Cerebral Hemispheres

The cerebral hemispheres are a pair of parts of the brain that control distinct physiologic and cognitive functions. Each hemisphere is divided into four lobes: the frontal, parietal, temporal, and occipital. The hemispheres are important for a variety of functions, including sensory perception and the regulation of language, emotions, and behaviors. They are also key for higher cognitive functions, such as memory, learning, and reasoning. The hemispheres can also be separated into left- and right-sided functions. The left hemisphere is responsible for controlling more logical and analytical processes, and the right hemisphere is responsible for controlling more creative and intuitive functions. The interactions between the two hemispheres also contribute to a person's overall cognitive functioning.
