Understanding and Treating Memory

remote memory

Our laboratory is interested in unraveling the molecular, cellular and systems mechanisms responsible for remote memory storage in neocortcal networks.

Although there is very little known about how our oldest memories are stored, our laboratory has already demonstrated the involvement of specific molecular processes and physiological mechanisms in this fascinating phase of memory.

We have a long standing collaboration with the laboratories of Joshua Trachtenberg, Kevin Fox, and Michael Stryker on molecular and cellular mechanisms involved in cortical plasticity. Our results suggest that these mechanisms have a central role in remote memory.
