Figure 2: Here, we show the same robot again; the top row shows the wild
type robot. The lower row shows the robot re-growing, but here the growth
of the neural structure---neurogenesis---is suppressed. Note how the
interdependence between neurogenesis and morphogenesis leads to a modified
body plan when the neural structure is not allowed to grow. Click here to see the animation of the wild type
robot, and here to see the robot grown
without neural structure.
