What is the main function of your brain?

Your brain controls Everything you do. It doesn't have a 'main' function apart from keeping you alive. There are A LOT of neurons in your brain and they pass along the information to your body to keep it functioning, conscious or unconscious. Take a psychology class, it will explain a whole lot more. There are 4 parts of the brain:

• Frontal Lobe- associated with reasoning, planning, parts of speech, movement, emotions, and problem solving
• Parietal Lobe- associated with movement, orientation, recognition, perception of stimuli
• Occipital Lobe- associated with visual processing
• Temporal Lobe- associated with perception and recognition of auditory stimuli, memory, and speech
