Learn how to build realistic brain tissue models and test their predictions
Mechanical stability is a crucial requirement for the long-term functioning of recording brain electrodes. Stresses caused by displacements between the tissue and an electrode are believed to be detrimental to the implant’s function. Current simulation results point towards the role of respiration and blood vessel pulsation as the main factors interacting with the implant. The topic will develop a technique to estimate forces and stresses impressed on brain tissue by an implanted electrode during normal physiological activity. As a starting point, the student will refine the existing FEM model of an implant immersed in soft tissue phantom (see images).
Specifically, the student will develop more realistic blood vessel models in a simplified tissue geometry. Based on the outcome of the simulation study, the student will produce an up-scaled tissue phantom and improve the existing experimental setup.
