You don't need to appeal to "quantum effect" to think that being able to understand, well enough to simulate, THE SIMPLEST NEURAL SYSTEM of any organism would be helpful before jumping in feet first with 1 billion euros into the most complex neural system. Of course it is a process over 10 years and they have "only" spent 200 million so far. I would expect that quite a bit of that money is going to study model organisms from c. elegans to mouse to chimpanzee. Studying simpler model organisms is one of the best ways we have to understand fundamental biological principles.
