Up- down state switching in a conductance- based cortical model — Hong-Viet Ngo, •Arne Weigenand, and Jens Christian Claussen — Institut für Neuro- und Bioinformatik, Universität zu Lübeck

In recent experiment [1] investigated the on- and off switching of bursting activity in ferret brain slices. This experiment is seen as a paradigmatic system towards the understanding of the emergence of cortical slow waves. The basic dynamics can be modeled by a simplified discretized integrate-and-fire model including inhibitory currents [2]. Here we use a conductance-based model to reproduce the spike-burst dynamics and the triggering of on-states as obeserved in [1].
