Research

Interplay between Stability and Plasticity in Hippocampal Circuits

Since the early time of Descartes at the turn of the 17th century, scientists and philosophers have been searching for the physical correlate of thoughts and memories. During the past 60 years, mounting evidence indicates that experience-dependent changes in synaptic transmission and neuronal wiring, phenomena collectively termed synaptic plasticity, underlie the cellular basis of neural computation, learning and memory. Hebbian-like plasticity is crucial for refinement of neural circuits and information storage, however, alone it is unlikely to account for the stable functioning of neural networks. Both, stability and plasticity are hallmarks of brain function that enable adaptations to unpredictable and dynamic environment, experience and learning. Coping with constantly changing environments, neural circuits need to spend a considerable amount of their available energy to maintain homeostasis and to minimize the effects of stochastic events. Destabilization of hippocampal and cortical circuits has been widely documented in neurodegenerative disorders, e.g. Alzheimer’s disease, the most frequent form of late-life dementia. However, the key mechanisms that underlie stability of activity patterns in central mammalian neural circuits are largely unknown. Furthermore, how disruption of these mechanisms affects the progression of Alzheimer’s disease remains an enigma.

Our research focuses on two key questions:

  1. How do individual neurons and neural networks achieve an ongoing balance between stability and plasticity under a constantly changing environment?
  2. What are the mechanisms driving synaptic and network dysfunctions in Alzheimer’s disease?
