This is a bit of an open problem, to the point of being controversial. I'd hesitate to say anyone has a real answer even though we certainly have real experimental data. The philosophical takes range from:
* You never enter the same room twice.
* Your brain partially re-wires every time you sleep.
* Your brain rewires, but the way it rewires is surprisingly predictable and we can track the dynamics.
* Your brain is rewiring literally every second, but not every rewiring is functional - does this imply an implicit robustness?

Etc, etc.
