= 2.92 (0.03); F = 11.38; p = 0.0008]. Further, this 3-way interaction suggested that males showed higher theta power during loss compared to gain (loss > gain) in frontal regions [loss = 3.05 (0.03); gain = 2.94 (0.03); F = 21.04; p < 0.0001] and an opposite pattern (gain > loss) in central [loss = 3.05 (0.03); gain = 3.10 (0.03); F = 6.00; p = 0.0144], parietal [loss = 3.05 (0.03); gain = 3.18 (0.03); F = 38.42; p < 0.0001], and occipital region [loss = 2.98 (0.03); gain = 3.12 (0.03); F = 53.43; p < 0.0001]. On the other hand, the same 3-way interaction revealed that females showed significantly more theta power for gain than for loss (gain > loss) in central [loss = 2.92 (0.03); gain = 3.10 (0.03); F = 77.87; p < 0.0001], parietal [loss = 2.98 (0.03); gain = 3.17 (0.03); F = 94.52; p < 0.0001], and occipital regions [loss = 2.90 (0.03); gain = 3.10 (0.02); F = 108.93; p < 0.0001]. Pairwise comparison across gender (male vs. female) shown in Fig 3 [panel sets B1 and B2] revealed more specific findings. Younger males (both HR and LR groups) displayed
