The simulator used is called Neuron. Code for it is written in a custom language called Hoc and models are implemented in yet another domain specific language. Hardcoded parameters galore including whole sections of code that are prefaced with: this has been copied from this other publication.

The dendritic tree geometry is specified as hardcoded set of point and branch declarations

(apparently that morphology was reconstructed from imaging data?)
It is also not true that no progress has been made in the understanding of String Theory in the last 40 years and it still seems like the best bet that could eventually generate a fundamental theory. What is missing is still a lot though:
- We don't seem to possess the correct mathematics to develop a non-perturbative formulation of String Theory and there are too many potential string backgrounds that we could expand around.
- It is also hard to derive the matter content of low energy effective actions from most brane configurations.
String theory provided major insight into non-perturbative quantum field theory as well. There is tons of examples, let me highlight one of them: The discovery of the Amplituhedron (Arkani-Hamed et al., 2012) was preceded by the discovery of the BCFW recursion relation (Britto et al., 2005), which in turn was motivated a relationship between perturbative Yang-Mills theory and the instanton expansion of a certain string theory in twistor space (Witten, 2003).
It was well understood also that any European bureaucracy would be dominated by Frenchmen, because they simply were the best.
