This genome is designed to scan and isolate each object in the environment
When a visual signal appears, it automatically activates the start_scanning cortical area. Start_scanning then triggers the bottom-left neuron to begin scanning in the 4 x 4 scanner and snoozes for an extended period while the 4 x 4 scanner runs on its own. Inside the 4 x 4 array, the initiated neuron activates the neuron to its right via the built-in sweeper connectivity rule. When the sweep reaches the top-right corner of the field of view, it reactivates the bottom-left neuron to restart the entire scanning process.
Both the original visual input and the 4 x 4 scanner project to the vision_sampler. Neurons in the vision_sampler fire only when PSPs from both sources are present; its firing threshold is set to the sum of the PSPs from the original visual input and the 4 x 4 scanner. Consequently, only objects within the scanner’s current frame appear in the vision_sampler. Other objects won’t appear until they are scanned. One limitation of this circuit is that objects appearing near the edge of the scanning frame may not be fully captured. Further refinement is needed to improve robustness.
