Followup experiments with more than two neurons should be interesting, to see whether graph arc destinations are remembered, or just the total. A far-fetched mechanism could be that each neuron transmits a signature (UID), that we've not detected because we've not been looking for it (perhaps it's slower than expected, taking hours to transmit it once...). It could include gross addressing information, based on chemical gradients at the time of its formation. I'm partial to the idea that neurons use more than just synaptic connections. It just seems too simple, especially when there's all that powerful cellular machinary (e.g. RNA transcription) just lying around...
