2020, NeuroImageCitation Excerpt :Measurements were obtained with respect to a reference electrode, 9 mm in diameter, placed over the dorsal surface of the cerebellum. Tissue conductivity was assumed to be isotropic throughout the cerebral grey matter (0.3 Sm-1) and white matter (0.15 Sm-1), and the conductivity of the cerebrospinal fluid (CSF) was set at 1.79 Sm-1 (Ranck, 1963; Baumann et al., 1997; Latikka et al., 2001) (compiled from literature by Horesh (2006)). The time-difference EIT approach was employed for imaging, based on the principle that modelling errors are largely cancelled out when a reference baseline measurement is subtracted from the data measurement (Brown, 2003).

2018, NeuroImage: ClinicalCitation Excerpt :Measurements were obtained with respect to a reference electrode, 9 mm in diameter, placed over the dorsal surface of the cerebellum. Tissue conductivity was assumed to be isotropic throughout the cerebral grey matter (0.3 Sm−1) and white matter (0.15 Sm−1), and the conductivity of cerebrospinal fluid was set at 1.79 Sm−1 (Ranck, 1963; Baumann et al., 1997; Latikka et al., 2001) (compiled from literature by Horesh (2006)); summarised by Jehl et al. (2015b))). An inversion of the resulting Jacobian matrix was used to solve the inverse problem.
