Final answer:
Yes, higher-order functions involve complex interactions among areas of the cortex, particularly within integrative areas that process multisensory information and coordinate sensory and motor functions.
Step-by-step explanation:
The interactions among different areas of the cerebral cortex that involve complex interactions for processing sensory, motor, and integrative information are indeed true. When considering higher-order functions such as coordination of visual and motor functions, the cortex engages in complex processing. These functions are observed in integrative areas of the cortex which lie between the primary sensory and motor regions and are responsible for combining and processing multiple types of sensory information and coordinating this with motor actions. Therefore, the statement that higher-order functions involve complex interactions among areas of the cortex is True.
