CEREBRAL CORTEX: LOCALIZATION OF FUNCTION AND ASSOCIATION PATHWAYS •<br />

The cerebral cortex is organized into functional regions. In addition<br />

to specific areas devoted to sensory and motor functions, there<br />

are areas that integrate information from multiple sources. The<br />

cerebral cortex participates in advanced intellectual functions,<br />

including aspects of memory storage and recall, language, higher<br />

cognitive functions, conscious perception, sensory integration, and<br />

planning/execution of complex motor activity. General cortical<br />

areas associated with these functions are illustrated.<br />
