• Results of this work show, in the inferior frontal gyrus and in the different portions into which it was divided, asymmetry of weight and cortical surface and left predominance in the posterior portion, which is concerned with language. In spite of the difference among the absolute individual values, the correlation between weight and surface values is excellent in all cases, and the weight and surface ratio is the same for the portions related to language and different for the remainder of the inferior frontal gyrus.
