About this listen

This episode explores one of neuroscience’s deepest mysteries: how the brain stores and retrieves memories. Beyond synaptic plasticity, research shows memory is a dynamic and reconstructive process, shaped by sleep, consolidation, and constant reconsolidation.


Scientists search for the physical memory trace—the engram—across molecular, structural, and genetic levels. Despite breakthroughs in brain mapping and optogenetics, the code that turns neural activity into lived experience remains unresolved.
