Research Focus

We investigate signal processing from single neurons to networks.

In particular, we would like to understand how neurons are optimized for their computational task. Therefore, we investigate the relationship between intrinsic neuronal properties and the signaling mechanisms shaped by them, as well as their relevance for network behavior. The aim is to link the molecular level of ion channels to characteristics of neuronal firing, focusing on topics like spike-timing reliability, cell-intrinsic frequency preference, information transfer, and energy efficiency. To identify computational principles, conductance-based and phenomenological models are used in combination with data evaluation techniques. We closely cooperate with experimentalists in order to test theoretical predictions.

We are part of the Institute for Theoretical Biology at Humboldt-Universität zu Berlin and the Bernstein Center for Computational Neuroscience Berlin.


  • Yet another Ph.D. Defense: This time it was Fred's turn to complete his PhD on the temperature dependence in an insect auditory system. Well done, Dr. Roemschied! (September 2016). Fred now moves on to the Murthy lab at Princeton University.
  • Bernstein Workshop: Susanne and Tatjana Tchumatchenko organize the workshop "Signatures of efficient coding" at the Bernstein Conference 2016 in Berlin (September 20th 2016).
  • Ph.D. Defense: Eric successfully defended his thesis on the analysis of phase precession in the entorhinal cortex. Great job, Dr. Reifenstein! (July 2016).
