Cerebrum

• CEREBRUM – BRAIN


  -          “seat of consciousness”

  -          responsible for higher mental activities

  -          the largest division of brain

  -          divided into two hemisphere, each of which divided into four lobes

  -          left cerebrum hemisphere, controls the right side of the body

  right cerebrum hemisphere, controls the left side of the body
• LOBES OF CEREBRUM BRAIN

  -          Frontal

  -          Parietal

  -          Occipital

  -          Temporal
• Frontal


  -          plays an integral role in memory function, emotions, decision making/reasoning, and personality

  -          located behind forehead

  -          responsible primarily for thinking, planning, memory, and judgement
• Parietal


  -          plays a major role in senses and integrates sensations, spatial awareness and perception, awareness of body/body parts in space and in relation to each other

  -          located in the middle to the back of the skull

  -          responsible for processing information about taste and touch

  -          receive input from vision

  -          helps identify objects by touch and locate objects in space
• Occipital


  -          located in the very back of the skull

  -          processes visual information

  -          primary function is the processing, integration, interpretation of vision and vision stimuli
• Temporal


  -          located in the sides of the brain

  -          play an integral role in hearing, organizing, comprehension of language, information retrieval (memory and memory formation)

  -          hearing and language
• LOBES OF CEREBRUM BRAIN

  
• LYMBIC SYSTEM


  -          Hippocampus

  -          Amygdala

  -          Hypothalamus
• Hippocampus


  -          seahorse

  -          responsible in changing short term memories into long term memories
• Amygdala


  -          almond

  -          cause aggressive behavior

  -          primary responsible for regulating our perception of and reactions to aggression and fear

  -          memory and emotions

  -          responses to reward and punishment
• Hypothalamus


  -          seat of emotion

  -          maintains homeostasis by regulating some involuntary activities

  -          links the nervous system to the endocrine system via the pituitary gland

  -          regulates body temperature, hunger, thirst and sex

  -         responds to the satisfaction of these needs by creating feelings of pleasure
• LYMBIC SYSTEM

  
• BRAIN STEM


  -          Brain Stem

  -          Thalamus

  -          Reticular Activating Systems

  -          Medulla Oblongata

  -          PONS
• Brain Stem


  -          oldest and innermost region of the brain

  -          wired for survival

  -          designed to control the most basic functions of life

           -          breathing, attention and motor responses

  -          extension of the spinal cord, inclusing the medulla, the pons, and the reticular formation
• Thalamus


  -          found right in top of the midbrain

  -          large bundle of nuclei serves as a relay center of the impulses being sent to the brain areas
• Reticular Activating Systems


  -          controls our level of sleep and arousal

  -          screens out all background information to enable us to sleep

  -          enables us to wake up from sleep
• Medulla Oblongata


  -          regulates the involuntary muscle

  -          medulla, the area of the brain stem that controls heart rate and breathing
• PONS


  -          located in the front of the cerebrum

  -          important to sleep and arousal
