Paralimbic cytology compared to BNC along cytoarchitectural gradients. Regions included the posterior cingulate cortex (PCC, Vogt, 2009), pregenual anterior cingulate (pACC, Ongür et al., 2003; Vogt, 2009), and insula (Kurth et al., 2010; Ongür et al., 2003). For each region, a vector was drawn running from agranular to dysgranular to granular subregions. BNC was correlated with distance from the agranular/dysgranular end. We predicted that BNC would negatively correlate along this line. Statistics reported as Z-scores ± standard error, n.s. = non-significant.
