engram
Neural memory imprint
An engram is a hypothetical physical trace that a memory leaves in the brain—the neural substrate of a stored experience.
The term belongs to neuroscience and psychology, where researchers debate whether engrams can be precisely located or are distributed across brain regions.
Scientists identified engrams associated with fear memories in mice.
The concept also appears in Scientology with a different, specialized meaning.
