The effect of ionic diffusion on extracellular potentials in neural tissue
Geir Halnes, Tuomo Mäki-Marttunen, Daniel Keller +2
In computational neuroscience, it is common to use the simplifying assumption that diffusive currents are negligible compared to Ohmic currents. However, endured periods of intense…

On 1/f^alpha power laws originating from linear neuronal cable theory: power spectral densities of the soma potential, transmembrane current and single-neuron contribution to the EEG
Klas H. Pettersen, Henrik Lindén, Tom Tetzlaff +1
Power laws, that is, power spectral densities (PSDs) exhibiting 1/f^alpha behavior for large frequencies f, have commonly been observed in neural recordings. Power laws in noise sp…
