Long-Term Potentiation and Memory

1989
Long-term potentiation is an enduring alteration in monosynaptic efficacy seen in a variety of synaptic junctions in the mammalian central nervous system. First discovered in 1973, LTP has been extensively studied both in terms of its underlying mechanism of action and more recently in terms of its behavioral significance.

Long-term memory in brain magnetite

Medical Hypotheses, 2010
Despite theoretical and experimental efforts to model neuronal networks, the origin of cerebral cognitive functions and memory formation are still unknown. Recently, we have proposed that in addition to chemical and electrical signals, the cellular components of the neocortex (especially neurons and astrocytes) may communicate with each other through ...

Long-term memory in Alzheimer’s disease

Current Opinion in Neurobiology, 1999
Recent findings have further characterized the neural and psychological bases of long-term memory failure in Alzheimer's disease. Convergent volumetric neuroimaging studies indicate that loss of episodic memory is specifically related to early-stage limbic-diencephalic pathology, and that non-mnemonic impairment is specifically related to later-stage ...

Long-Term Memory

1993
It is clear that analogy cannot work effectively without recourse to an effective method of storing patterns. However, I suggest that an even stronger statement holds: the nature of analogy actually dictates a particular type of memory structure. The only way analogy can work effectively is if it is coupled with a memory that is specifically structured

Functional Anatomy of Long-Term Memory

Journal of Clinical Neurophysiology, 1997
Memory in the brain is organized into multiple memory systems that perform different memory functions and have different neurologic substrates. Declarative memory involves conscious memory for facts and events. The medial temporal lobe and structures in the diencephalon are essential in the establishment of new declarative memories, and these memory ...

Long-Term Memory

2017
What is the most powerful reason why we refuse to watch a movie? The answer is not the genre, the plot, the effects, nor whether it features Tom Cruise. The overwhelming reason why we refuse to watch a movie is that we've seen it already. A study of 21,000 viewings of 150 movies among 500 Penn State students revealed that 65% of movies first seen in a ...

A Unified Long-Term Memory System⋆

1999
Memory-based reasoning systems are a class of reasoners that derive solutions to new problems based on past experiences. Such reasoners use a long-term memory (LTM) to act as a knowledge base of these past experiences, which may be represented by such things as specific events (i.e. cases), plans, scripts, etc.

Evolutionary hypothesis of long-term memory

Medical Hypotheses, 2000
Learning is concerned with the operations that place a relatively stable behavioral potential in memory. From this point of view, memory may be defined as the storage of learned behavioral potential over time. Memory may also be defined as a persistent change in the CNS brought about by environmental input and by the activity of the organism (including

Brain systems and long-term memory

Behavioral and Neural Biology, 1983
This paper focuses mainly on those findings derived from lesion studies on the rat which help to identify ensembles of neural structures concerned with the expression of previously learned responses. At the outset, the use of the lesion method in the search for those neurological circuits underlying memory is defended. This is followed by an evaluation
