Research of my group focuses on processing dynamics within the brain. Specifically, we investigate its capacities for plastic reorganization (remodeling, learning) and the underlying state transitions. Us­ing Optical Imaging techniques we show how parameters given in the outer world are represented and processed across large neuronal populations. By additional employment of sophisticated data analysis and modeling we aim at deciphering the brain‘s computational strategies that generate behavior.

Optical imaging is unique in its capability of capturing the activity of millions of neurons at once. In combination with Optogenetics (i.e., light stimulation of specific target neurons and neuronal subnetworks) our approach provides an ideal access to both theoretical and experimental questions dealing with highly dynamic activity patterns ob­served across the brain.
