Population dynamics during the sensory stimulus Epoch

(A) Ratio of explained variance of the first five PCs in Integ-subspace.

(B) Neural trajectories in the three-dimensional subspace spanned by integ-PC1, integ-PC2, and integ-PC3. The blue and gray curve sets correspond to the neural trajectories in the color and motion contexts, respectively. Stars and circles indicate the start points and endpoints, respectively. The black dash curves connecting the endpoints mark manifold ${\mathcal{M}}_{color}$ and ${\mathcal{M}}_{motion}$, respectively.

(C) Polar histograms of the angles between four task-related axes and Integ-subspace.

(D) Neural trajectories in the two-dimensional subspace spanned by integ-PC2 and integ-PC3. The blue dashed line represents the projection of the C-cue-axis and the dark blue solid circle denotes the center point of the projection. The gray dashed line represents the projection of the M-cue-axis and the orange solid circle denotes the center point of the projection.

(E) The angles between integ-PC1 and the C-cue-axis (blue) or M-cue-axis (gray) in 20 trials.
