Final answer:
The portion of the cerebral cortex responsible for processing auditory input, speech, memory, and emotion, located above the ears, is the temporal lobe.
Step-by-step explanation:
The portion of the cerebral cortex lying roughly above the ears that includes the auditory areas, each receiving information primarily from the opposite ear, is known as the temporal lobe. The temporal lobe is an integral part of the cerebral cortex that processes auditory input. It also plays key roles in speech, memory, and emotion processing. This lobe houses the auditory cortex, the main area responsible for processing auditory information, and also includes important language comprehension areas such as Wernicke's area.
