| Description |
English: Activation density heat maps. All images are sagittal views from the left. The image sections (A–C) represent the activation results of model I only, while section D comprises the data of all models (I–IV). (A) Voltage distribution (red-purple) generated by DBS simulation (stimulation amplitude: −1.5 V, pulse width: 60 μ s, stimulation frequency: 130 Hz). Brighter colors correspond to higher voltage amplitudes. (B) Fiber pathways (red) activated by the electric field that was generated by the voltage distribution in (A). (C) Activation density heat map, allowing for better identification of the main active fiber pathways. (D) Identification of active fibers pathways which are characteristic of a posterolateral (models I, II, pink color) or anteromedial (models III, IV, green color) DBS electrode placement. Yellow areas indicate an almost equal distribution between anteromedial and posterolateral stimulation. The associated mathematical operation is described in the running text. A, Anterior; P, Posterior; D, Dorsal; V, Ventral. |
