area 9M
Acronym: 9M
The term area 9M refers to the more rostral of two parts of dorsomedial prefrontal cortex located on the medial surface of the superior frontal gyrus in the human ( Bzdok-2012 ) and the macaque ( Petrides-2009 ). The other is area 8BM, which lies caudoventral to it. It is bounded dorsolaterally by area 9p and area 9a of dorsolateral prefrontal cortex, rostrally by area 10d of polar frontal cortex, and posteriorly by area d32 and area a24 of anterior cingulate cortex. Defined in the human by multiple criteria, it is fMRI-activated in a THEORY OF MIND task. It is deactivated in a RELATIONAL task, and activated or deactivated in a LANGUAGE task depending on the task with which it is compared. Other authors have referred to an overlapping part of another structure in the same topological area as 9 ( Glasser-2016 ).
