Stimulus evoked BOLD fluctuations and correlated resting
state BOLD signal was detected robustly in spinal cord WM. Resting state WM correlations
followed a trend which mimicked spinal cord functional recovery after an
injury. (33 words)
Figure4: (A) Connectivity
matrix (absolute
values) averaged
over
15 runs of 5 monkeys at
different
time points (Pre-SCI, Post-SCI Stage1 (2 weeks), Post-SCI Stage2 (7-8 weeks)
and Post-SCI Stage3 (16-22 weeks). (B) Box-plot
of the connectivity values at different time points . The dotted line joins the
median of the box-plots. Significantly different box-plots using Wilcoxon
non-parametric test are denoted by * (p<0.05) and ** (p<0.01) .

5: (A)
Mean
+/- SD of power
spectra (0.01-0.1Hz) of all ICs (averaged
over 15 runs of 5 monkeys ) at pre-and post-SCI stage 1. The shaded bar denotes
the region where the drop in connectivity is conspicuously observed.(B)
Mean
of all IC’s power spectra at different time points i.e. pre- and post SCI
stage1-3. (C)
Box
plot of averaged (0.01-0.1 Hz) spectral power for all ICs at different time
points. The
dotted line joins the median of the box-plots. Statistically significant difference
using Wilcoxon non-parametric test are denoted by * (p <.05) and **
(p<.01).
