Engram: meaning, definitions and examples

Etymology

• The term 'engram' comes from the Greek word 'engraphein,' meaning 'to write in' or 'to engrave.'
• The concept was introduced in the late 19th century by psychologist Richard Semon, who investigated how memories are retained.

Psychology

• Engrams are thought to be the physical changes in the brain that occur when a memory is formed.
• Studies suggest that engrams can be strengthened or weakened over time, affecting how easily we recall certain memories.

Neuroscience

• Recent research indicates that specific neurons in the brain may encode different aspects of our memories, forming unique engrams.
• Techniques like optogenetics allow scientists to activate or silence engrams in the brains of animals, helping to explore memory function.

Pop Culture

• Movies and books often depict memory manipulation, playing on the idea of altering engrams as a way to change past experiences.
• Video games sometimes feature characters who can access or change their engrams to alter gameplay or story outcomes.

Philosophy

• The concept raises questions about the nature of memory and personal identity, challenging how we understand ourselves over time.
• Philosophers ponder whether memories stored as engrams are reliable sources of truth or merely subjective experiences.
