This paper proposes an intermediate: a relatively simple calculus describing how assemblies of neurons work, which is both biologically plausible and at the same time capable of performing small intersting tasks in simulations. Their Assembly Calculus is computationally universal: you can compile'' any Turing machine into an assembly of neurons. At the same time, it's capable of learning and they show a simple experiment in training an assembly for language generation.
