Guenon

The term Brodmann area 9 refers to a cytoarchitecturally defined portion of the frontal lobe of the guenon. Brodmann-1909 regarded it on the whole as topographically and cytoarchitecturally homologous to the granular frontal area 9 and frontopolar area 10 in the human. Distinctive features (Brodmann-1905): Unlike Brodmann area 6-1909, area 9 has a distinct internal granular layer (IV); unlike Brodmann area 6 or Brodmann area 8-1909, its internal pyramidal layer (V) is divisible into two sublayers, an outer layer 5a of densely distributed medium-size ganglion cells that partially merges with layer IV, and an inner, clearer, cell-poor layer 5b; the pyramidal cells of sublayer 3b of the external pyramidal layer (III) are smaller and sparser in distribution; the external granular layer (II) is narrow, with small numbers of sparsely distributed granule cells.[1]

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 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]
