NCT03170258

Brief Summary

The purpose of this study is to see if a non-medication intervention can increase motivation and reward processing to non-drug reward cues (for example, a picture of one's favorite food) in individuals with and without nicotine dependence by observing brain activity using electroencephalography (EEG) and/or functional magnetic resonance imaging (fMRI). The investigators hypothesize that learning to increase brain activity to non-drug cues may improve reward responses and motivation to non-drug cues, and for individuals who smoke, may eventually result in improved smoking cessation outcomes.

Outcome Measures

Primary Outcomes (2)

  • Percent Change in Reward-related Brain Activation as Measured by fMRI

    The investigators will examine the change in brain activation in the target region (e.g., VTA) during the task. This includes prior to, during, and following real-time neurofeedback. Reported is the percent signal change from baseline (last 3 volumes of prior count condition).

    Changes will be assessed across the task (~30 minutes) during the neurofeedback visit

  • Change in Reward-related Brain Activation as Measured by EEG Ratio of Beta to Theta Power

    The investigators will examine the change in brain activation in the target region (e.g., VTA) during the task. This includes prior to, during, and following real-time neurofeedback. Reported here is the change from baseline (prior to real-time neurofeedback) and \~30 minutes following real-time neurofeedback. The ratio of Beta to Theta power indicates the level of active brainwave activity (Beta) versus the level of resting brainwave activity (Theta).

    Baseline (prior to real-time neurofeedback) and ~30 minutes following real-time neurofeedback

Secondary Outcomes (2)

  • Dopamine Availability

    Collected once during the screening visit

  • Onset to Smoking a Cigarette

    up to 30 minutes following the neurofeedback session

Study Arms (2)

Reward-related Brain Region Feedback

EXPERIMENTAL

Participants in this group will receive neurofeedback from a reward-related brain area (e.g., VTA, PFC) using EEG and/or fMRI during the experiment.

Device: Neurofeedback (from fMRI and/or EEG)

Noise Control

SHAM COMPARATOR

Participants in this group will receive sham neurofeedback. Participants will be debriefed at the end of the study.

Device: Neurofeedback (from fMRI and/or EEG)

Interventions

During part of the task, a feedback display (e.g., thermometer stimulus) will be used to display the average brain activity for each participant. This signal will be acquired \~ every 1 second during the neurofeedback session and will dynamically update to reflect ongoing changes in brain activity. This continuously updated display is the primary feedback mechanism provided to the participant.
