Sitting between the cerebral cortex and the brain stem is another segment of the brain, called the diencephalons, which combines the functions of the brain stem with the cerebral cortex.
Areas covered by the diencephalon are the hypothalamus and the thalamus which process our sensory information such as hunger and thirst, including our sexual and emotional responses.
