Figure 1

Perceptual cognits are organized hierarchically between primary sensory areas (blue) and posterior association cortex (white) by order of category of perceptual memory, from phyletic sensory memory (sensory cortex) at the bottom to conceptual perceptual knowledge at the top. Executive cognits are organized hierarchically between primary motor cortex (red) and prefrontal cortex (white) by order of category of executive memories, from phyletic motor memory (motor cortex) at the bottom to conceptual executive knowledge at the top.

Lower figure: Lateral view of the left hemisphere, areas numbered according to Brodmann’s cytoarchitectonic map. RF: Rolandic fissure.

Upper figure: Schematic hierarchical order of perceptual and executive cognits. Bidirectional arrows indicate cortico-cortical connectivity: perceptual (dark blue), executive (red), and perceptual-executive (green). The inverted triangles symbolize the divergence of connections and increased size of cognits with ascending hierarchical order.
