Yes, that's about right. An action potential (positive charge) is propagated along the neuron's axon, and then the presynaptic neuron sends an inhibitory or excitatory neurochemical message to the postsynaptic neuron. It's way, way more complicated than an electrical circuit--hence Ian's rejection of the "neurons are wires" metaphor.
