[citation needed] The auditory cortex forms groupings based on fundamentals; in music, for example, this would include harmony, timing, and pitch. [18] The primary auditory cortex lies in the superior temporal gyrus of the temporal lobe and extends into the lateral sulcus and the transverse temporal gyri (also called Heschl's gyri).
The primary auditory cortex is surrounded by secondary auditory cortex, and interconnects with it. These secondary areas interconnect with further processing areas in the superior temporal gyrus , in the dorsal bank of the superior temporal sulcus , and in the frontal lobe .
The lemniscal classical auditory pathway is tonotopically organized and consists of the central nucleus of the inferior colliculus and the ventral medial geniculate body projecting to primary areas in the auditory cortex. The non-primary auditory cortex receives inputs from the extralemniscal non-classical auditory pathway, which shows a ...
Vision: The visual area known as V1, striate cortex, or (primary visual cortex, Brodmann area 17) is located on the calcarine sulcus deep within the inside folds of the occipital lobe. Hearing: The primary auditory cortex is located on the transverse gyri that lie on the back of the superior temporal convolution of the temporal lobes.
Located in the temporal lobe, the auditory cortex is the primary receptive area for sound information. The auditory cortex is composed of Brodmann areas 41 and 42, also known as the anterior transverse temporal area 41 and the posterior transverse temporal area 42, respectively.
Around the primary auditory cortex lies Wernickes area, a cortical area involved in interpreting sounds that is necessary to understand spoken words. Disturbances (such as stroke or trauma) at any of these levels can cause hearing problems, especially if the disturbance is bilateral. In some instances it can also lead to auditory hallucinations ...
This condition also affects the development of the auditory cortex, which gives rise to auditory functional deficits. There are fewer nerve fibres and less myelination in patients' primary auditory cortex, illustrated by the higher grey matter-to-white matter ratios in the Heschl gyrus. The cells and synapses undergo dystrophy in a deafness ...
The sensory cortex can refer sometimes to the primary somatosensory cortex, or it can be used as a term for the primary and secondary cortices of the different senses (two cortices each, on left and right hemisphere): the visual cortex on the occipital lobes, the auditory cortex on the temporal lobes, the primary olfactory cortex on the uncus of the piriform region of the temporal lobes, the ...
