area 9M - BrainInfo

area 9M (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 ).

Also known as: area 9M, area 9M of cortex, medial part, area 9m, area 9 middle

Models Where It Appears

Topographic Model of Human Cerebral Cortex

The topographic model of human cerebral cortex is a closed partitive hierarchical model of cerebral cortical structure in the human. The cerebral cortex is segmented on the basis of internal structure, connectivity, and/or functions of cortical areas. It is designed to update the comprehensive early twentieth century parcellations of Brodmann and of von Economo and Koskinas and their successors. A work in progress, it integrates the most authoritative, comprehensive, and recent parcellations and nomenclatures from peer-reviewed publications and neuroanatomical texts. For an equivalent model in the rodent, Search BrainInfo for ' Functional CNS Model - Rat '. This segmentation of the human cerebral cortex, based on a combination of internal structure, connectivity, and function, complements the classical segmentation of the cerebral cortex into lobes, lobules, and gyri based on sulcal patterns: For the classical segmentation, see ' cerebral cortex ' and click 'Locus in Brain Hierarchy'.
