New research reveals that memories continue to evolve in the brain
Memory consolidation is the process through which initially fragile memories are transformed into long-term, more stable forms of memory. For decades, neuroscience textbooks have described this process as a gradual transfer of memories from the hippocampus—where memories are first encoded—to the neocortex for permanent storage. Findings by Dr. Sangyoon Ko and colleagues in the Josselyn-Frankland laboratory at The Hospital for Sick Children (SickKids) in Toronto now reveal a far more dynamic process.
