Contralateral reward information appears earlier than ipsilateral reward information in amygdala and BF. A, Population reward-contra (cyan) and reward-ipsi (magenta) discrimination curves as function of time relative to cue onset for amygdala sites. Firing rate differences were peak normalized and sign corrected before averaging over recording sites. The optimal time shift between the curves was determined using data within 50–400 ms after cue onset; an extended time window is plotted only for display purposes. B, Same as A for the BF sites. Latencies differed significantly for each brain area (p < 10⁻³).
