Fig. 6.

Force-dependent changes of gamma-beta activity averaged across task and effector side. Force-dependent contralateral power changes are separately displayed for each task in this figure. In both the early and late time window force increases with force level. The difference between power at the highest and lowest force level is significant in both windows. * denotes that power significantly differed between levels after controlling for multiple comparisons with FDR-correction (*< 0.05, **< 0.01).
