Unimodal (modality specific) association cortex (yellow)
Includes somatosensory association cortex, auditory association cortex, visual association, and motor association cortex (premotor cortex and supplementary motor cortex)
Unimodal (modality specific) association cortex refers to a type of association cortex that is specialized for processing information from a specific sensory modality, such as vision, audition, or touch. It is located in the yellow region of the cerebral cortex.
This area receives input from the primary sensory cortex, which is responsible for processing sensory information from the thalamus. The unimodal association cortex helps to further process this information by integrating it with other sensory information and with past experiences.
For example, the visual association cortex receives input from the primary visual cortex and is responsible for recognizing and identifying visual stimuli that are present in the environment. It helps us to identify objects, faces, and colors. The auditory association cortex receives input from the primary auditory cortex and is responsible for processing sounds such as speech, music, and environmental noises. The somatosensory association cortex receives input from the primary somatosensory cortex and is responsible for processing tactile information such as pressure, texture, and temperature.
These areas are also connected with other areas of the brain, such as the prefrontal cortex, which is important for decision-making and planning; the limbic system, which is involved in emotions and motivation; and the basal ganglia, which are involved in motor control. Together, these areas help to integrate sensory information with other cognitive functions such as memory, attention, and perception, allowing us to make sense of the world around us in a meaningful way.
