Neural space analysis, pragmatic task (PT). (a,b) Trajectories in the 3D “neural space” formed by the first three principal components of PCA, during the pragmatic task (PT) performed by M1 (a) and M2 (b). The neural trajectories span the interval [−500, 800], with zero being the target onset, and each bin representing the average of 200 ms. Circles mark the beginning of the neural trajectories, crosses mark target onset, and squares mark the end of the neural trajectories. (c,d) Trajectories in the 1D space of the first 4 components of PCA (one panel for each component) for M1 and M2, respectively. Mean (coloured line) and variance (coloured shades) are shown.
