high-level mathematical reasoning rests on a set of brain areas that do not overlap with the classical left-hemisphere regions involved in verbal semantics. Click here to read full transcript
Instead, all domains of mathematics tested recruit a bilateral network, of prefrontal, parietal, and inferior temporal regions, which is also activated when mathematicians or non-mathematicians recognize and manipulate numbers mentally. These results suggest that high-level mathematical thinking makes minimal use of language areas and instead recruits circuits initially involved in space and number. This result may explain why knowledge of number and space, during early childhood, predicts mathematical achievement.
