Table 1 Connectivity differences vs. random surrogate differences

From: Walking reduces sensorimotor network connectivity compared to standing

Sensorimotor differences (surrogate) 0.8 m/s – 0.0 m/s 1.2 m/s – 0.0 m/s
Passive -13.38% (-7.62 ± 4.91%)* -20.64% (-9.57 ± 5.40%)*
Active -9.31% (3.87 ± 6.16%) -7.73% (2.06 ± 5.32%)
Non-sensorimotor differences (surrogate) 0.8 m/s – 0.0 m/s 1.2 m/s – 0.0 m/s
Passive -0.52% (-8.09 ± 2.06%) 3.67% (-9.61 ± 2.24%)
Active 20.74% (4.09 ± 2.40%)* 15.63% (2.21 ± 2.11%)*
  1. Each surrogate difference is calculated by averaging randomized connections (across all regions) over 1000 iterations. This is why the surrogate connectivities, in (), are the similar for both sensorimotor and non-sensorimotor regions. The variances are larger however, because the sample size (2 regions as opposed to 3) is smaller. Here statistical significance is indicated if any values deviate considerably from the surrogate average. We see that all results vary at least 1 STD from the surrogate mean (blue) and most deviate > 2 STD from the surrogate mean (green). * indicates as significant change from 0.
