There are many types of memory, but fundamentally, humans remember in two ways. Declarative memory consists of ordinary recollections consciously summoned from the brain. It is dependent on the medial temporal lobe (MTL), which in turn contains key cognitive structures, including the hippocampus and entorhinal cortex. Declarative memory allows us to explicitly recall or recognize...
