Neuroscientist Explores How Memory and Imagination Intertwine in the Brain

Philosopher Felipe De Brigard, a 2026 MacArthur Fellowship recipient, studies how the brain reconstructs memories by filling in gaps with imagination rather than storing experiences like digital recordings. His research demonstrates that the mental processes underlying memory retrieval overlap significantly with those used to imagine hypothetical futures and alternative pasts. De Brigard's work highlights the inherent fallibility of human memory and the creative role imagination plays in shaping how we experience and recall our lives.

De Brigard's research builds on foundational work by psychologist Endel Tulving, whose studies in the 1980s revealed that brain regions responsible for recalling past experiences also activate when envisioning future scenarios. A particularly illuminating case involved a patient with hippocampal damage who couldn't remember past events or imagine personal futures, suggesting these cognitive functions rely on overlapping neural systems. De Brigard's investigations extend this framework by examining how imagination actively reconstructs memories by filling gaps with plausible details, challenging the intuitive notion that memories function as accurate recordings.
