The hippocampus and long-term memory
Cognitive Neuroscience, 2022This special issue of Cognitive Neuroscience focuses on the roles of the hippocampus during long-term memory. A discussion paper by Tallman, Clark, and Smith (this issue) found that functional connectivity of the hippocampus with the parahippocampal cortex and fusiform gyrus decreased with memory age, providing support for systems consolidation ...

Long-Term Potentiation and Memory
1989Long-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, 2010Despite 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, 1999Recent 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 ...

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, 1997Memory 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 ...

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 ...

CREB and the formation of long-term memory
Current Opinion in Neurobiology, 1996Cyclic AMP response element binding protein (CREB)-responsive transcription plays a central role in the formation of long-term memory in Drosophila, Aplysia and mice. Agents that disrupt the activity of CREB specifically block the formation of long-term memory, whereas agents that increase the amount or activity of the transcription factor accelerate ...

DNA Methylation in Long-Term Memory
PhysiologyUnderstanding the neural mechanisms of memory has been one of the key questions in biology. Long-term memory, specifically, allows one to travel mentally without constraints of time and space. A long-term memory must have gone through a series of temporal processes: encoding, consolidation, storage, and retrieval.

A Unified Long-Term Memory System⋆
1999Memory-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.
