Complete electrode model in EEG: relationship and differences to the point electrode model.
In electroencephalography (EEG) source analysis, a primary current density generated by the neural activity of the brain is reconstructed from external electrode voltage measurements. This paper focuses on accurate and effective simulations of EEG through the complete electrode model (CEM). The CEM allows for the incorporation of the electrode size, shape and effective contact impedance into th...

Intercellular signaling is crucial for embryonic patterning, cell specification and tissue induction. Hedgehog (Hh) encodes a secreted signal originally identified in Drosophila (Nüsslein-Volhard and Wieschaus, 1980). Vertebrate family members have been subsequently isolated (Echelard et al., 1993; Ekker et al., 1995; Krauss et al., 1993; Riddle et al., 1993; Roelink et al., 1994). In vivo and ...
متن کاملComplete Electrode Model of Electrical Impedance Tomography: Approximation Properties and Characterization of Inclusions
In electrical impedance tomography one tries to recover the spatial admittance distribution inside a body from boundary measurements. In theoretical considerations it is usually assumed that the boundary data consists of the Neumann-to-Dirichlet map; when conducting realworld measurements, the obtainable data is a linear finite-dimensional operator mapping electrode currents onto electrode pote...
متن کاملEIT image reconstruction based on a hybrid FE-EFG forward method and the complete-electrode model.
This paper presents the application of the hybrid finite element-element free Galerkin (FE-EFG) method for the forward and inverse problems of electrical impedance tomography (EIT). The proposed method is based on the complete electrode model. Finite element (FE) and element-free Galerkin (EFG) methods are accurate numerical techniques. However, the FE technique has meshing task problems and th...
متن کاملA Complete and Highly Flexible 256-Electrode Retinal Prosthesis Chip
This paper presents a highly flexible and complete 256-electrode retinal prosthesis chip, which is small and ready for packaging and implantation. The chip contains 256 separate programmable drivers each of which is dedicated to its own electrode for flexible stimulation. The stimulator possesses a wide range of stimulation features, supporting various stimulation strategies. Many safety featur...
