Action Potential Onset Dynamics and the Response Speed of Neuronal Populations
B. Naundorf, T. Geisel, F. Wolf
The result of computational operations performed at the single cell level are coded into sequences of action potentials (APs). In the cerebral cortex, due to its columnar organizat…

Electrons in 2D periodic magnetic and electric fields: Avoided band crossings, metal-insulator transitions, and changes in the spreading direction
Björn Naundorf, Roland Ketzmerick
We study the energy spectrum and wave packet dynamics of electrons in a two-dimensional periodic potential subject to a perpendicular spatially modulated magnetic field. We observe…
