processing, even when the stimuli is not consciously perceived by the individual. These data are also consistent with other investigations, suggesting that the anterior cingulate serves an indirect function by integrating emotional and attentional processing, and that the amygdala is specifically involved in detection and early processing of stimuli not available to conscious awareness (Morris et al., 1999). Individuals who smoke marijuana, even though not currently intoxicated, may experience a disruption or alteration of these networks which in turn affects the processing of emotional stimuli.
