Dynamics of distinct inhibitory interneurons in inhibition stabilised networks

Cortical networks contain a variety of cell types, in particular of GABAergic inhibitory interneurons. Inhibition yields rich and complex dynamics of recurrent networks, but there are many open questions. In particular one might ask, in which ways specific types of inhibitory interneurons are embedded within the brain and how this affects its dynamics.
The talk will introduce some current experimental results on dynamics of parvalbumin- and somatostatin-positive cells in cortical networks and present some exploratory simulations within the framework of inhibition stabilised networks. Specific questions are the change of a single neuron gain by embedding (divisive vs. subtractive), the dynamics of excitatory coupled, inhibition dominated networks and the dynamics of a network containing inhibition of inhibition.
