Figure 5. Discrimination accuracies for single postures as represented by kinematic synergies.
Two clusters of similar postures are easily identifiable (i.e., precision grip and power grasps). However, other postures were recognized without showing an evident clustering, suggesting that the encoding procedure was not biased by a coarse discrimination of motor acts.
Figure 5—figure supplement 1. Workflow of the encoding analysis.
This diagram depicts the workflow of the multiple linear regression procedure applied on fMRI data using the matrices obtained from the data acquired in the kinematic and EMG experiments as encoding models. The pairwise discrimination accuracy was estimated in the decoding phase, represented as the final step of this diagram.
