main olfactory bulb
Acronym: MOB
The term main olfactory bulb refers to an area defined by internal structure and located centrally in the middle frontal gyrus. It is identified on the basis of multiple stains. A roughly circular area in the human, it is surrounded, except for its rostral tip, by area 9/46. It is equivalent to area 46 of Brodmann. Architectonically it is one of four parts of the dorsolateral prefrontal cortex. The others are area 8, area 9, and area 9/46 ( Petrides-2012 ).
     Its equivalent in the macaque is topologically similar, except that it is more oval in shape and is not embedded in area 9/46; it extends rostrally from area 9/46, ventral to area 9 and dorsal to area 12 ( Petrides-2012 ). As granular prefrontal cortex, it has no equivalent in the rat ( Zilles-2012 ).
