3D illustration of all active electrode contacts: a, b. Electrode position of 57 PD patients (a):Electrode position, posterior view;(b):active contact,posterior view; (The blue dots represent group I (DBS improvement rates < 25%), the white dots represent group II (DBS improvement rates between 25 and 50%) and the red dots represent group III (DBS improvement rates> 50%).). c relationship between volume of tissue activated (VTA) in STN. (Yellow: STN. Red: red nucleus. Green: Gpi. Blue: Gpe.). d relationship between volume of tissue activated (VTA) in STN subregions. (Dark yellow nucleus: STN motor subregion. Blue nucleus: STN associative subregion. Pale yellow nucleus: STN limbic subregion. Red nucleus: red nucleus)
