Meaning Apprehension in the Cerebral Hemispheres
… the results strongly suggest that both hemispheres were equally capable of accessing associative information and similarly sensitive to associative strength. Contrary to prominent cognitive neuroscience theories of meaning apprehension, this work shows that the hemispheres exhibit broad …

Verbal Creativity and Ambiguity Resolution in the Cerebral Hemispheres
This study examined hemispheric differences in ambiguity resolution in subjects who vary on measures of creativity. Subjects were classified as either low, moderate, or high creative based on the results of convergent and divergent thinking tests as well as a personality inventory. Two experiments …

Individual and Joint Contributions of the Cerebral Hemispheres to Language Comprehension
… thus a network of brain areas, in both cerebral hemispheres, is recruited during everyday language and discourse processes. The three experiments presented here examine the idea that some typically-studied language processes are composed of distinct contributions from each hemisphere, …

The Cerebral Hemispheres Cooperate to Perform Complex but Not Simple Tasks
… to which a division of processing across the hemispheres (i.e., across-hemisphere processing) underlies performance when within- and across-hemisphere processing are equally possible. When task complexity was relatively low, performance in a midline condition (which allowed for either within- …

Predictive inference generation in the cerebral hemispheres: An investigation of time course and reader goals
… of how predictive inferences are process in the cerebral hemispheres. Thus, the current study used a divided visual field paradigm to investigate how reading goals, textual constraint, and SOA influence predictive inference generation in the right and left hemisphere. Four experimental studies …

An analysis of word generation by the left and right cerebral hemispheres : the effects of imposed speed-stress instructions
A left hemisphere advantage in response accuracy was obtained for an adjective gener a tion task independent of fluctuations in subjects' speed-accuracy criteria. This effect resulted despite the fact that stimuli were not repeated over trials and despite the controls taken to minimize eye movement …

Influences of Hemispheric Specialization and Interaction on Task Performance
… dividing information processing between the cerebral hemispheres improves performance. The research in this dissertation provides evidence that dividing processing between the cerebral hemispheres improves performance when a task is computationally complex, but only to the extent that the …

Preliminary Investigations Into the Etiology and Pathogenesis of Equine Leucoencephalomalacia
… death, and leucomalacia in one or both of the cerebral hemispheres.

The effect of television viewing on college students : an EEG analysis of cerebral asymmetry
… that while there were no differences between cerebral hemispheres, there were significant increases in the amount of alpha brain .wave production (p <. 01) during the trials.</p> <p>The results of this study support the first hypothesis that "EEG alpha levels will increase with repeated …

Cerebral asymmetry in facial affect perception of women: neuropsychological effects of depression
… study of the influence of depression on the cerebral hemispheric processing of Ekman and Friesen’s (1976) happy, sad, and neutral emotional faces. A dynamometer was also used as a standardized measure of hemispheric motor functioning such as hand grip strength, perseveration, and fatigue. …

The Role of Sonic Hedgehog in the Hypothalamus
… the forebrain is required early to bifurcate the cerebral hemispheres and eye vesicles as well as to specify a rostroventral forebrain region, the hypothalamus. We hypothesized that Shh expressed later in the hypothalamus may be required for other known functions of Shh, such as patterning within …

Interhemispheric transfer in a marsupial : a behavioural investigation of interhemispheric transfer of visual information in Trichosurus vulpecula
… that transfer of visual information between cerebral hemispheres can take place in an animal which lacks a corpus callosum, and that the forebrain commissures may be the functional equivalent, in this marsupial, of the corpus callosum in eutherians. A further eight animals received …

Interhemispheric communication during face processing
It is widely acknowledged that the cerebral hemispheres do not operate in isolation during the processing of complex visual stimuli. Patterns of interhemispheric communication are believed to be integral to cognitive abilities yet despite this, both the circumstances under which communication takes …

Hemisphere differences in idiom comprehension: The influence of ambiguity, transparancy, and familiarity
… how idioms are processed in the right and left hemispheres. It is possible that not all idioms are processed similarly in the hemispheres, and that several factors between idioms may affect hemispheriC processing. First, the plausibility of an idiom's literal interpretation (i.e., ambiguity) may …

Hemispheric reactivity to bright light exposure: a test of the relationship between age, hemi-activation and depression
… to be representative of the left and the right cerebral hemispheres. The left hemisphere appears to be more responsive to ambient light level, with the right hemisphere being more responsive to ambient noise level. The present study sought to provide further support of selective hemispheric …

The Construct of Personality and Hemispheric Usage
… on the differential contributions of the cerebral hemispheres to human experience and behavior have demonstrated that the hemispheres are lateralized for cognitive strategies and, possibly, for emotional valance. Recently researchers have demonstrated that the hemispheres may also be …

An fMRI study of object recognition and cerebral laterality
… visual cortex, within and between the two cerebral hemispheres, are involved in visual processing of different kind of visual objects is not known. In two fMRI studies of words and faces, we compare univariate and multivariate analysis results for neural differences between and within …

On the meaning of numbers: flexibility in the structure and retrieval of memories for Arabic numerals
… in arithmetic contexts, and examined how the two cerebral hemispheres approach reading equations and evaluating potential answers. These experiments revealed similarities in how the hemispheres respond to contextually congruous and incongruous answers but differences in how they evaluate other …

Potential for change: Characterizing synaptic plasticity following visual discrimination learning in adult rats.
… (changes in short-term plasticity in both cerebral hemispheres) and localized changes (greater LTP levels in the hemisphere contralateral to the open eye). The enhanced LTP in the primary visual cortex (V1) was blocked by an NR2B antagonist, suggesting that training resulted in changes in …

Atypical Lateralization of Language and Face Processing in Autism Spectrum Disorder
… domains is typically lateralized across the cerebral hemispheres, such that language and face processing are dominant within the left and right hemispheres, respectively. Furthermore, the degree of lateralization is related to behavioural proficiency in both domains. Converging evidence …
