Is a neural network all that you would need to model in order to simulate a human's thoughts? How far are we from mapping a real brain to a simulation like thi

  Pretty far. We have only so far been able to simulate a part of a rats brain. Not even in real time. I'd love to present sources but i can't find them ATM. If anyone got links or corrections please do correct me. EDIT: Just ignore my previous statement. This is probably much more relevant: https://news.ycombinator.com/item?id=6157157 https://news.ycombinator.com/item?id=6157157 http://www.riken.jp/en/pr/press/2013/20130802_1/ http://www.riken.jp/en/pr/press/2013/20130802_1/

  It somewhat depends on what you think of as a neural network. For simple models no, state is vary important, as is signaling delays, hormones, and blood flow etc. Which means each neuron would individual be far more complex than what is generally used in computer science. Further brains are far from random so you would need to either copy someone or simulate the various developmental stages a person goes though. Finally, a neural network is pointless without some output so for anything beyond pretty pictures you need some sensory input's and some way to handle outputs. However, I have seen estimates that somewhere around a yottahert class computer working for a few years might be capable of simulating a brain sufficiently complex to hold an arbitrary conversation. Building the software capable of running such a simulation is another story.
