Proportion of neurons correlated to the distance of the movement end-point (E) either from the body (dBE) or from the initial hand position (dHE). Values represent, for each epoch, the sum of the neurons (bottom part of each column, marked by the symbol ○) exclusively explained by a single factor (main effect in Table 3) and of those (top part of each column) explained prevailing by one of the two factors as resulting from the contrast (Fig. 6) obtained, using a winner-take-all rule, for those neurons with significant correlation (p < 0.05) for both factors. The white arrows indicate, for each column, the boundaries between the two classes of neurons. The prevailing effect of dHE is also evident considering only the main effect.
