Fragile X and Turner syndromes are two X-chromosome-related disorders associated with executive function and visual spatial deficits. In the present study, we used ocular motor paradigms to examine evidence that disruption to different neurological pathways underlies these deficits. We tested 17 females with fragile X, 19 females with Turner…

This study looks at whether conventional and anomalous metaphors are processed in different locations in the brain while being read when compared with a literal condition in Mandarin Chinese. We find that conventional metaphors differ from the literal condition with a slight amount of increased activation in the right inferior temporal gyrus. In…

We investigated processing of metaphoric sentences using event-related functional magnetic resonance imaging (fMRI). Seventeen healthy subjects (6 female, 11 male) read 60 novel short German sentence pairs with either metaphoric or literal meaning and performed two different tasks: judging the metaphoric content and judging whether the sentence…

Neurofibromatosis, type 1 (NF-1) is a common genetic disorder affecting 1 in 3,500-4,000 individuals in the world. Mutations of the NF-1 gene produce a myriad of physical, medical, and psychological manifestations. Although there is a very high degree of variability in the manifestations between individuals with NF-1, the majority of children and…

Among conclusions of this review of findings regarding contemporary neuropsychology and cerebral hemisphere specialization as related to learning disabilities are: (1) differential specialization occurs very early; (2) anomalous hemispheric specialization is not necessarily associated with cognitive deficit; and (3) left- and right-hemisphere…

The ontological problem is "what exists?" The answer regarding the part of consciousness which is related to left hemisphere is that only individual discrete objects exist; objects are regarded one at a time. The answer regarding the part of consciousness which is related to right hemisphere is only comprehensive entities exist; each…

The brain's capability to apprehend complex information at multiple levels is ignored when teaching is limited to rote or "symbol-specific" learning. Educators should be concerned with increasing neurological networks or "maps" representing richness of content, instead of teaching isolated, segmented facts along well-worn…

In an effort to explore S. Orton's "intergrading" hypothesis, six developmental dyslexics (ages 16 to 47) and four good readers were tested on measures of interhemispheric coordination. Dyslexics showed reduced laterality bias and longer response latencies to bihemifield stimuli. (Author/DB)

Continuing dramatic developments in the ability of neuroscientists to peer inside the brain to discover its incredible intricacy places awesome responsibility on all educators to "do the right thing" for their students. Here, the authors offer readers powerful brain-compatible and research-based teaching and learning strategies based on how the…

Analysis of use of positron emission tomographic measurements of resting-state regional cerebral blood flow in 29 men, 10 of whom stuttered, did not support the idea that developmental stuttering is associated with abnormalities of blood flow at rest. Findings did suggest an essentially normal functional brain terrain with a small number of minor…

Quantitative EEG magnitude data were obtained from children with and without attention deficit disorder (ADD). The data suggest that the right fronto-centro-temporal region is not as "cognitively activated" relative to the left hemisphere in those children with ADD. Neurotherapy training of the right frontal and central regions in ADD…

Examines research that suggests there are physiological differences between male and female brains. Considers the implications for adult education. (SK)

Presents data from a patient with a progressive fluent aphasia, who exhibited a severe verbal impairment but a relatively preserved access to knowledge from pictures. Argues for a distributed, multi-modality system for semantic memory in which information is stored in different brain regions and in different representational formats. (Author/VWL)

Two studies examined the ability to assign thematic roles and to coindex referentially dependent noun phrases in closed head injured adults (N=20), adult stroke patients (N=20), and normal adults (N=20). Results suggested that syntactic comprehension disturbances are similar following left cerebral hemisphere infarction and closed head injury.…

The mechanisms of both language-based and non-language-based learning disabilities are presented within the framework of central nervous system development and the compromises to that development that arise from genetic, hormonal, antibody, medication, and postnatal compromises. Also reviewed is the need for a taxonomy of learning disabilities.…
