cerebrum


human brain, cross-section
The largest portion of the human and vertebrate brain. It consists of two cerebral hemispheres, which develop from the embryonic forebrain. These hemispheres have an outer convoluted layer of gray matter – the cerebral cortex – and an inner layer of white matter. The two halves are linked by the corpus callosum. Each hemisphere of the cerebrum is subdivided into four lobes visible from the outside. They are the frontal, parietal, occipital, and temporal lobes.

The cerebrum is the integrating center for memory, learning, emotions, and other highly complex functions of the central nervous system.
