Jordan Poppenk, PhD, Princeton University, will give a talk titled "Encoding-retrieval interactions in human memory."
While questions about human memory are often framed in terms of separate information encoding, storage, and retrieval stages, memory operations in the world are rarely so pure: for example, encoding is influenced by retrieval of older memories, and retrieval events are themselves encoded. In the current talk, Poppenk will address these interactions using a computational cognitive neuroimaging approach. On one level of analysis, Poppenk uses neural signatures of retrieval to examine its roles in cognition: how does retrieval influence construction of new memories, and alter retrieved ones? On another level, Poppenk probes the hippocampal substrates of retrieval, using neuroanatomy to derive and test predictions about structure-function relationships along the structure's long axis. Future directions are also discussed.
