Growth and Signaling Image Sequences
of a 24*24*24 3D CA Cell CAM-Brain Machine
(CBM) Neural Net Module
The following sequence of images shows the growth and signaling phases of a cube of 24*24*24 3D CA cells which form a CAM-Brain Machine (CBM) neural network module. The first sequence shows the growth phase. The initial red cells are the neurons, whose initial positioning is under genetic control. The axons (blue) and dendrites (green) grow in alternating steps, one clock tick at a time.
The module shown here was evolved to detect the direction of motion of a moving horizontal line that moved either up or down one of the cube's input faces. The binary signals flowing through the cube are shown in white. The module was evolved to produce a strong output signal if the line moved upwards and a weak output signal if the line moved downwards. The module evolved well and in a few seconds on the CBM. I have no idea how the evolved circuit does what it does, but it works. That is the strength of the evolutionary engineering approach.
