The cerebral regulation of cardiovascular functioning varies along both a lateral and a longitudinal axis. The parasympathetic and sympathetic nervous systems are lateralized to the left and right cerebral hemispheres, respectively. Further, the frontal lobes are known to be inhibitory in nature, whereas the temporal lobes are excitatory. However,…

The paper explores five major facets of brain functioning in relation to gifted and creative behavior. Emphasis is placed on ways that the educational establishment can cultivate the stages of the creative process for the verbally gifted, the nonverbally gifted, and for young children. (Author/CL)

Concludes that both asymmetry of muscle tonus and somesthetic stimulation contribute to the normally occurring lateral differences in responsiveness, though other factors are involved. (MH)

Used two tapping tasks to determine whether individual infants' right- or left-hand preference for unimanual and bimanual tapping corresponded to their handedness in bimanual manipulation tasks during the second year of life. Also examined whether manual tapping preference occurred before or after the onset of bimanual handedness. (JMB)

The handedness of Leonardo da Vinci is controversial. Although there is little doubt that many of his well-attributed drawings were drawn with the left hand, the hatch marks of the shading going downwards from left to right, it is not clear that he was a natural left-hander, there being some suggestion that he may have become left-handed as the…

Studies have reported a right visual field (RVF) advantage for coherent motion detection by deaf and hearing signers but not non-signers. Yet two studies [Bosworth R. G., & Dobkins, K. R. (2002). Visual field asymmetries for motion processing in deaf and hearing signers. "Brain and Cognition," 49, 170-181; Samar, V. J., & Parasnis, I. (2005).…

Sex differences on language and visuospatial tasks are of great interest, with differences in hemispheric laterality hypothesized to exist between males and females. Some functional imaging studies examining sex differences have shown that males are more left lateralized on language tasks and females are more right lateralized on visuospatial…

Author outlined the characteristics of the right hemisphere of the brain and compared them to those of the left hemisphere. (RK)

Six early treated children with phenylketonuria (PKU) were compared at 9 to 14 years of age on a neuropsychological measure with three groups of children with documented neurological disorders. PKU Ss had overall level of neuropsychological impairment similar to that of brain-damaged groups. PKU Ss did not show consistent pattern of…

Activities to help children develop the concept of right-left awareness are presented. Activities touch on lateral awareness (distinguishing between their right and left sides and labeling them) and directionality (using the language of left and right according to someone else's orientation). (CL)

The article provides a chart which summarizes conclusions drawn by researchers concerning the performance each hemisphere plays in human information processing, and gives suggestions on programs or activities which will enhance skills and significantly expand learning potential of gifted children.

The present investigation focussed on the neural substrates underlying linguistic distinctions that are signalled by prosodic cues. A production experiment was conducted to examine the ability of left- (LHD) and right- (RHD) hemisphere-damaged patients and normal controls to use temporal and fundamental frequency cues to disambiguate sentences…

We assessed 110 left-handed and 322 right-handed children aged from 3 to 10 years, using Bishop's card-reaching task. Manual body midline crossings were observed. A regular developmental trend was observed from 3 to 10 years: older children crossed the body midline more frequently when reaching for cards than did younger children. The factor age…
