Before revision:  The method is validated by using the membrane potential obtained from numerical simulations of neuronal motifs that mimic extracellular brain activity, similar to the experimentally measured local field potential. When excitatory and inhibitory synapses are not mixed, the method correctly predicts the type of synapses that participate in the signaling.
After revision:  The method is validated in a neuronal population model, testing the paradigm that excitatory and inhibitory synapses are not mixed, the method correctly predicts the type of synapses that participate in the signaling.
