The prefrontal cortex of the primate frontal lobes provides the capacity for judgment which can constantly adapt behavior in order to optimize its outcome. Adjudicating between long-term memory programs and prepotent responses, this capacity reviews all incoming information and provides an interpretation dependent on the events that have just…

In this study, we used a novel cognitive paradigm and event-related functional magnetic resonance imaging (ER-fMRI) to investigate the neural substrates involved in processing three different types of sentences. Participants read either metaphoric ("Some surgeons are butchers"), literal ("Some surgeons are fathers"), or non-meaningful sentences…

This document discusses the problem of teachers who teach primarily to the left hemisphere of the brain, not allowing the right-brain dominant student to expand his creative ability. It presents information about brain structure and function for educators. A glossary of 25 terms is provided with sources of the definitions. Annotations summarizing…

The study compared the performance of schizophrenic patients and normal controls in their ability to direct visual attention. The first experiment compared 12 adult schizophrenic patients with 30 control volunteers in their ability to orient attention in response to peripheral visual cues. The patients were distinguished from controls by a slower…

A 20-item Piagetian-type sorting task was presented to 12 unilaterally brain-injured adult patients and 12 non-injured controls. The left hemisphere brain-injured subjects and the controls showed preferences for the features of shape and texture. In contrast, the right hemisphere brain-injured subjects preferred the feature of size. (Author)

The exploratory study examined patterns of regional cerebral blood flow in a surface and a deep dyslexic during reading. Significant differences in gray matter blood flow were found between subjects and normal controls. Also differences existed between the surface and deep dyslexic in the distribution of cortical perfusion. (Author/DB)

Examined were electroencephalogram (EEG) asymmetries during the presence of discrete facial signs of emotion among 10-month-old infants who were tested in a standard stranger- and mother-approach paradigm that included a brief separation from mother. Data underscore the usefulness of EEG measures of hemispheric activation in differentiating among…

Investigated digit repetition in unilaterally and bilaterally brain-damaged adults to study the hemispheric and neuropsychological factors that underlie performance. Digit repetition was disproportionately depressed in such patients. The data suggest a differential function hypothesis, as well as a unilateral hemispheric hypothesis that underlies…

This paper reviews three studies which examine cognitive processes and brain electrical activity in gifted children. The studies concentrated on mathematically gifted children and/or their sleep patterns. All three studies used the interhemispheric electroencephalogram to examine the gifted child's ability to harness right hemisphere capacities…

This book presents information to help teachers turn research on brain function into practical classroom activities and lessons, offering: brain facts; information on how the brain processes information; tips on maximizing retention; an information processing model that reflects new terminology regarding the memory systems; new research on how the…

Research is reviewed on the relationship between right hemisphere imagery and the development of creativity. The role of nonverbal imagery in the incubation period is discussed. Note: For related information, see EC 120 232-238. (CL)

The 4MAT System honors the distinctive style that each student brings to the classroom, while helping all students grow by mastering the entire cycle of learning styles. The learner makes meaning by moving through a natural cycle--from feeling to reflecting to thinking and, finally, to acting. Teachers need not label learners by style; instead,…

Discusses the brain mechanisms mediating the switching of languages in bilingual subjects. To ascertain the brain mechanisms mediating the control of language switching, switching was examined in a bilingual patient with frontal lobe damage and impaired control processes. (Author/VWL)

Employed a lexical decision task to asses whether left hemisphere damaged (LHD) and right hemisphere damaged (RHD) patients are similarly sensitive to stress patterns in lexical access. Results confirmed that individuals without brain damage are influenced by stress patterns, as indicated by increased lexical decision latencies to incorrectly…

The study assessed how unilateral right hemisphere brain damage (RHD) affects processing of metaphoric aspects of word meaning. RHD stroke patients (N=25) performed similarly to left-brain-damaged and normal subjects in the automatic condition and when provided with processing strategies. Both brain-damaged groups had difficulty developing…
