Establish whether temporal degeneracy analysis applies to stationary neuromechanical models

Establish whether the original temporal mutual-information analysis of degeneracy can be applied to neuromechanical models that exhibit a stationary regime.

Background

The paper adapts the Tononi–Sporns–Edelman framework from temporal ensembles to ensembles of parameter configurations because transient neuromechanical movements are non-stationary. Temporal analysis is therefore set aside for the class of models considered in the paper, although the authors note that it could remain applicable when a neuromechanical model satisfies the stationarity assumption.

The unresolved issue is whether the original time-based formulation can be meaningfully and reliably used for stationary neuromechanical systems, rather than replacing it with the configuration-based approach proposed here.

References

This methodological constraint applies only to tasks that fail the stationarity condition: the original temporal analysis remains open in principle for neuromechanical models that meet it.
