A Multi-modal Parcellation of Human Cerebral Cortex


Figure 8

Atypical splits of area 55b.   Here we show examples of a second type of topological incompatibility between the typical layout of areal features near area 55b and a minority of subjects with alternative 'split' layouts.  Row 1 shows the group average areal features: a, a d=40 RSN map corresponding to parts of the language network, b, a myelin map, c, a LANGUAGE Story-Baseline task contrast beta map, d, a d=40 RSN map corresponding to the dorsal visual stream, and, e, a mean curvature map illustrating the folding pattern.  The group delineation of areas 55b, FEF, and PEF are white or black lines.  f-j show these maps in a typical individual subject.  k-o show an atypical subject whose area 55b is split and FEF and PEF are joined.  p-t show a second atypical subject with a similar pattern.  In both cases the split of 55b is visible in multiple independent areal features.
