Brain

• The cerebrum controls memory, thinking, planning, speech, and sensation
• The cerebrum is the largest part of the brain and is responsible for higher mental functions such as intelligence, memory, language, and consciousness
• The Brain


  Has 3 main parts
• The 3 main parts of the brain

  • Cerebellum
  • Medulla (or brain stem)
  • Cerebrum
• Cerebellum


  • Controls complex muscle movement
• Medulla (or brain stem)

  • Controls vital activities
• Cerebrum


  • Controls complex thought (largest part of brain)
• The Brain Stem


  The adult brain stem consists of 3 parts: midbrain, pons and medulla
• Brain stem


  • Plays a major role in homeostasis, coordinating movement and conduction of information to higher levels of the brain
  • All axons carrying sensory information towards, and motor instructions away from higher regions of the brain pass through the brain stem
• Cerebellum


  • Plays a major role in coordinating movement and balance
  • Responsible for hand-eye coordination and learning motor skills
• Cerebrum


  In mammals the cerebrum is responsible for information processing
• Cerebrum


  • Responsible for learning, memory, language, reasoning, the voluntary movement of skeletal muscles, and our individual personalities
• Cerebral cortex


  The outer covering of grey matter in each cerebral hemisphere
• Cerebral hemispheres


  The brain is divided into 2 hemispheres
• Left brain


  • Takes care of language, learning mathematics, and logical thinking
• Right brain


  • Takes care of artistic and musical ability, intuition and perception
• Corpus callosum


  Enables the right and left cerebral cortices to communicate
• The 4 lobes of each cerebral hemisphere

  • Frontal
  • Parietal
  • Occipital
  • Temporal
• Frontal lobe


  • Controls movement, speech, intelligence and behaviour
• Parietal lobe


  • Controls sensation, artistic and scientific ability
• Occipital lobe


  • Controls vision
• Temporal lobe


  • Controls hearing, language, taste, smell, memory
