What are the core belt and Parabelt areas?
The parabelt region is located on the surface of the superior temporal gyrus (STG). The core and belt regions lie on the superior temporal plane, visible after graphical removal of the overlying parietal and frontal opercula (cut). Area TPO lies on the upper bank of the superior temporal sulcus.
What does auditory cortex mean?
The auditory cortex is a network of areas in the part of the brain that receives inputs from the subcortical auditory pathways in the brainstem and thalamus.
What part of the brain is responsible for auditory processing?
The primary auditory cortex (A1) is located on the superior temporal gyrus in the temporal lobe and receives point-to-point input from the ventral division of the medial geniculate complex; thus, it contains a precise tonotopic map.
What is the function of the auditory association area?
The auditory association area is a part of the brain that is found in Wernicke’s area. It is responsible for processing acoustic (sound) signals that the brain interprets as sounds, speech or music.
What do the belt and Parabelt do?
The belt is the area immediately surrounding the core; the parabelt is adjacent to the lateral side of the belt. Besides receiving input from the ears via lower parts of the auditory system, it also transmits signals back to these areas and is interconnected with other parts of the cerebral cortex.

What happens if auditory cortex is damaged?
Humans with damage to the auditory cortex may also experience difficulty in perceiving the ordering of simple sounds, suggesting a fundamental disorder in processing sound across time, a temporal auditory disorder. The secondary auditory pathway is essential for sound detection and localization.
What neurological processes are taking place when a person is hearing music?
When we listen to music, sound vibrations in the ear are converted to neural messages and transmitted to the thalamus, the brain’s “sensory relay station.” After reaching the thalamus, sound information is passed to the auditory cortex and instantaneously broken down into many different elements including, but not …
What happens if the auditory association area is damaged?
Hence, damage to left auditory association cortex specifically impairs perceptual and conceptual processing of sounds from everyday objects. In support of modality-specific theories, these findings strongly evidence the necessity of auditory association cortex in coding sound-related conceptual information.
