(a) Electroencephalographic (EEG) recording configuration. Red elements represent the frontal channels (F3 and F4), the green ones represent the temporal channels (T3 and T4), and the blue ones represent the occipital channels (O1 and O2). CZ was used as a reference. (b) EEG theta power (µV²/Hz) per channel for each simulated scenario (n = 35). M: Mali, low complexity; A: Afghanistan, medium complexity; C: Outdoor test course circuit, high complexity. Error bars represent the SEM across participants. There were significant main effects of terrain complexity and channel (all p-values < 0.05).
