MCP, mid-commissural point; AC-PC, anterior commissure to posterior commissure length; B, bilateral; VPL, ventral posterolateral; PAG, periaqueductal gray; R, right; L, left; VPM, ventral posteromedial

Note: Along the x-axis, positive coordinates indicate positioning to the right of the origin; along the y-axis, positive coordinates indicate anterior positioning relative to the origin; along the z-axis, positive coordinates indicate superior positioning relative to the origin
