The association cortex is a part of the cerebral cortex that performs complex cognitive functions. [ 1 ] [ 2 ] Unlike primary sensory or motor areas , which process specific sensory inputs or motor outputs, the association cortex integrates information from various sources to support higher-order cognitive processes.
In mammalian brain anatomy, the prefrontal cortex (PFC) covers the front part of the frontal lobe of the cerebral cortex. It is the association cortex in the frontal lobe. [2] The PFC contains the Brodmann areas BA8, BA9, BA10, BA11, BA12, BA13, BA14, BA24, BA25, BA32, BA44, BA45, BA46, and BA47. [1]
Patients otherwise exhibit a relatively normal control of language. The symptoms of conduction aphasia suggest that the connection between the posterior temporal cortex and frontal cortex plays a vital role in short-term memory of words and speech sounds that are new or have just been heard. The arcuate fasciculus is the main connection between ...
Area 12 – Orbitofrontal area (used to be part of BA11, refers to the area between the superior frontal gyrus and the inferior rostral sulcus) Area 13 and Area 14 * – Insular cortex; Area 15 * – Anterior temporal lobe; Area 16 – Insular cortex; Area 17 – Primary visual cortex (V1) Area 18 – Secondary visual cortex (V2)
Brodmann area 6 (BA6) is part of the frontal cortex in the human brain. Situated just anterior to the primary motor cortex , it is composed of the premotor cortex and, medially, the supplementary motor area (SMA). This large area of the frontal cortex is believed to play a role in planning complex, coordinated movements.
The uncinate fasciculus is a white matter association tract in the human brain that connects parts of the limbic system such as the temporal pole, anterior parahippocampus, and amygdala in the temporal lobe with inferior portions of the frontal lobe such as the orbitofrontal cortex.
Association fibers are axons (nerve fibers) that connect cortical areas within the same cerebral hemisphere. [ 1 ] In human neuroanatomy, axons within the brain, can be categorized on the basis of their course and connections as association fibers, projection fibers , and commissural fibers . [ 1 ]
The superior longitudinal fasciculus (SLF) is an association tract in the brain that is composed of three separate components. [1] [2] It is present in both hemispheres and can be found lateral to the centrum semiovale and connects the frontal, occipital, parietal, and temporal lobes. [2]
