Anatomical terms of neuroanatomy |
Brodmann area 9, or BA9, refers to a cytoarchitecturally defined portion of the frontal cortex in the brain of humans and other primates. Its cytoarchitecture is referred to as granular due to the concentration of granule cells in layer IV.[1] It contributes to the dorsolateral and medial prefrontal cortex.
Functions
The area is involved in short term memory,[2] evaluating recency,[3] overriding automatic responses,[4] verbal fluency,[5] error detection,[6] auditory verbal attention,[7] inferring the intention of others,[8] inferring deduction from spatial imagery,[9] inductive reasoning,[10] attributing intention,[11] sustained attention involved in counting a series of auditory stimuli,[12] and displays lower levels of energy consumption in individuals suffering from bipolar disorder.[13]
The area found on the left hemisphere is at least partially responsible for empathy,[14] idioms,[15][16] processing pleasant and unpleasant emotional scenes,[17] self criticisms[18] and attention to negative emotions.[19]
On the right hemisphere the region is involved in attributing intention,[20] theory of mind,[21] suppressing sadness,[22] working memory,[23][24][25] spatial memory,[26][27] recognition,[28][29][30] recall,[29][31][32] recognizing the emotions of others,[33] planning,[34] calculation,[35][36] semantic and perceptual processing of odors,[37] religiosity,[38] and attention to positive emotions.[19]
