Major Research Interests
The contact sites between two neurons, called ?synapses?, are the most fundamental information processing units in the brain. The minute size of synapses creates an inherent difficulty for conventional imaging but makes them an ideal target for STED microscopy. Because even a single neuron establishes a huge amount of synapses, they are best observed in undamaged, intact tissue, such as in brain slices or even better in living animals. In recent years we have used STED microscopy to image dendritic spines in living tissue and in the cortex of living mice. More specifically, we have been examining the structural dynamics of dendritic spines, which are thought to form the basis of memory in the brain. In our research group we will continue to study structural changes and morphological details using STED microscopy mainly with focus on the living and intact brain.
