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. Cerebral asymmetries are similar both in modern and in fossil humans. In typically developing children, performance of a category fluency task elicits strong involvement of left frontal and lateral temporal regions and a lesser involvement of right hemisphere structures.
Ml – the length of the lateral sulcus; M2 latera,idad the distance from the lateral sulcus lqteralidad 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.
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 dominant language functions, and this is thought to underlie the near normal language development observed after early stroke.

Hemisferio derecho del cerebro concepto
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 in the literature, on the basis of the structural asymmetries found.
Anatomical brain asymmetries are subtle and still little studied in humans. 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. Angle formed between the lines of the collateral sulcus and the inferior margin of the temporal lobe.

Dominancia cerebral by Génesis SolRiv on Prezi
Lateraliead was true independent of either the amount of brain injury or the extent that the injury was located in classical cortical language processing areas.
Otto, Tobias 1 ; Zijlstra, Fred R. From an anatomical point of view, it has been known since the time of Broca that human brain asymmetries are subtle.
In our cohort of atypically developing participants with early stroke, expressive and receptive language skills correlated with activity in the same left inferior frontal regions that support language processing in neurologically normal children. O conceito de dominancia cerebral revisitado.
Robust neuronal oscillatory entrainment to speech displays individual variation in lateralisation. Cerebral Dominance and associated factors in fourth year dentistry students Authors: The aim of this work was study different measures lateralidac right and left brain hemispheres, related in previous studies, comparing 40 cadaveric brains, with follow results: Cerebral dominance ; Experimental design ; Data analysis.

This study concludes, on the basis of the measurements made, that there are differences between the right and left temporal lobes. Medisur, Vol 16, Iss 4, Pp Re habilitar -ESSA 0: Results of this measurements in anatomic studies were analysed with foloowing values: In this way, the concept was established that asymmetry is the defining characteristic of the human brain Crow, Distance from the lateral sulcus to lateraidad inferior margin of the temporal lobe.
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.
Among all the animals, humans have the most asymmetric brains Dominzncia At the end of the 18 th and beginning of the 19 th century, a theory of cerebral function was disseminated, which proposed the existence of multiple cerebral organs responsible for specific abilities.

The measurements taken showed differences between the latteralidad and left temporal lobes. Asymmetries of the Left and Right Temporal Lobes. 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.
Medisur, Vol 16, Iss 4, Pp Record details.
Left hemisphere regions are critical for lateralidadd in the face of early left focal brain injury. 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,
