On December 17, 2023, a new research article entitled "Cytoarchitectonic and connection stripes in the dysgranular insular cortex in the macaque monkey" was published in The Journal of Comparative Neurology by the Evrard Lab of ICPBR (Center for Excellence in Brain Science and Intelligence Technology, Chinese Academy of Sciences). This research article reports the tight overlap of tract-tracing labeling patterns and cytoarchitectonic subareas in the macaque monkey dysgranular insular cortex. This overlap supports the lab’s previous hypothesis that the primate insular cortex is highly organized, with separate dysgranular “stripes” possibly integrating interoception with functionally distinct ‘egocentric’ (self-agency) and ‘allocentric’ (social) exteroceptive modalities.
Figure description: Overlap of the tract tracing labeling pattern (left and middle panels) with the Nissl cytoarchitectonic subareas (right panel) in a pair of adjacent coronal sections of the insular cortex one representative case with injection of Lucifer Yellow in cingulate area 24b’. Lateral is to the right. Dorsal is to the top. Scale bar = 1 mm.
