The usefulness of"memory" is being questioned as a concept for explaining the facts of remembering. The brain is an extensive and elaborate switching system for organizing sensory inputs from environmental situations and for generating appropriate and properly timed responses to them. The learning of knowledge consists of learning a…

The National Institute of Education takes a fundamental approach to the problems it is addressing. This implies the creation of an intellectual framework for the problem areas, which can be used to systematize existing knowledge and research approaches and suggest promising new directions for research and development. Neural mechanisms of learning…

There are numerous and complex events taking place during brain maturation that provide the biologic underpinnings of learning and behavior. (MM)

Reviews a study which sought to obtain a quantitative metabolic map of the neurons mediating a specific memory. Research results support notions of cooperative processes in which nonrandom behavior of high ensembles of neural elements mediates the integration and processing of information and the retrieval of memory.

Subjects between the ages of 50 and 86 years were given portions of the Halstead-Reitan Neuropsychological Test Battery, the Wechsler Memory Scale, and the Wechsler Adult Intelligence Scale. Younger subjects performed significantly better than older subjects on 10 of the 18 neuropsychological measures used. (Author/BEF)

The role of the hippocampus in memory function is discussed. Work with rats, monkeys, and humans largely agrees concerning its function and structure. The hippocampus is essential for a type of memory designated "declarative," the ability to remember that a visual object was presented in a particular context. (SLD)

In a previous functional magnetic resonance imaging (fMRI) study we demonstrated an involvement of the medial temporal lobe (MTL) during an implicit learning task. We concluded that the MTL was engaged because of the complex contingencies that were implicitly learned. In addition, the basal ganglia demonstrated effects of a paralleled…

Recent evidence suggests a close functional relationship between memory formation in the hippocampus and dopaminergic neuromodulation originating in the ventral tegmental area and medial substantia nigra of the midbrain. Here we report midbrain activation in two functional MRI studies of visual memory in healthy young adults. In the first study,…

Shows how the spatial elements in reading matter contribute to its meaning. The importance of breaking up any complicated passage into fragments which are easy to understand is emphasized. (Author/RK)

A discussion of the Selcuk Network, a scheme which achieves response routing on the basis of strictly local information, pursuant to the broadcast of a general message, it has applicability to content-based addressing and to computor-to-computer communication nets. (Author)

The [delta] subunit of the GABA[subscript [Alpha]] receptor (GABA[subscript [Alpha]]R) is highly expressed in the dentate gyrus of the hippocampus. Genetic deletion of this subunit reduces synaptic and extrasynaptic inhibition and decreases sensitivity to neurosteroids. This paper examines the effect of these changes on hippocampus-dependent trace…

Despite a long history and considerable study, leadership remains a notoriously perplexing and enigmatic phenomenon. Although the "new leadership" perspective has revived convictions and general interest in leadership studies, conceptual and methodological problems nevertheless remain a feature of the research and theory-building terrain, and some…

Socioeconomic status (SES) is associated with childhood cognitive achievement. In previous research we found that this association shows neural specificity; specifically we found that groups of low and middle SES children differed disproportionately in perisylvian/language and prefrontal/executive abilities relative to other neurocognitive…

Research identifies two interrelated memories--one that retains facts and symbols and one that retains motor and problem-solving skills. These and other findings challenge educators to determine what students should memorize, to help them move from random memorization to creating useful concepts, and to teach students to use memory in problem…
