Homeostatic synaptic plasticity
Neurons adapt their structural and functional properties in response to changes in network activity. However, despite these changes stability of neuronal networks must be assured. We study the cellular and molecular mechanisms, which control the ability of neurons to maintain stability, in order to better understand (and eventually augment) the ‘homeostatic resilience’ of neural networks under pathological conditions.
