As an expert in the field of neuroscience, I can tell you that the process of hearing is a complex one that involves several parts of the brain, but the primary area responsible for processing auditory information is the auditory cortex. The auditory cortex is located within the temporal lobe of the cerebrum, which is the largest part of the human brain.
The journey of sound begins when sound waves enter the ear and are transformed into electrical signals by the cochlea in the inner ear. These signals are then transmitted via the auditory nerve to the brainstem. From there, the signals travel to the medulla oblongata and then to the pons, which are parts of the brainstem involved in relaying auditory information.
After the brainstem, the auditory signals move up to the inferior colliculus and superior colliculus in the midbrain, which are part of the tectum. These areas are involved in reflexive responses to sound, such as turning your head towards a sudden noise.
The auditory pathway then continues to the thalamus, a crucial relay station for sensory and motor signals. Within the thalamus, the medial geniculate body (MGB) is particularly important for auditory processing.
Finally, the auditory signals reach their destination in the auditory cortex. The primary auditory cortex, also known as the core region, is where initial processing of sound occurs. It is responsible for basic sound localization and the perception of simple sounds. Surrounding the core region is the belt area, which processes more complex sounds, and further out is the parasylvian area or parabelt, which is involved in the processing of even more complex auditory information.
It's important to note that while the auditory cortex is the primary area for hearing, the process is not isolated. The brain integrates auditory information with other sensory inputs and cognitive functions. For example, the cerebellum, which is located under the cerebrum, plays a role in coordinating the timing of muscle movements, which can be relevant for the fine control of head and ear movements in response to auditory stimuli.
The cerebrum itself is composed of two hemispheres, the right and the left, each with specialized functions. While the auditory cortex is predominantly involved in hearing, other areas of the cerebrum contribute to higher-level auditory processing, such as understanding speech, memory, and emotional responses to sounds.
In summary, the auditory cortex in the temporal lobe is the primary region responsible for hearing, but it works in concert with other parts of the brain to create our full experience of sound. The process of hearing is a testament to the intricate and interconnected nature of the human brain.

The Occipital Lobe is located at the back of the skull and controls vision. The Temporal Lobes are located on each side of the head above the ears. They control hearing and are related to smell, taste and short-term memory (especially visual and verbal).
