摘要: Abstract Background The globus pallidus internus (GPi) is the final output relay of basal ganglia for control movements but has also been shown to belong a second pathway projecting lateral habenula. This latter related reward processing. Method prompted us record, in eight patients receiving deep brain stimulation GPi alleviation various movement disorders, local field potentials (LFP) while these performed lottery task. task entailed choosing between higher and lower number, which changed their color after patient's choice with red (green) signaling loss (win, Euro cents) corresponding chosen number. Results Surface recordings showed feedback negativity from frontal midline site, time domain averages differential modulation depending on valence stimulus polarity inversion indicating that this reward-modulated activity was indeed generated locally. Furthermore, wavelet decomposition LFP reward-related response high beta/low gamma range. Conclusion We conclude human involved processing, possibly relation
