Definition
Extracellular electrical neural stimulation consists in injecting a current through an electrode located in a neural tissue. A potential field is created in the tissue, which influences the membrane potential of neural elements. The membrane response depends on the shape of the potential field around the neuron, which depends itself on the electrode configuration. Finite element models (FEM) are numerical models that can be used to compute the potential field and predict the effect of a given electrode configuration. These models are based on a description of the geometry and the electrical properties of the conductive media and specific constraints on their boundaries.
Detailed Description
Electrical stimulation of neural tissues has been extensively used for decades. More recently, an increasing interest has grown to build neural prosthesis based on arrays of microelectrodes to restore functional activity in the damaged central nervous system. The fine use of electrical...
