Can cocaine users self-regulate their dopaminergic reward circuit using neurofeedback?

We found evidence that people can upregulate their dopaminergic reward circuit using mental imagery. This works even better when they receive fMRI neurofeedback of their substantia nigra brain region. Interestingly, this also appears to work in cocaine users – at least in those without strong obsessive-compulsive drug use.

Like we showed in our study on the Aha!-moment, mentally generated feelings of reward can activate brain areas that produce dopamine. Could neurofeedback be a new form of self-guided cognitive brain stimulation?
