Olfactory cortex as a model for telencephalic processing.
Changes to myriad synapses throughout the brain must be coordinated every time a memory is established, and these synapses must be appropriately reactivated every time it is remembered. Once stored, memories can be recognized (when re-experiencing a learned input) or recalled (e.g., via different input, such as a name evoking memory of a face, or a scene evoking memories of an experience) by many routes. We remember what tables are as well as we remember a specific table, and we recognize objects despite seeing them from quite different angles, different lighting, different settings. Computational simulations of synaptic modifications (e.g., long term potentiation; see related entries in this volume) in distinct brain circuit architectures illustrate how these minute changes can give rise to coherent properties of memory; how analyses of different brain areas yield derivations of disparate memory functions; and how interactions among connected regions give rise to still new operating principles beyond those of their constituents.
