1. A neural core circuit, comprising: a synaptic interconnect network including plural electronic synapses for interconnecting one or more source electronic neurons with one or more target electronic neurons; the interconnect network further including multiple axon paths and multiple dendrite paths, wherein each synapse is at a cross-point junction of the interconnect network between a dendrite path and an axon path; and a routing module maintaining routing information, wherein the routing module routes output from a source electronic neuron to one or more selected axon paths; wherein each synapse provides a configurable level of signal conduction from an axon path of a source electronic neuron to a dendrite path of a target electronic neuron.
