Portrait Gerd Kempermann


  • Why is activity good for the brain?
  • How do changes on a cellular level contribute to adaptation processes that allow the brain (and with it its owner) to age successfully?
  • How can we train our brains to better withstand disease and age-related impairment? What can we do, if impairment and disease are already there?

Against common wisdom even the adult and aging brain can generate new neurons from a population of resident stem cells but it does so only in two privileged regions and on a minute scale. This process, adult neurogenesis, however, is tightly linked to brain function in the hippocampus, a brain area centrally involved in learning and memory processes. This connection makes it likely that adult neurogenesis serves a fundamental function for higher cognitive functions. In addition, both physical and cognitive activity regulate adult neurogenesis. Thereby, training and activity very directly act upon stem cells in the brain and induce them to produce neurons that serve a function in learning and memory.

Future Projects and Goals

The Genomics of Regeneration group at the German Center for Neurodegenerative Diseases (DZNE) Dresden and the CRTD is interested in adult neurogenesis and covers three research areas.

We precisely examine the activity-dependent control of adult neurogenesis and of other precursor cell populations in the brain and try to understand how the stem cells receive and translate the signal that new neurons are needed. To reach this aim we study adult neurogenesis in the mouse brain and use environmental enrichment (as a cognitive stimulus) and voluntary physical activity as stimuli to increase adult neurogenesis. Our most recent line of projects deals with the neurobiology of individuality. How does activity-dependent plasticity individualize the brain? We hypothesize that this individualized potential is a key determinant of resilience towards neurodegeneration and the building of reserves in cognitive aging.

We investigate how the activity-dependent regulation of adult neurogenesis functions on a molecular level. Here we are less interested in the contribution of individual genes (as important as these obviously are) but in the behavior of large genetic networks – hence the emphasis on genomics rather than genetics in our group name. We use large-scale gene expression studies and phenotypic analyses in defined sets of mouse strains (so-called genetic reference populations) as well as sophisticated biomathematical tools to learn about how high-dimensional gene-gene interactions respond to the activity-dependent stimulus and affect the stem cells and developing new neurons. We also mimic these conditions on isolated precursor cells in cell culture experiments. Finally, we are interested in how neurodegenerative disease affects the brain at the stem cell level.

We study how exactly new neurons in the adult brain might contribute to brain function and how a failure of adult neurogenesis might contribute to brain disease or cognitive impairment in aging. We closely collaborate with psychiatrists, neurologists, and psychologists to root our mouse research tightly in knowledge from the human situation. The main disorders we are focusing on are depression and age-related cognitive impairment and dementias.
