General objective:

Our starting hypothesis is that understanding the operational principles of behaviorally relevant networks requires bridging the gap between the level of elemental neuronal properties (synaptic and intrinsic membrane properties) and that of neural network dynamics. The objective of this project is to provide a comprehensive description of selected neural networks, from constituent neurons and their synaptic connections to the integrated systems level, with the goal to relate the dynamics of neural circuitry to complex functions of the brain and spinal cord. By deciphering the fundamental constructs (anatomical connectivity, cellular and synaptic properties) and modes of operation of identified neuronal assemblies, the aim is then to link these parameters to processes of short- and long-term network plasticity, and ultimately to adaptive CNS function under normal physiological and physiopathological conditions, in the adult and during the course of development. In a search for unifying principles, our focus will range from selected simpler networks of invertebrates to the mammalian brainstem and spinal cord regions controlling motor functions and nociception, to hippocampal and cortical circuits involved in cognition.
