An internationally recognized pioneer in research on brain-based neural networks, the molecular basis of memory, and degenerative brain disorders, he has authored hundreds of scientific articles as well as several books, including Memory Traces in the Brain by Cambridge University Press, and the popular book Memory's Voice by Harper Collins.
He marked out our Memorial sites, or more exactly the places of our Memory traces, whose symbolic, affective, and functional meanings, and whose known, evolving, and living significations, far outstrip the immobile purport of traditional monuments that we catalog in Western Memory.
In this respect, one of the most prominent theories within this area is known as Standard Model of Systems Consolidation (SMSC) which holds that initial memory traces are encoded in both the hippocampus and cortex.
In this task, the behavioral performance can be efficiently measured in a single trial session and, given that the underlying memory traces are long-lasting, it allows researchers to perform a characterization of possible changes in the expression levels of potential transcription factors involved in memory acquisition and in the recall phases.
In citing Karl Lashley's celebrated failure to find localized memory traces in the brain, Matlock is going back to work conducted in the 1930s, when the field of psychology was in its infancy.
The better your physical condition, the better your chances of creating strong and lasting memory traces. To sharpen your powers of retention and recall:
The first makes the most sense: the weakening of the synapses in the networks that form the memory traces. The second, however, is counterintuitive: It comes from the formation of new neurons from stem cells.
Since the hippocampus is known to contain large iron particles, it was felt that perhaps the hippocampus is acting as a large iron-core electromagnet responsible for encoding and decoding memory traces. Much like the recording of a videotape using magnetized electrical fields to place electrons on the surface of the tape, the hippocampus seems to be coding areas within the neocortex.
The engrams, or memory traces, of this particular experience are known to be located in the dentate gyrus of the hippocampus, a key brain area for memory processing.

Collingwood's The Idea of History (1956), Lowenthal affirms that the past does not exist and that, in spite of relying on memory traces, it can never be relived.
