The cerebral cortex is the largest region of the mammalian brain and plays a key role in memory, attention, perception, cognition, awareness, thought, language, and consciousness. The cerebral cortex is the most anterior (rostral) brain region and consists of an outer zone of neural tissue called gray matter, which contains neuronal cell bodies. It is also divided into left and right cerebral hemispheres by the longitudinal fissure, but the two hemispheres are joined at the midline by the corpus callosum.

Based on this passage, where is the cerebral cortex located in the brain? Let's give stream of consciousness first:
To answer the question, consider the following: The cerebral cortex is the most anterior (rostral) brain region and consists of an outer zone of neural tissue called gray matter, which contains neuronal cell bodies.
So, the final answer is the most anterior ( rostral ) brain region.
