Convergence-divergence architecture

The convergence-divergence architecture can be used to recall memories prompted by a specific visual stimulus. In panels a and b, a certain incoming visual stimulus (selective set of small filled-in boxes) prompts forward activity in CDZs of levels 1 and 2 (bold arrows and filled-in boxes). In panel c, forward activity activates specific CDRs, and in panel d, retroactivation from CDRs prompts activity in early somatosensory, auditory, motor, and other visual cortices (bold arrows, filled-in boxes). Retroactivation generates displays in “image space” as well as movement (selective set of small filled-in boxes) (Damásio, Self comes to mind, 2010, p.115)
