In this talk, I will present a series of studies investigating the encoding of elementary math, as well as the architecture, spatiotemporal dynamics, and causal role of the underlying brain networks. I will show that arithmetic computations selectively activate a distinct network in the human brain, which dissociates from language areas and overlaps with regions related to object recognition, visuospatial attention, working memory and relational reasoning. Next, using machine le
