OSS-DBS: Open-source simulation platform for deep brain stimulation with a comprehensive automated modeling
Fig 2
Example of an initial human brain discretization in OSS-DBS.
The model is divided into the region of interest (ROI), the vicinity of contacts and the rest of the tissue (ROT). All three have their own submeshes with different element size requirements. Additionally, submeshes are defined for the electrode contacts and the encapsulation layer away from them. Controlled surface refinement of the contacts leads to a highly dense submesh around the electrode. Here, the active contacts are depicted in red, while the floating conductors are presented as blue cylinders.
