They incorporate cascade effects to increase or decrease their sensitivity and this final piece of the puzzle the researchers have just discovered describes how the different structures in the brain adopt different analog and digital processing capacities. Among other things it suggests that at any given time people should adopt one of four rudimentary approaches to problem solving and their neurons should do the same both individually and collectively. Once we have a systems logic that can describe how these four rudimentary approaches overlap it would provide the architecture for how to produce an AI.
