Uberon term
'insular cortex' http://purl.obolibrary.org/obo/UBERON_0034891

Suggested textual definition
The insular cortex (also insula and insular lobe) is a portion of the cerebral cortex folded deep within the lateral sulcus (the fissure separating the temporal lobe from the parietal and frontal lobes) within each hemisphere of the mammalian brain. It is the primary gustatory cortex and is involved in sensorimotor and somatosensory as well as socioemotional functions.

Uberon term
'Brodman (1909) area 9' http://purl.obolibrary.org/obo/UBERON_0013540

Suggested textual definition
Brodmann area 9, or BA9, refers to a cytoarchitecturally defined portion of the frontal cortex in the brain of humans and other primates. It contributes to the dorsolateral and medial prefrontal cortex and plays a role in executive functions such as working memory, planning, inhibition, decision-making, and reasoning. Its cytoarchitecture is referred to as granular due to the concentration of granule cells in layer IV. 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.
