> many different components of different structures > yup, he is building a brain The limbic system of the brain is made of many different structures. It handles much of the ancient fixed function instinctive operation of the brain -- heavily involved in sleep, reflexes, appetite, and motivation, for example. However, our general intelligence and learning capability is mostly due to our neocortex, which has a highly regular structure. The neocortex also subsumes the roles of much of the limbic system as development progresses, overriding the specific structures. This suggests to me that intelligence / learning doesn't benefit from specific structures, but from general structures, capable of encoding behaviour as data (by long-term potentiation of synaptic weights in the brain's case).
