Location of S-T Memory

In addition, investigate the fascinating discussion of "H.M." in Long-Term Memory, the man some researchers claim contributed the most to our understanding of memory.

Memory & the Hippocampus

Rita Carter explains in her new book The Human Brain that “memories are stored in fragments throughout the brain and are distributed throughout the brain. One way to envisage the pattern of memories in the brain is as a complex web, in which the threads symbolize the various elements of a memory that joins at the nodes, or intersection points, to form a whole, rounded memory of an object, person, or event.”

One benefit of such a distributed storage system is that it makes long-term memories more or less indestructible because if one part of an experience is lost, many others will remain.

If they were held in a single brain area, damage to that place would eradicate the memory completely. As it is, brain trauma and degeneration may nibble away at memories but rarely destroy them entirely. You may lose a person’s name, for example, but not the memory of their face.

Carter explains that “declarative memories are laid down and accessed by the hippocampus but are stored throughout the brain. Each element of a memory is encoded in the same part of the brain that originally created that fragment. When you recall the experience, you recreate it in essence by reactivating the neural pattern generated during the original experience that was encoded to memory. Once a memory is sparked off, the hippocampus triggers various aspects of it in unison and different brain areas recall a variety of memories.”

Take, for example, the memory of a dog or cat you once owned. Your recall of his color is created by the color area of the visual cortex; the motor area of your brain reconstructs the recollection of walking the dog; his name is stored in the language area, and so on.



There are two fundamental phenomena regarding memory that all educators should be quite attentive to as they directly affect memory and how well students remember information after initially presented.

By understanding these two essential factors affecting working memory detailed in November 2017 Ed Tip, educators will be able to drastically improve students’ retention of new information.
