What is central nervous system that commonly associated with intelligence?

The prefrontal cortex (PFC)

The prefrontal cortex (PFC) is a region of the cerebral cortex located at the front of the brain. It is associated with higher-order cognitive functions such as intelligence, planning, decision-making, and social behavior. The PFC is involved in a variety of cognitive processes, including:

* Attention: The PFC helps to regulate attention and to focus on relevant information.

* Memory: The PFC is involved in the formation and retrieval of memories.

* Language: The PFC is involved in language processing, including speaking, understanding, and reading.

* Problem-solving: The PFC is involved in solving problems and making decisions.

* Social behavior: The PFC is involved in social behavior, including understanding the intentions of others and acting in accordance with social norms.

The PFC is a complex and highly interconnected region of the brain. It is still not fully understood how the PFC contributes to intelligence, but it is clear that it plays a vital role in this cognitive ability.
