In 1953, a young man, later became known as a patient HM, underwent an experimental surgery to bilaterally remove hippocampi as treatment of the intractable epilepsy. Fortunately, HM's epilepsy became controllable but now he had another problem. While he could still recall his old memories, he could not memorize anything new. From the studies on the symptoms HM exhibited, we now know that hippocampus is the site where a memory is initially formed but not stored for long-term. But we still do not know the detailed mechanism by which memory is encoded in hippocampus, transferred to the rest of the brain, and recalled. This is one of oldest and most profound questions left for mankind.
In our laboratory, we approach this question from multiple levels of studies from molecules to animal behavior:
- Protein Trafficking and Long-term Potentiation
- Liquid-liquid phase separation and synaptic plasticity
- Molecular Mechanisms of Structural Plasticity of Dendritic Spines
- Dynamic Behavior of Cellular Memory Engram
