Figure 3: Individual theta-based neurocognitive profiles are associated with vulnerability to nicotine self-administration.
A) Theta power increases over midfrontal sensors when smokers decide whether to self-administer nicotine. B) Cluster analysis yields 2 groups with opposite θ response profiles. C) Smokers showing higher θ responses during nicotine-related decisions (θ+) are more vulnerable to nicotine self-administration than smokers with the opposite neurocognitive profile.
