CAs formed prior to fast-mapping. A) CA examples. Each CA shows the cells belonging to it across the 12 areas, placed on a schematic illustration of the brain with the modeled cortical areas highlighted and color-coded. The color mapping between network areas and brain regions is shown in the schematic in the top right corner. Active cells are depicted as white dots in each gray area. Top-left is an example of the representation of a visual object referent. Top-right is an example of the correlates of a manual action execution. Bottom-left is an example of a phonological word form representation. B) Mean cell counts per area. CA cell counts shown in each area for word forms and referents averaged across 20 networks. Error bars depict standard error (SE). The colored outline of the bars maps them to their respective brain region. Cell counts for the object representations are shown in light gray and cell counts for action representations are shown in darker gray. Word form are later linked with either object or action representations and are split into separate bars on the basis of this future pairing, but the distinction is not meaningful at this point; hence, they all are depicted in gray with tilted stripes. In line with this, pairwise comparisons are only performed and shown for the referents. Depicted P-values have been Bonferroni-corrected. Asterisks illustrate significant differences between the number of neurons in CA circuits of object and action referents.
