What have hippocampal place cells told us about why my great-grandmother maintained strong memories of her childhood but failed to make to new memories in her old age? When people are young, spatial environments are fully encoded by hippocampal cells and probably eventually become cortical memories, no longer requiring the hippocampus (Squire and Alvarez, 1995). As people age, new spatial environments are encoded more weakly by hippocampal cells, and they are less able to prompt later recall. Hippocampal place cells, thus, provide a clear window for investigating age-related impairments in the formation and retrieval of memories and may serve as a powerful tool for evaluating potential preventive measures.
