Molecular biology of long term memory storage: Initiation and maintenance of synaptic growth; Examination of features shared in simple forms of learning and memory in the Aplysia nervous system and in the mammalian hippocampus.
We combine behavioral, cellular, and molecular biological approaches to delineate the changes that underlie simple forms of learning and memory in invertebrates and vertebrates. In invertebrates the focus of our research is on the gill-withdrawal reflex of Aplysia. We study three elementary forms of learning: habituation, sensitization, and classical conditioning. Recently we have reconstituted critical components of this learning in dissociated cell culture, and we now use the reconstituted system to examine the molecular mechanisms which contribute to short- and long-term memory.
In vertebrates we use genetically modified mice to examine the mechanisms of long-term potentiation in the mammalian hippocampus and its relation to spacial memory and maintenance.
