Wikipedia
The cerebrum is a large part of the brain containing the cerebral cortex (of the two cerebral hemispheres), as well as several subcortical structures, including the hippocampus, basal ganglia, and olfactory bulb. In humans, the cerebrum is the uppermost region of the central nervous system. The telencephalon is the embryonic structure from which the cerebrum develops prenatally. In mammals, the dorsal telencephalon, or pallium, develops into the cerebral cortex, and the ventral telencephalon, or subpallium, becomes the basal ganglia. The cerebrum is also divided into approximately symmetric left and right cerebral hemispheres.
With the assistance of the cerebellum, the cerebrum controls all voluntary actions in the body.

She breathed through the top of her head and felt the cool relaxation come up from the smooth functionings of the diencephalon, the oldest part of the brain, which sat on the end of the spinal cord like a ball joint and let the hemispheres of the cerebrum tilt crazily about it while itself remaining still.
Physiologists assign to the cerebrum its functions, and neurological, as well as phrenological writers, have located them as represented in Fig.
