Brain-wide microstrokes affect the stability of memo ry circuits in the hippocampus

https://rdp.sfb274.de/ (Research Data Platform) https://gepris.dfg.de/gepris/projekt/408885537 (DFG Gepris entry) The central nervous system (CNS) is a terminally differentiated tissue, where any insult carries a heightened risk - yet the tissue response to these insults is variable and can range from irreversible destruction to almost complete recovery. The rules that instruct these divergent outcomes are still unknown. The aim of this CRC is therefore to understand the biology of the multicellular ...

Strokes destroy excitatory inputs – not only in the stroke area, but also in remote regions such as the hippocampus, which may lead to disorganized GABAergic activity and cause cognitive decline. We propose here to identify and modulate checkpoints of GABAergic population dynamics shaping microcircuits of excitatory pyramidal neurons in the hippocampus. We aim at enhancing functional and structural rewiring processes by systematically modulating GABAergic interneuron activity and thus defining ...
