Engram ( Greek έν - staying in any state or action + Greek. Γράμμα - all written, entry) is a term coined by the German zoologist and biologist Richard Zemon at the beginning of the XX century. In the theory of mnemism, an engram is a physical habit or memory trace on the protoplasm [1] of an organism left by repeated exposure to an irritant.

Etymology
Literally from Greek, the word "engram" means "internal record." With this word, the ancient Greeks designated wax tablets to record the meanings of various signs. [2]
General Information
Incentives or irritants leave clear traces (engrams) on the protoplasm of an animal or plant. When the action of this stimulus is regularly repeated, it creates a habit that remains in the protoplasm after the cessation of the action of the stimulus.
The hypothetical trace of memory. According to the content, there are two types of engrams: images (display of the static structure of an object) and an action model (program).
According to hierarchical levels of complexity, primary engrams, associations of engrams (two interrelated engrams) and associative networks of engrams are distinguished.
