Fig. 4: The evolution of value and choice signals in SC activity across 3 menus.

a Normalized neuronal activity was segregated based on the rank value of the target in the response field and whether a saccade was ultimately directed to the response field target (solid lines) or a target outside the response field (dashed lines). Otherwise, the same format as Fig. 3. b The evolution of the population regression coefficients for value ranking (black) and choice direction (gray). There is no value plot in the rightmost 1-value remaining panel because all remaining targets had the same, lowest value. The time points with statistically significant regression coefficients by value ranking (black dots) and choice direction (gray dots) was shown at the bottom of the panel (t test, P < 0.05, with false-discovery rate correction). c The evolution of neuronal choice selectivity toward targets of different value rankings. The receiver-operating characteristic analyses were done between activities associated with choices toward the response field target versus targets outside the response field that shared the same value. All shaded regions represent SEM.
