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…
Quantum decay of an open chaotic system: a semiclassical approach
Mathias Puhlmann, Holger Schanz, Tsampikos Kottos +1
We study the quantum probability to survive in an open chaotic system in the framework of the van Vleck-Gutzwiller propagator and present the first such calculation that accounts f…
The Intrinsic Time Scale of Transient Neuronal Responses
Bjoern Naundorf, Theo Geisel, Fred Wolf
In a generic neuron model, we present the linear response theory for the firing rate in response to both time dependent input currents and noise amplitudes. In both cases the signa…
Shot noise from action correlations
Holger Schanz, Mathias Puhlmann, Theo Geisel
We consider universal shot noise in ballistic chaotic cavities from a semiclassical point of view and show that it is due to action correlations within certain groups of classical…
Mesoscopic Rectifiers Based on Ballistic Transport: Playing off Classical against Quantum Mechanics
R. Fleischmann, T. Geisel
Recent experiments on symmetry-broken mesoscopic semiconductor structures have exhibited an amazing rectifying effect in the transverse current-voltage characteristics with promisi…
Signal Selection Based on Stochastic Resonance
Hans E. Plesser, Theo Geisel
Noise aids the encoding of continuous signals into pulse sequences by way of stochastic resonance and endows the encoding device with a preferred frequency. We study encoding by a…
