Finite Element Modeling for Extracellular Stimulation
نویسندگان
چکیده
Definition Finite element modeling is an important computational tool in neural engineering to simulate neural excitation with implanted electrodes or with surface electrodes. Besides its importance for analyzing artificially generated neural activities, e.g., in the spinal cord (Danner et al., 2014; Hofstoetter et al., 2014), this technique is useful to interpret recorded electrical biosignals generated by neural or muscle tissue activities.

Effects of Microelectrode Array Configu- Ration and Position on the Threshold in Electrical Extracellular Stimulation of Single Nerve Fiber: a Modeling Study
A transient finite-element model has been presented to simulate extracellular potential stimulating in a neural tissue by a nonplanar microelectrode array (MEA). This model allows simulating the extracellular potential and transmembrane voltage by means of a single transient computation performed within single finite element (FE) software. The differential effects of the configuration and posit...
متن کاملCurrent approaches to model extracellular electrical neural microstimulation
Nowadays, high-density microelectrode arrays provide unprecedented possibilities to precisely activate spatially well-controlled central nervous system (CNS) areas. However, this requires optimizing stimulating devices, which in turn requires a good understanding of the effects of microstimulation on cells and tissues. In this context, modeling approaches provide flexible ways to predict the ou...
متن کاملEvaluation of Ultimate Torsional Strength of Reinforcement Concrete Beams Using Finite Element Analysis and Artificial Neural Network
Due to lack of theory of elasticity, estimation of ultimate torsional strength of reinforcement concrete beams is a difficult task. Therefore, the finite element methods could be applied for determination of strength of concrete beams. Furthermore, for complicated, highly nonlinear and ambiguous status, artificial neural networks are appropriate tools for prediction of behavior of such states. ...

متن کاملFinite element modeling of polymer matrix nano-composites reinforced by nano-cylindrical fillers
A new three-dimensional unit cell model has been developed for modeling three constituent phases including inclusion, interphase and matrix. The total elastic modulus of nano-composite is evaluated. Numerical results are in good agreement with the previous proposed theoretical modeling. Higher matrix and inclusion elastic modulus both can dramatically influence the total elastic modulus.
