About us

 

The research in the Kann laboratory has two scientific focuses:

 

1. The human brain has a relatively high energy demand and is very sensitive to shortage of oxygen and glucose. We investigate the neuronal energy metabolism and the functions of mitochondria, in particular during synchronized neuronal network activities that underlie higher brain functions, such as perception and memory, under physiological and pathophysiological conditions.

 

2. The human brain possesses innate immune cells, so-called microglial cells (resident macrophages). Microglia become activated, for example, during injury and infection. We investigate the impact of microglia at different activation stages on neuronal network activities and neurodegeneration.

 

Our basic research provides insights into pathophysiological mechanisms that might have a role in brain diseases, such as multiple sclerosis and Alzheimer's disease.
