The auditosensory cortex is the part of the auditory system that is associated with the sense of hearing in humans. It occupies the bilateral primary auditory cortex in the temporal lobe of the mammalian brain. [1] The term is used to describe Brodmann areas 41 and 42 together with the transverse temporal gyrus. [2]
Coronal section of a human brain. BA41(red) and BA42(green) are auditory cortex. BA22(yellow) is Brodmann area 22, HF(blue) is hippocampal formation and pSTG is posterior part of superior temporal gyrus. The auditory cortex is the part of the temporal lobe that processes auditory information in humans and many other vertebrates.
The auditory dorsal stream includes the posterior superior temporal gyrus and sulcus, inferior parietal lobule and intra-parietal sulcus. Both pathways project in humans to the inferior frontal gyrus. The most established role of the auditory dorsal stream in primates is sound localization.
The human auditory system is truly a remarkable and complex sense that is still being studied and understood. Conclusion. In conclusion, the human auditory system is a marvel of biological ...
[20] [24] [25] [26] Recently, evidence accumulated that indicates homology between the human and monkey auditory fields. In humans, histological staining studies revealed two separate auditory fields in the primary auditory region of Heschl's gyrus, [27] [28] and by mapping the tonotopic organization of the human primary auditory fields with ...
The angular gyrus is represented in orange, the supramarginal gyrus is represented in yellow, Broca's area in blue, Wernicke's area in green, and the primary auditory cortex in pink. In neuroscience and psychology , the term language center refers collectively to the areas of the brain which serve a particular function for speech processing and ...
The superior temporal gyrus also includes Wernicke's area, which (in most people) is located in the left hemisphere. It is the major area involved in the comprehension of language. The superior temporal gyrus is involved in auditory processing, including language, but also has been implicated as a critical structure in social cognition. [2] [3]
Tonotopic organization in the human auditory cortex has been studied using a variety of non-invasive imaging techniques including magneto- and electroencephalography (MEG/EEG), positron emission tomography , and functional magnetic resonance imaging . [29] The primary tonotopic map in the human auditory cortex is along Heschl's gyrus(HG ...
