  • Stereotactic coordinates of subthalamic leads’ contact 1 were rendered according to the anterior commissural–posterior commissural (AC–PC) line and the mid-commissural point (MCP) between AC-PC line; x = mm lateral from AC-PC line; y = mm anterior (+) or posterior (–) from MCP; z = mm depth according to AC–PC line (–, if ventral; +, if dorsal). Differences were considered significant if p < 0.05. Data were expressed as mean ± SD.
