10 years showed atypical trajectories of frontal no-go theta power (possibly delayed frontal cortical maturation and synaptic pruning in neural circuits involved in response inhibition) and heightened levels of impulsivity and sensation seeking (ie, behavioral disinhibition). There also is the possibility that frontal no-go theta activity might mediate the relation between early sexual abuse and impulsivity; the timing of the assessment of trauma exposure, impulsivity (BIS and SSS), and no-go frontal theta oscillation preclude the testing of this hypothesized mediation model in the present study. Future studies are needed to disentangle the influence of behavioral aspects of impulsivity with frontal theta oscillatory activity during response inhibition in the context of trauma exposure.
