The present study characterizes the neural correlates of noun and verb imageability and addresses the question of whether components of the neural network supporting word recognition can be separately modified by variations in grammatical class and imageability. We examined the effect of imageability on BOLD signal during single-word comprehension…

The existence of a rostrocaudal gradient of medial temporal lobe (MTL) activation during memory encoding has historically received support from positron emission tomography studies, but less so from functional MRI (FMRI) studies. More recently, FMRI studies have demonstrated that characteristics of the stimuli can affect the location of activation…

Results from studies of retrograde amnesia provide much of the evidence for theories of memory consolidation. Retrograde amnesia gradients are often interpreted as revealing the time needed for the formation of long-term memories. The rapid forgetting observed after many amnestic treatments, including protein synthesis inhibitors, and the parallel…

The Society for Neuroscience (SfN) has more than 37,000 members and constitutes one of the largest single-theme scientific societies in the United States. Although many of its members are engaged in various activities that support their local science education programs, historically the society has not played a major role in shaping the national…

Personality/behavioral characteristics of empirically derived subgroups of learning disabled (LD) children (8-11 years old) were examined. A modified Halstead-Reitan battery was administered to 56 LD Ss. Their parents completed personality/behavioral measures. Ss' scores on 13 neuropsychological measures were cluster analyzed, and three subgroups…

The study compared the Halstead-Reitan (H-R) neuropsychological test profiles of 25 normal, 47 learning disabled (LD) and 20 brain damaged (BD) young adults. Multivariate analyses indicated that the H-R battery could differentiate these groups beyond chance expectancy and that the neuropsychological deficits in LD performance are intermediate in…

Discussed are the role of the sensory integration specialist in diagnosing and treating various disorders of sensory integration. (DB)

The human brain is lateralized, different functions being housed in each hemisphere. Several assumptions which are mistakenly considered fact by researchers include: (1) the left hemisphere is for rational functions, while the right is for intuitive functions; (2) the hemispheres do not interact as well with each other as they should; (3) the use…

The role of pharmacologic agents in the treatment of learning and behavior disorders in children is discussed with respect to the biological basis of these disorders. Illustrative studies dealing with autonomic reactivity and cortical excitability as reflected in the cortical evoked response are presented. The question of the combined effects of…

The author suggests that most research on the early detection of learning disabilities is characterisized by an ineffective and a theoretical method of selecting and validating tasks. An alternative technique is proposed, based on a neurological theory of cognitive processes, whereby task analysis is a first step, with empirical analyses as…

The author, a neurologist, looks at the nature of reading disabilities. He suggests that many reading disabilities are the result of normal constitutional differences and that the term "minimal brain dysfunction" is rarely appropriate and does not help the remediation process. Noted are various theories which relate neurology and reading ability.…

The report presents both a way of looking at perceptual mechanisms in nervous systems in terms of distributed information processing, and a way of creating computer models of parts of nervous systems. The first notion views a nervous system as a collection of interacting parallel-operating computation units, each of which has some part of the…

The postdoctoral fellowship research described in this document was based on three main areas: 1) single subject research, including experiments in learning with a rat and with three stutterers; 2) linguistic research, including basic research methodology and the analysis of morphological and syntactical structures in a language; and 3)…

Authors responded to William Plotkin's article (AA 522 798). They focused on the attempt to explain alpha activity (with and without feedback) as primarily due to oculomotor effects, and the effort to reinterpret previous experiential descriptions of the high alpha state and to substitute a new description based on the data of this study.…
