In the mid-19th century scientists first began to make discoveries regarding lateralization of the brain, or differences in anatomy and corresponding function between the brain's two hemispheres. Franz Gall, a German anatomist, was the first to describe what is now known as the Doctrine of Cerebral Localization. Gall believed that, rather than ...
The Halstead–Reitan Neuropsychological Test Battery (HRNB) and allied procedures is a comprehensive suite of neuropsychological tests used to assess the condition and functioning of the brain, including etiology, type (diffuse vs. specific), localization and lateralization of brain injury.
The best example of an established lateralization is that of Broca's and Wernicke's areas, where both are often found exclusively on the left hemisphere. Function lateralization, such as semantics, intonation, accentuation, and prosody, has since been called into question and largely been found to have a neuronal basis in both hemispheres. [6]
1848 edition of American Phrenological Journal published by Fowlers & Wells, New York City. Phrenology, created by Franz Joseph Gall (1758–1828) and Johann Gaspar Spurzheim (1776–1832) and best known for the idea that one's personality could be determined by the variation of bumps on their skull, proposed that different regions in one's brain have different functions and may very well be ...
Emotional lateralization is the asymmetrical representation of emotional control and processing in the brain. There is evidence for the lateralization of other brain functions as well. Emotions are complex and involve a variety of physical and cognitive responses, many of which are not well understood. The general purpose of emotions is to ...
In ants, Temnothorax albipennis (rock ant) scouts show behavioural lateralization when exploring unknown nest sites, showing a population-level bias to prefer left turns. One possible reason for this is that its environment is partly maze-like and consistently turning in one direction is a good way to search and exit mazes without getting lost ...
For multiple bonds and lone pairs, different localization procedures give different orbitals. The Boys and Edmiston-Ruedenberg localization methods mix these orbitals to give equivalent bent bonds in ethylene and rabbit ear lone pairs in water, while the Pipek-Mezey method preserves their respective σ and π symmetry .
Also, when looking at localization of chronic hospitalized patients with injuries in the frontal, sensorimotor, temporal, and parietal-occipital areas, the test was 88% effective in localizing the brain damage, but the limit to this report was a small sample size of 60 patients.
