Final answer:
The outer layer of the brain is the cerebral cortex, involved in higher-level brain functions and divided into two hemispheres connected by the corpus callosum.
Step-by-step explanation:
The outer layer of the brain is known as the cerebral cortex, which is associated with higher level processes such as consciousness, thought, emotion, reasoning, language, and memory. The cerebral cortex is a thick piece of nervous system tissue that is highly folded, with hills called gyri and valleys called sulci. It is made up of two hemispheres, right and left, which are separated by a large sulcus known as the longitudinal fissure, and connected by a thick fiber bundle known as the corpus callosum.
The outer layer of the brain is called the cerebral cortex. It is a highly folded, thin outer layer of the cerebrum where most information processing in the brain takes place. The cerebral cortex is made up of two hemispheres, right and left, which are separated by a large sulcus and connected by a fiber bundle called the corpus callosum.
