The auditory cortex is involved in tasks such as identifying and segregating "auditory objects" and identifying the location of a sound in space. For example, it has been shown that A1 encodes complex and abstract aspects of auditory stimuli without encoding their "raw" aspects like frequency content, presence of a distinct sound or its echoes.
The auditosensory cortex defines Brodmann area 42, which is part of the primary auditory cortex.It is also known as the posterior transverse temporal area, [2] located superiorly within the temporal lobe of the cerebral cortex.
The superior temporal gyrus contains several important structures of the brain, including Brodmann areas 41 and 42, marking the location of the primary auditory cortex, the cortical region responsible for the sensation of basic characteristics of sound such as pitch and rhythm. We know from research in nonhuman primates that the primary ...
Brodmann areas 41 and 42 are parts of the primary auditory cortex.. Brodmann area 41 is also known as the anterior transverse temporal area 41 (H). It is a cytoarchitectonic division of the cerebral cortex occupying the anterior transverse temporal gyrus (H) in the bank of the lateral sulcus on the dorsal surface of the temporal lobe.
This auditory (or tonotopic) map is similar to the homunculus map of the primary motor cortex. Some areas of the superior temporal gyrus are specialized for processing combinations of frequencies, and other areas are specialized for processing changes in amplitude or frequency. The superior temporal gyrus also includes Wernicke's area, which ...
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.
The inferior colliculus has three subdivisions: the central nucleus, a dorsal cortex by which it is surrounded, and an external cortex which is located laterally. [1] Its bimodal neurons are implicated in auditory-somatosensory interaction, receiving projections from somatosensory nuclei.
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.
