It remains unclear which biophysical or biochemical mechanisms underlie or represent an engram. WebMemories for events are thought to be represented in sparse, distributed neuronal ensembles (or engrams). In this article, we review how neurons are chosen to become part of a particular engram, via a process of neuronal allocation.
