In Greek, “en” means within and “gramma” means a letter or a record. So engram means that something is recorded within, and that made sense to the German researcher Richard Semon when he was studying the formation of memory in the early 20th century. He proposed a term, engram, to describe how a memory could be encoded upon the brain and retrieved later.

Close your eyes. Try to remember your last birthday. Can you remember the taste of the cake and the colors of your wrapped presents? There’s a theory that memories are encoded through physical changes in your neurons, and these changes are called engrams. That almost-tangible sense memory that comes along when you bring up thoughts of a moment in the past is thanks to engrams.
