Cortical rewiring and information storage

Nature, 2004
Current thinking about long-term memory in the cortex is focused on changes in the strengths of connections between neurons. But ongoing structural plasticity in the adult brain, including synapse formation/elimination and remodelling of axons and dendrites, suggests that memory could also depend on learning-induced changes in the cortical 'wiring ...

Modulation and coding for information storage

IEEE Communications Magazine, 1991
Many of the types of modulation codes designed for use in storage devices using magnetic recording are discussed. The codes are intended to minimize the negative effects of intersymbol interference. The channel model is first presented. The peak detection systems used in most commercial disk drives are described, as are the run length-limited (d,k ...

Storage of Information about Time

Perceptual and Motor Skills, 1965
An experiment is described in which the detrimental effects of an auxiliary task on reaction time to periodically presented light stimuli were studied. RT stimuli were presented periodically to one group of Ss throughout the experiment and aperiodically to another.

Information Storage

2010
The success of information transfer from the suppliers depends largely up on the organization of the data to cater for different categories of the users. It calls for quick, competitive and cost effective solutions. To meet the same, hierarchical data representation is introduced in this chapter.

A new approach to information storage

Communications of the ACM, 2013
Disk drives and solid-state drives have long served as the foundation for computer storage, but breakthroughs in molecular and DNA science could revolutionize the field.

Hierarchical storage in information retrieval

Communications of the ACM, 1973
A probabilistic analysis is employed to determine the effect of hierarchical storage organizations on information retrieval operations. The data storage hardware is assumed to consist of n -levels of linearly connected memory hardware with increasing data access times and increasing data storage capabilities.

Photographic storage of AI information

ACM SIGART Bulletin, 1980
As AI projects often use large amounts of storage, the development of high resolution for storing and retrieving data on photo-graphic film may in the future provide a contribution.

Human memory and the storage of information

IEEE Transactions on Information Theory, 1956
The amount of selective information in a message can be increased either by increasing the variety of the symbols from which it is composed or by increasing the length of the message. Psychological experiments indicate that the variety of the symbols is far less important than the length of the message in controlling what human subjects are able to ...

Information Storage and Retrieval Systems

1969
Does the field of information storage and retrieval as presently constituted qualify as a science? If not, can it ever become a science? These two questions continue to be topics of discussion for professionals associated with the field. While it is not difficult to reach an affirmative answer to the initial question, the process of arriving at such an

A note on information organization and storage

Communications of the ACM, 1973
Since the logical structure of a data base can be represented by a tree or graph, it is quite natural for us to view the process of designing a data base as that of constructing a tree or a graph. A general method for constructing such a tree or graph is provided.
