Summary

The goal of this study is to test whether voluntary up-regulation of mesolimbic reward system activation is possible, and to examine the neurobehavioral effects of specific neuromodulation of this circuit on reward processing. This goal will be achieved by testing the effects of a novel non-invasive experimental framework for neuromodulation that relies on neurofeedback (NF), which is guided by neuronal activation in the ventral striatum (VS) and interfaced with personalized pleasurable music as feedback. We Hypothesize that it is possible to learn to volitionally regulate the VS using this musical NF approach. We further predict that successful NF training for up-regulating the VS-EFP signal will result in marked changes in neural and behavioral outcomes associated with upregulation of dopaminergic signaling.

Brain-computer-interface: EEG-based musical Neurofeedback task

Neurofeedback training with EEG, in which participants are presented with self-selected music and requested to make the presented music sound better by applying mental strategies. Six repeated training sessions, each composed of five training cycles. Each cycle is composed of 120 sec of 'local baseline' block and 90 sec of 'regulation' block while listening to self-selected music. Participants are instructed to passively listen to their self-selected music during the 'local baseline' block, and to 'make the music sound better' during the 'regulation' block. Participants are instructed to recruit chosen mental strategies, which they find to be most efficient towards this regulatory task. During 'regulation', the quality of the sound varies in real-time (every 3 sec) in proportion to the difference between the current value of VS-EFP and its average value during 'local baseline'.
