et al., 2005). In essence, activity within this network functions to attach emotional context and valence to cognitive cues. Neurocognitive tasks such as the gambling task used in our study which, apart from the cognitive evaluation of outcomes, also include a feeling or emotional component (e.g., loss, gain) could invoke specific interconnected regions of the PFC, ACC, and limbic structures, suggesting that when task demands modify emotional responses, neural responses occur within this network (Elliott et al., 2000; Liberzon et al., 2000). Further, activity throughout this circuit has been implicated in behavioral dispositions/disorders involving addictive-impulsive-compulsive spectrum, including alcohol/drug abuse, gambling, and risk-taking (Bechara, 2001; Cavedini et al., 2002; Mitchell et al., 2002; Rogers et al., 1999; Harris et al., 2008).
