Abstract

A solution of the direct problem of electroencephalography was carried out within the framework of multilayer sphere model consisting of homogenous omic spherical kernel covered with five omic layers modelling epicortical liquor, three-layer bone of the skull, scalp. Solutions of more simple models cited in literature are particular variants of this general one. By means of numerical simulation solutions of multilayer spheres of different complexity are compared and a notion of the simplest adequate model is worked out.

A Kalman filter based methodology for EEG spike enhancement.

In this work, we present a methodology for spike enhancement in electroencephalographic (EEG) recordings. Our approach takes advantage of the non-stationarity nature of the EEG signal using a time-varying autoregressive model. The time-varying coefficients of autoregressive model are estimated using the Kalman filter. The results show considerable improvement in signal-to-noise ratio and significant reduction of the number of false positives.

Visual evoked potential in the newborn: does it have predictive value?

We reviewed studies on the predictive value of visual evoked potentials (VEPs) in the newborn. VEPs demonstrated a good correlation with neurodevelopmental outcome in full-term infants with birth asphyxia. However, their prognostic value in preterm infants is controversial. In preterm infants, most studies showed high specificities for neurodevelopmental outcome, but some studies demonstrated lower sensitivities.
