Abstract :
Information transmission in a neuronal axon is based on electrical processes, which may be compared with the flow of a potential in a dielectric medium inside a cable. Commonly, this wave transition is described by a telegrapher´s equation & used extensively in structural analysis & modeling of a neuron. In this paper, a three pronged approach was adopted to investigate the relation between these propagating waves and Scalp EEG. Firstly, a unique continuous domain solution for the Current Wave propagation was obtained, and simulated in the frequency band 0-30 Hz. Then, Cortical Source natures were obtained from Scalp EEG by standard Low Resolution Brain Electromagnetic Tomography (sLORETA). Subsequently, the correlation between the spatial average of the current dipole sources obtained from sLORETA and the propagating neuronal current waves were explored.
