I have very limited knowledge of how brains work, and I am being highly speculative, but from what little I know (correct me where I'm wrong) brains are a sort of massive interconnected network of signal receiving/transmitting units. It seems that the "paths" of logic would be crossed - that is a change somewhere could affect the logical path of signals far away from that change, perhaps even all signal paths. Has there ever been any sort of research into making some sort of special analog computer-like hardware that simulates brain activity or some sort of software that does this? Say by, creating some hardware unit or software construct that mimics the function of a grasshopper brain neuron, and interconnecting them in exactly the same configuration as they are connected in said grasshopper? (perhaps the connections themselves would need to model the connections within the grasshopper brain in speed and function) I am aware there are such things as "artificial neural networks" but a search on this indicates that they are typically not used to model actual brain function but rather to solve problems such as simple pattern recognition of very limited scope.
