Kinetics of Atrial Repolarization Alternans in a Free-Behaving Ovine Model

Jean-Marc Vesin, Florian Jousset, Etienne Pruvot

Kinetics of Atrial Repolarization Alternans. Introduction: Repolarization alternans (Re-ALT), a beat-to-beat alternation in action potential repolarization, promotes dispersion of repolarization, wavebreaks, and reentry. Recently, Re-ALT has been shown to ...

Parameter extraction and classification of three cortical neuron types reveals two distinct adaptation mechanisms

Wulfram Gerstner, Carl Petersen, Richard Naud, Skander Mensi, Christian Antonio Pozzorini, Michael Avermann

Mensi S, Naud R, Pozzorini C, Avermann M, Petersen CCH, Gerstner W. Parameter extraction and classification of three cortical neuron types reveals two distinct adaptation mechanisms. J Neurophysiol 107: 1756-1775, 2012. First published December 7, 2011; do ...

Gate-controlled linear magnetoresistance in thin Bi2Se3 sheets

Klaus Kern, Marko Burghard, Pascal Gehring

We explore the emergence of linear magnetoresistance in thin Bi2Se3 sheets upon tuning the carrier density using a back gate. With increasingly negative gate voltage, a pronounced magnetoresistance of similar to 100% is observed, while the associated B-fie ...

Synaptic Mechanisms Underlying Sparse Coding of Active Touch

Carl Petersen, Sylvain Crochet, Yves Emile Alfred Kremer, James Poulet

Sensory information is actively gathered by animals, but the synaptic mechanisms driving neuronal circuit function during active sensory processing are poorly understood. Here, we investigated the synaptically driven membrane potential dynamics during acti ...

Active strain and activation models in cardiac electromechanics

Alfio Quarteroni, Ricardo Esteban Ruiz Baier, Simone Rossi

We present a model for mechanical activation of the cardiac tissue depending on the evolution of the transmembrane electrical potential and certain gating/ionic variables that are available in most of electrophysiological descriptions of the cardiac membra ...

Mechanisms of Propagation of Intercellular Calcium Waves in Arterial Smooth Muscle Cells

Jean-Jacques Meister, Jean-Louis Bény, Michèle Koenigsberger, Dominique Seppey

In rat mesenteric arteries, smooth muscle cells exhibit intercellular calcium waves in response to local phenylephrine stimulation. These waves have a velocity of similar to 20 cells/s and a range of similar to 80 cells. We analyze these waves in a theoret ...

Complexity and performance in simple neuron models

Wulfram Gerstner, Richard Naud, Skander Mensi

The ability of simple mathematical models to predict the activity of single neurons is important for computational neuroscience. In neurons, stimulated by a time-dependent current or conductance, we want to predict precisely the timing of spikes and the su ...

Membrane potential dynamics of GABAergic neurons in the barrel cortex of behaving mice

Carl Petersen, Michael Avermann, Ferenc Mátyás

Computations in cortical circuits are mediated by synaptic interactions between excitatory and inhibitory neurons, and yet we know little about their activity in awake animals. Here, through single and dual whole-cell recordings combined with two-photon mi ...

Optimizing Local Capture of Atrial Fibrillation by Rapid Pacing: Study of the Influence of Tissue Dynamics

Jean-Marc Vesin, Laurent Renaud Uldry, Vincent Jacquemet, Lukas Kappenberger

While successful termination by pacing of organized atrial tachycardias has been observed in patients, rapid pacing of AF can induce a local capture of the atrial tissue but in general no termination. The purpose of this study was to perform a systematic e ...
