Chapter 34 deals with functional aspects of the cortical association areas. Some areas are specialized for integration of two or more sensory modalities; others integrate highly processed sensory information with information about intentions and goals. The posterior parietal cortex integrates visual and somatosensory information and is important for control of visually guided behavior and spatial orientation. The prefrontal cortex is of special importance for goal-directed and social behavior. The temporal association areas are concerned with high-level processing of auditory and visual information. The inferotemporal cortex is crucial for object recognition. The medial parts of the temporal lobe are of special importance for learning and memory. The insula is involved in pain perception, homeostasis, and bodily awareness. Language and speech depends on a network with two special hubs, Broca’s area and Wernicke’s area. Hemispheric specializations (lateralization) and the biologic bases of cognitive gender differences are also discussed.
