Show abstract
Digital representations of Purkinje cells from turtle cerebellum, which have long been to study cellular transmission dynamics and neuroplasticity, are necessary to conduct simulations of neuromodulation methods, including Transcranial Magnetic Stimulation (TMS). Methods: Data collected using microCT with 0.6 um isometric resolution are processed, segmented, and arranged to enable high resolution simulation via the Boundary Element Fast Multipole Method. Results: Fully computer aided design compatible, manifold triangular surface meshes were generated from microCT data and used to simulate cellular electromagnetic response to TMS. Conclusion: Accurate Purkinje cells may be readily generated and manipulated to create representative models of turtle cerebellum. Significance: The techniques employed herein may be used to generate accurate surface mesh of Purkinje cells which can enable computational electromagnetics code verification and serve as the basis for skeletal models used for bidomain biophysical simulations in tools such as NEURON to study neurostimulation dynamics and neuromodulation.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
