A key limitation to these paradigms is that they do not distinguish task - related activation in a single network from coactivation of distinct networks (Friston et al., 1996). (jneurosci.org)
Empirical evidence increasingly supports the hypothesis that patterns of intrinsic functional connectivity (iFC) are sculpted by a history of evoked coactivation within distinct neuronal networks. (semanticscholar.org)
Reducing coactivation is therefore one way in which strength can be increased, and it does seem to change with training (Tillin et al. 2011), although how much it contributes to increased force production is less clear (Buckthorpe et al. 2015). (strengthandconditioningresearch.com)
