The auditory cortex plays a crucial role in processing and interpreting auditory information, making it essential for understanding sounds, such as speech, music, and environmental noises. This region of the brain is located in the temporal lobe and receives auditory input from the ears, allowing it to analyze various aspects of sound, including pitch, volume, and rhythm.

Through its complex neural connections, the auditory cortex enables individuals to recognize patterns in sound, localize sound sources, and derive meaning from auditory stimuli. This processing is vital for communication and interaction with the environment, as it allows for discerning important sounds from background noise and responding appropriately.

The other choices, while related to the auditory system or sensory functions, do not accurately describe the primary function of the auditory cortex. Amplifying sound waves pertains more to the mechanical aspects of hearing rather than the neural processing that occurs in the auditory cortex. Detecting head movements is primarily the role of the vestibular system, which is involved in balance and spatial orientation, not directly related to processing sound. Additionally, assisting in balance is also linked to the vestibular system and not to the auditory cortex's core functions. Thus, the primary role of the auditory cortex is indeed the processing and interpretation of auditory information.
