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.

Asymmetries of the Left and Right Temporal Lobes. This study concludes, on the basis of the measurements made, that there are differences between the right and left temporal lobes. Three different measurements were taken using a pachimeter Mitutoyo and a goniometer Card on both hemispheres: July 11 Medisur, Vol 16, Iss 4, Pp Our sample was composed of 40 post mortem adult brains of both sexes, which crebral investigated at the Human Anatomy Laboratory of the Nove de Julho University Center in Sao Paulo, Brazil.

FMRI study using visual verb generation and word pair paradigms. The author realized a lxteralidad in which he studied the anatomical asymmetries between the cerebral hemispheres, drawing attention to the asymmetry observed in the temporal plane, and also highlighting that the same is difficult to study in recently autopsied cadavers due to low density, thus suggesting that the same can only be analyzed with greater rigor after fixation in formol or in another way.

RESULTS 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: It is likely that the most conspicuous asymmetry is that of the temporal lobe, and although researchers have measured it in various lateralidd ways, it is still little understood Crow.

Distance from the lateral sulcus to the inferior margin of the temporal lobe. 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.

It is important to highlight here that the hemispheres of the brain are not identical organs, either from an anatomical or from a functional view point, and we suggest that new studies are undertaken so that we can become familiar with and understand asymmetry in its essence.

The aim of this work was study different measures between right and left brain hemispheres, related in previous studies, comparing 40 cadaveric cerehral, with follow results: For Caldas, cerebral dominance is a fundamental characteristic of the process of species evolution, with the left hemisphere and its functions representing the new acquisition of the human species that distinguished it from other species, as proposed in the concept of dominance.

The authors of the time nevertheless considered that the two sides of the brain were symmetric laterallidad that each organ had its homolog on the other side, which lacked a functional equilibrium Caldas, 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.

Search Results Display Settings Results per page: Participants with bilateral activation in left and right superior temporal-inferior parietal regions had better language function than those with either predominantly left- or right-sided unilateral activation. 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.

This time, they observed a lqteralidad of 7cm in the left lateral sulcus compared to the right in an extensive sample.

The relation between cerebral dominance and visual analytic skills in Iraqi medical students, a cross sectional analysis. Angle formed between the lines of the collateral sulcus and the inferior margin of the temporal lobe.

Left hemisphere regions doninancia critical for language in the face of early left focal brain injury.

Medisur, Vol cerebra, Iss 4, Pp Record details. 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.

Cerebral asymmetries are similar both in modern and in fossil humans. 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.

Considering these factors, the aim of this study is to verify whether the temporal lobes are anatomically different. 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 lateraldad language function following early injury.
