Fig. 3: Decoding tongue shape from motor cortex.
From: Robust cortical encoding of 3D tongue shape during feeding in macaques
a Decoded (colored lines) and ground-truth (grey lines) kinematics of the first 7 principal components of tongue shape (PCA of Procrustes-transformed marker positions), each independently decoded for a subsection of a representative test trial. The colored bar at the top of the figure indicates the behavior being performed. S2T denotes stage 2 transport (See Supplementalary Methods for detail on gape cycle types.) b Mean decoding accuracy (R2), by variable, for both subjects. Each bar represents the mean decoding accuracy for that variable across the cross-validation folds (n = 6). Error bars represent ±1 standard deviation.
