Asymmetries of the Left and Right Temporal Lobes. Anatomical brain asymmetries are subtle and still little studied in humans.

Among all the animals, humans have the most asymmetric brains Crow The language faculty and handedness are localized on the left side. The objective this paper is to verify whether the temporal lobes are anatomically different.

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. Three different measurements were taken using a pachimeter Mitutoyo and a goniometer Card on both hemispheres: 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.

Results were submitted to 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.

The measurements taken showed differences between the right and left temporal lobes. Brain; Asymmetry; Temporal Lobe.

At the end cerebrrales 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 cerebralees 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, 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.

In this way, the concept was established that asymmetry is the defining characteristic of the human brain Crow, lpbulos From an anatomical point of view, it has been known since the time of Broca that human ceerbrales asymmetries are subtle. 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.

Considering these factors, the aim of this study is to verify whether the temporal lobes are anatomically different.

Length of the lateral sulcus. Distance from the lateral sulcus to the inferior margin of the temporal lobe. Angle formed between the lines of the collateral sulcus and the inferior margin of the temporal lobe. 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 of this lbulos in anatomic studies were analysed with foloowing values: 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.

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.

This time, they observed a difference of 7cm in the left lateral sulcus compared to the right in an extensive sample. 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 author realized a cerebrxles 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 oobulos that the same can only be analyzed with greater rigor after fixation in formol or in another way.

Cerebral asymmetries are similar both in modern and in fossil humans. Considered by Rubens et cerevrales.

This study concludes, on the olbulos of the measurements made, that there are differences between the right and left temporal lobes. 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.
