Se encuentra separada de los lobulos frontal, central, parietal y temporal por el surco limitante (Figura 13, 2, 3, 4) o tambien llamado surco circular por encerrar al lobulo de la insula ,este surco presenta tres bordes; anterior, superior e inferior, tres angulos; anterosuperior, anteroinferior y posterior.
The following measurements were taken: (1) the temporal depth was measured as the distance from the temporal end point of the common boundary between the temporal and insular lobes to the outermost border of the temporal lobe cortex; (2) the SF depth was measured as the distance from the same point to the inner cortical table of the parietal bone; (3) the SF width was measured as the distance from the same point to the frontal end point of the common boundary between the frontal and insular lobes; (4) the uncovered insula width was measured as the minimum distance between the temporal lobe prominence and the frontal lobe prominence.
