Abstract

The main anatomical features of mammalian telencephalic cortexes are examined as related to the morphology of electroencephalogram (EEG) signals. Theories of the EEG genesis are rewieved, starting from the early works of the thirties to nowadays. Sinaptic and neuron based models are criticised at length on behalf of their laching predictive properties. A computer simulation of EEG laminar analysis results is enterprised, basing on a new model conceived by one of the authors. In this model the role of non-neuronal (glia) cells is taken into account, and EEG signals are interpreted as the effect of ion waves propagating through the cortical medium. The results of the simulation are compared to experimental patterns of laminar evoked potentials. An anatomo-physiological hypothesis concerning the location and constitution of EEG wave sources in the cerebral cortex is formulated, to account for the numerical values provided by the model.
