If you have N neurons, you can simulate ANY possible topology of connections in a N x N matrix of weights. Of course with N of the order 10^13, we get a tape with some 10^26 values on it. The Turing machine needen't be too complex here, just read the values for each neuron and execute the neuron's response and learning functions. Very, very slow of course......
