abstract = {Connectivity changes after brain lesions due to stroke are
tightly linked to functional outcome. Recent analyses of
fMRI time series indicate that dynamic functional network
connectivity (dFNC), reflecting transient states of
connectivity may capture network-level disruptions distant
to the lesion site. Yet, the relevance of such dynamic
connectivity patterns for motor recovery remains unclear.
We, therefore, combined the analysis of static and dFNC and
a repetitive transcranial magnetic stimulation (rTMS) lesion
approach, to test whether dFNC provides region-specific
insight into motor system reorganization after stroke. We
focused on the contralesional primary motor cortex (M1) and
anterior intraparietal sulcus (aIPS), two regions previously
shown to modulate motor performance post-stroke in a time
dependent manner. In 18 individuals in the chronic phase
after stroke (with either persistent or recovered deficits)
and 18 healthy participants, we analyzed static and dynamic
resting-state connectivity. We then applied online rTMS
intereference over contralesional aIPS and M1 during hand
movement tasks to assess region-specific contributions to
motor behavior. Consistent with previous studies, dFNC
states were associated with persisting motor deficits,
whereas static connectivity was not associated with motor
outcome. dFNC but not static connectivity was associated
with residual motor deficits and explained TMS-induced
behavioral changes, when applying rTMS over contralesional
M1. For contralesional aIPS, both static and dynamic
connectivity were linked to TMS effects. This indicates that
dFNC - more than static connectivity - contains information
on the functional relevance of brain regions for motor
outcome, specifically contralesional M1. Our results
highlight the added value of temporal network analysis in
understanding mechanisms of stroke recovery mechanisms.},
