Association cortex is divided into two parts
Unimodal and Heteromodal
The association cortex can be broadly divided into two parts – the prefrontal cortex and the posterior association cortex.
1. Prefrontal Cortex: This region is located at the front of the brain and is involved in higher cognitive functions such as decision-making, personality, social behavior, and other executive functions. It is involved in planning, organizing, and executing complex behaviors and is also responsible for working memory, attention, and problem-solving.
2. Posterior Association Cortex: This region is located at the back of the brain and is involved in processing and integrating information from different sensory modalities. It includes areas such as the parietal cortex, temporal cortex, and occipital cortex. The parietal cortex is involved in processing spatial information and attention, the temporal cortex is involved in processing auditory and language information, and the occipital cortex is involved in processing visual information.
The association cortex plays a crucial role in higher cognitive functions such as perception, interpretation, language, memory, and cognition. It connects various sensory and motor areas of the brain and integrates information to form a coherent perception of the world around us. Damage to the association cortex can result in various neurological disorders such as agnosia, apraxia, and aphasia, which can lead to problems in recognizing objects, performing skilled movements, and producing or understanding language.
