These architectures are hardware implementations of simple integrate-and-fire-related architectures. You can usually implement simple plasticity algorithms like spike-timing dependent plasticity. They don't exceed ANNs at this point, but are closer to biological neurons. Some researchers are looking into how the backpropagation of errors might be implemented in spiking networks.
