We quantitatively evaluated
the evolution of altered probability% of dynamic functional connectivity in
seven states at Pre-focused ultrasound (FUS), FUS-35min, and FUS-3hr, suggesting the potential of FUS-neuromodulation.
Figure
3. (a) The
correlation coefficients
of 7 centroids represented 7 states of dynamic functional connectivity of Pre-FUS,
FUS-35min, and FUS-3hr groups. (b,c) The
bar charts and spider chart illustrated the probability of 7 states occurring
in each group.

ROI. (c)
To evaluate
dynamic FC maps,
a sliding window method was performed to calculate Pearson’s
correlation coefficients between 36 ROIs.
(d) 36 ROIs were divided into 9 groups on FC map.
