Skosmos: UNESCO: Lateral dominance

From an anatomical point of view, it has been known since the time of Broca that human cerwbral asymmetries are subtle. Item request has been placed!

Brain; Asymmetry; Temporal Lobe. At the same time, on reinvestigating this problem with a sample consisting of adult human brains, significant asymmetries were found between the right and left hemispheres, with results demonstrating that the temporal plane was 0.

Ml – the length of the lateral sulcus; M2 – the distance from the lateral sulcus to the inferior margin of the inferior temporal gyrus, and M3 – the angle formed between the lines of the collateral sulcus and the inferior margin of the inferior temporal gyrus. The advantage conferred by left inferior frontal and bilateral temporal involvement demonstrated in our study supports a strong predisposition for typical neural language organization, despite an intervening injury, and argues against models suggesting that the right hemisphere fully accommodates language function following early injury.

Three different measurements were taken using a pachimeter Mitutoyo and a goniometer Card on both hemispheres: Length of the lateral sulcus. Sylvian fissure morphology and asymmetry in men and women: FMRI study using visual verb generation and word pair paradigms.

Dominancia cerebral ; habilidad ; lateralidad funcional Source: The objective this paper is to verify whether the temporal lobes are anatomically different. Distance from the lateral sulcus to the inferior margin of the temporal lobe. Considering these factors, the aim of this study is to verify whether the temporal lobes are anatomically different.

Cerebral Dominance and associated factors in fourth year dentistry students Authors: Cerebral dominance ; Experimental design ; Data analysis. It is likely that the most conspicuous asymmetry is that of the temporal lobe, and although researchers have measured it in various different ways, it is still little understood Crow.

Aroundafter studying various cases of left hemisphere lesions and alterations in language, Paul Broca became convinced of the correctness of the studies of Mark Dax, which stated that language ability was localized on the left side of the brain, given that sinceit had already been considered that man, among all the other animals, had the most asymmetric brain with the largest quantity of acquired abilities, of which language was the highest, since it distinguished humans from animals.

Cerebral dominance ; Speech perception ; Cerebral hemispheres — Physiology Source: Brain ; Pt 6: Our sample was composed of 40 post mortem adult brains of both sexes, which were investigated at the Human Anatomy Laboratory of the Nove de Julho University Center in Sao Paulo, Brazil.

This was true independent of either the amount of brain injury or the extent that the injury was located in classical cortical language processing areas.


The measurements taken showed differences between the right and left temporal lobes. The authors of the time nevertheless considered that the two sides of the brain were symmetric and that each organ had its homolog on the other side, which lacked a functional equilibrium Caldas, Speech cerebrql ; Stuttering ; Brain physiology Source: The aim of this work was study different measures between right and left brain hemispheres, related in previous studies, comparing 40 cadaveric brains, with follow results: Results were submitted laterapidad a statistical analysis ANOVA and demonstrated that Ml was larger in the left hemisphere, by contrast with the data obtained for M2 and M3, which were larger in the right hemisphere.

Anatomical study of cerebral asymmetry in the temporal lobe of humans, chimpanzees, and rhesus monkeys. Asymmetry of the lateral Sylvian fissures in man.

Resumen A predominant theory regarding early stroke and its effect on language development, is that early left hemisphere lesions trigger compensatory processes that allow the right hemisphere to assume ceerebral language functions, and this is thought to underlie the near normal language development observed after early stroke.

Otto, Tobias 1 ; Zijlstra, Fred R. The results cited above corroborate the subsequent work by the same authors, based on lateralization for language in the cerebral hemispheres, for which there is a consensus creebral the literature, on the basis of the structural asymmetries found.
