ResumoAs a typical feature of primate evolution, the integration cortex, the most generalized neocortical structure has become the most predominant cortex with the greatest possibility for further differentiation. The thrust of the expanding posterior parieto-occipitotemporal integration cortex in primates produces a temporal lobe from the temporal cortex. This lobe formation is absent in other mammals such as carnivores and ungulates. The increasing size of the temporal lobe within primate evolution from prosimian to man is determined by an enormous expansion of the temporal integration cortex between the auditory and entorhinal regions (Fig. 3). The evidence for polysensory input of the posterior part of the temporal integration cortex, which is involved in the elaboration of memory mechanisms of language, is discussed. In addition, the question of a visual association area in the posterior part of the superior temporal sulcus opposite to the auditory region is examined. The development of language in human evolution is correlated with a significant spread of the auditory parakoniocortex in the dominant hemisphere. This spread is reflected in the caudal shifting of the posterior margin of the supratemporal plane (Fig. 6) and follows the rule that, in evolution, fast growing areas exert growth pressure at their borderlines.
