Populærvitenskapelig sammendrag av avhandlingen/ Summary of the thesis
The brain is highly plastic and can modify its connections throughout the lifetime. Connections between neurons appear and disappear, in order to strengthen important memories while irrelevant memories fade away.In this thesis, I present three reports about factors that contribute to plasticity in the hippocampus using rats.
The first project utilized an anatomical tracing approach to investigate the development of connections from the hippocampus and parahippocampus to the retrosplenial cortex. We found that connections were present at birth, indicating that these connections are experience-independent. Paper 2 and 3 investigated the plasticity in the adult hippocampus. I used viruses to overexpress growth hormone (GH) in the hippocampus and found that the GH enhanced the hippocampal memory and changed the neural activity.
Revealing the factors affecting hippocampal plasticity is important to understand the mechanisms behind memory deficiency.
