Table 1.
Comparison of tSNR values across all twelve experimental conditions. The mean tSNR values are reported with the standard deviation being over volunteers. Significant differences between the PMC on and PMC off cases are indicated by * for p < 0.05 and ** for p < 0.01. Mean and standard deviation of the partition-weighted integrated motion values are shown in parenthesis. The partition-weighted integrated motion values were not significantly different for any of the PMC On vs PMC off cases.
