Our research focuses on processing dynamics within the brain. Specifically, we investigate its capacities for plastic reorganization (i.e., synaptic re-wiring and learning). Using optical imaging techniques combined with sophisticated data analysis and modeling, we aim at deciphering the brain‘s computational strategies that finally lead to perception and behavior.
Optical imaging is unique in its capability of capturing the activity of millions of neurons at once using light. In combination with optogenetics (i.e., light stimulation and recordings of specific target neurons and neuronal subnetworks) our approach provides an access to both theoretical and experimental questions dealing with the highly dynamic activity patterns ob­served across the brain.
