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.
The auditory cortex takes part in the spectrotemporal, meaning involving time and frequency, analysis of the inputs passed on from the ear. The cortex then filters and passes on the information to the dual stream of speech processing. [5] The auditory cortex's function may help explain why particular brain damage leads to particular outcomes.
For example, Brodmann areas 1, 2 and 3 are the primary somatosensory cortex; area 4 is the primary motor cortex; area 17 is the primary visual cortex; and areas 41 and 42 correspond closely to primary auditory cortex. Higher order functions of the association cortical areas are also consistently localized to the same Brodmann areas by ...
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 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 ...
Primary auditory neurons carry action potentials from the cochlea into the transmission pathway shown in the adjacent image. Multiple relay stations act as integration and processing centers. The signals reach the first level of cortical processing at the primary auditory cortex (A1), in the superior temporal gyrus of the temporal lobe . [ 6 ]
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 ...
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 ...
