The term area 8BM refers to the more caudal of two parts of dorsomedial prefrontal cortex in the human ( Bzdok-2011 ). The other is area 9m. Located on the medial surface of the superior frontal gyrus, it is a spindle-shaped area bounded dorsally by dorsolateral prefrontal cortex: area SFL, area 8BL and area 9m, and ventrally by anterior cingulate cortex: area SCEF, area a32pr, and area d32. Defined in the human by multiple criteria, it is fMRI-activated in MOTOR CUE, WORKING MEMORY, MATH, LANGUAGE MATH, and RELATIONAL tasks. It is deactivated in a THEORY OF MIND task. Other authors have referred to an overlapping part of the same topological area as 8B ( Glasser-2016 ).
