- ScienceDirect - Cognitive Brain Research : Increased dopamine tone during meditation-ind uced change of consciousness: ll participants reported a decreased desire for action during meditation, along with heightened sensory imagery. The level of gratification and the depth of relaxation did not differ between the attention and meditation conditions. Here we show increased striatal dopamine release during meditation associated with the experience of reduced readiness for action. It is suggested that being in the conscious state of meditation causes a suppression of cortico-striat al glutamatergic transmission.

- Feeling the Beat: Premotor and Striatal Interactions in Musicians and Nonmusicians during Beat Perception -- Grahn and Rowe 29 (23): 7540 -- Journal of Neuroscience: The authors propose that a cortico-subcor tical network including the putamen, SMA, and PMC is engaged for the analysis of temporal sequences and prediction or generation of putative beats, especially under conditions that may require internal generation of the beat. The importance of this system for auditory?motor interaction and development of precisely timed movement is suggested here by its facilitation in musicians.

- Reduced Caudate and Nucleus Accumbens Response to Rewards in Unmedicated Individuals With Major Depressive Disorder: Those with major depression showed significantly weaker responses to gains in the left nucleus accumbens and the caudate bilaterally. Also, anhedonic symptoms and depression severity were associated with reduced caudate volume bilaterally.

- Pure Pedantry : Neuroscience of Envy and Schadenfreude: "The degree of activation in the ACC from envy and the degree of activation in the ventral striatum from schadenfreude were positively correlated. Likewise, the degree of self-reported envy and schadenfreude were positively correlated. Both results suggest that the two feelings may be related."

But effective duration is so limited and stimulation of spinal cord might be more dangerous to cause side-effect. But their strategy might also open up the alternative possible strategies for curing diseases.
