We hypothesized that audio-motor transformation (AMT) play an important role in voice-guided movement initiation with STN involvement. We propose AMT-related subthalamic nucleus activation analysis in lateralized PD for tremor asymmetry influence study. We identified PD symptoms laterality dependent STN activation peculiarities. Obligatory left STN activation in AMT supposes its role in motor command switching. Bilateral STN activation during the movement execution supports its proposed role as a motor error correction node.
