engram

[ˈɛnɡræm ]

Definition

Context #1 | Noun

memory theory

An engram is a theoretical construct used in the field of psychology and neuroscience, referring to the physical representation of memory in the brain. It is proposed as a lasting change in the brain's structure and function that results from experience, potentially allowing for the storage and retrieval of memories. The concept was first introduced by Richard Semon, who emphasized that engrams represent a network of neurons that become associated together through experience. This notion has profound implications for understanding learning, memory retention, and the neural mechanisms underlying them.

Synonyms

memory imprint, memory trace.

Examples of usage

  • The engram is formed through repeated experiences.
  • Researchers are studying how engrams can aid in memory recovery.
  • Certain brain regions are believed to be responsible for engram creation.

Interesting Facts

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.

Origin of 'engram'

Main points about word origin

  • 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.

The word 'engram' was coined by the German zoologist Richard Semon in his works during the early 20th century. Semon introduced the term to describe the hypothetical physical representation of memory that persists in the brain after an experience has occurred. His work was influenced by the prevailing ideas of the time regarding the nature of memory and learning, as well as advancements in neuroscience. The term derives from the Greek word 'en-' meaning 'in, within' and 'gram' meaning 'something written' or 'to draw.' Originally, Semon's theories were met with skepticism, but they gradually gained traction as researchers sought to understand the biological underpinnings of memory. Over the decades, the study of engrams has evolved, intersecting with various fields such as psychology, neurobiology, and cognitive science, leading to a wealth of research exploring how memories are formed, stored, and retrieved in the brain.
