If each simulated "neuron" is just a linear threshold unit, as described by the paper, using a whole process to run it and exchange messages by UDP looks like a terribly wasteful architecture.
Maybe the author wants to eventually implement a computationally expensive biologically accurate neuron model, but still I don't see the point of this architecture, as even if the individual neurons were biologically accurate, the overall simulation wouldn't, due to the non-deterministc delays and packet lossess introduced by UDP messaging.
I'm unimpressed.
The connectome for the 302 neurons of the nematode C. elegans was put in charge of a Lego robot. Without any additional programming, the simulated brain started using the robot parts just like the original worm's organs.
"When you think about it, the brain is really nothing more than a collection of electrical signals."
