• The Forebrain is the largest part of the brain and comprises two hemispheres: the left hemisphere and the right hemisphere. 
• The forebrain includes the cerebrum, which is responsible for processing sensory information, controlling movement, and managing higher-level cognitive functions such as thought, emotion, and memory.

• Forebrain (includes the cerebrum, thalamus, and hypothalamus)
• Midbrain (connects the forebrain to the hindbrain, and regulates auditory and visual processing)
• Hindbrain (includes the cerebellum, pons, and medulla oblongata, and regulates movement, balance, and basic bodily functions)
