Short‐term and long‐term memory in single cells
The FASEB Journal, 1991Many approaches have been used to study short‐ and long‐term memory. Bacteria detect chemical gradients using a memory obtained by the combination of a fast excitation process and a slow adaptation process. This model system, which has the advantages of extensive genetic and biochemical information, shows no features of long‐term ...

The long and the short of long–term memory—a molecular framework
Nature, 1986A single learning event initiates several memory processes with different time courses of retention. While short term memory involves covalent modification of pre-existing proteins, the finding that long-term memory requires the expression, during learning, of additional genes, makes it possible to analyse in molecular terms the induction and retention

Short-Term Memory to Long-Term Memory Transition in a Nanoscale Memristor
ACS Nano, 2011"Memory" is an essential building block in learning and decision-making in biological systems. Unlike modern semiconductor memory devices, needless to say, human memory is by no means eternal. Yet, forgetfulness is not always a disadvantage since it releases memory storage for more important or more frequently accessed pieces of information and is ...

Hardware aspects of Long Short Term Memory
2018 25th IEEE International Conference on Electronics, Circuits and Systems (ICECS), 2018This paper focuses on hardware implementation aspects of a Long-Short Term Memory (LSTM) network application. Initially, certain piecewise approximations to activation functions $\sigma$ and tanh are proposed. Next a training procedure is introduced which exploits proposed piecewise approximations.

Memory dysfunction is extremely complex, due to the variety of symptoms that occur, changes over time, and perhaps a dependency of symptoms upon location of lesion. In this chapter, adaptive problems created by memory deficits will be emphasized, i.e., frequently observed syndromes and symptoms, and some descriptive concepts that will be useful in ...

As discussed in the previous chapter, an important benefit of recurrent neural networks is their ability to use contextual information when mapping between input and output sequences. Unfortunately, for standard RNN architectures, the range of context that can be in practice accessed is quite limited.

Two circuits to convert short-term memory into long-term memory
Medical Hypotheses, 1997According to a brain model, encoding synapses record presynaptic axonal 'on-off' patterns as memory, and modulating synapses convert short-term memory into long-term memory by helping encoding synapses develop long-term potentiation and depression. Sensory organs conduct sounds and images as series of axonal 'on-off' patterns to encoding synapses of ...

A statistical theory of short and long term memory
Behavioral Biology, 1975We present a theory of short, intermediate and long term memory of a neural network incorporating the known statistical nature of chemical transmission at the synapses. Correlated pre- and post-synaptic facilitation (related to Hebb's Hypothesis) on three time scales are crucial to the model.

Distributed Memory for Both Short and Long Term
Neurobiology of Learning and Memory, 1998Neuropsychology points to the wide distribution of cortical memory networks. Electrophysiology and neuroimaging indicate that working memory, like long-term memory, is a widely distributed function, largely neocortical. Most of the evidence available from those three methodologies suggests that both working memory and long-term memory share the same ...
