English: (A) Typical distribution of Brodmann’s areas 39, 40, and 43 (Brodmann, 1909). BA 40 constitutes the supramarginal gyrus, which caps the fissure between B and S. A minimal region that encloses BA 40 may be defined by the Sylvian fissure, and lines that connect the end of scp with S and the latter with the end of an unnamed sulcus that extends caudally from B. (B) These landmarks are available in Einstein’s left hemisphere and enclose an area that probably approximates a minimal surface representation of BA 40. A supramarginal gyrus containing BA 40 did not cap ascending limb of the posterior Sylvian fissure, however, because the latter was continuous with postcentral inferior.
