  1. Sympathetic – (stimulate) ( fight of flight”) (accelerator) Parasympathetic (pacify) (rest and digest) (brake) p. 62

  2. PARTS OF THE BRAIN

  3. FOREBRAIN

  4. CEREBRAL CORTEX • THE OUTERMOST LAYER OF THE CEREBRUM COMPOSED OF BILLIONS OF CELLS • DEEP FOLDS GIVE IT A LARGE SURFACE, ALLOWING OUR BRAIN TO CONTAIN A LARGE NUMBER OF NEURONS AND STILL FIT IN OUR SKULL

  5. CORPUS CALLOSUM • MILLIONS OF NERVE FIBERS THAT CONNECT THE TWO HEMISPHERES • MESSAGES ARE SENT CONTINUALLY BACK AND FORTH

  6. BROCA’S AREA – FRONTAL LOBE AREA WHICH FOCUSES ON SAYING SENTENCES WERNICKE’S AREA – TEMPORAL LOBE AREA WHICH FOCUSES ON CREATING SENTENCES

  7. BROCA’S AREA IF ITS BROKA, YOU WON’T TALKA WERNICKE’S AREA- WORDS MAKE NO SENSE – LIKE A WORD SALAD p. 81-82

  8. FRONTAL LOBE • INVOLVED WITH COGNITIVE ACTIVITIES SUCH AS PLANNING, DECIDING, AND PURSUING GOALS • MOTOR CORTEX(STRIP) IS IN THE FRONTAL LOBE AND CONTROLS THE ACTIONS OF MORE THAN 600 VOLUNTARY MUSCLES

  9. PARIETAL LOBE • CONTROLS INCOMING SENSORY INFORMATION • SENSORY STRIP(CORTEX) IS LOCATED IN THIS LOBE AND PROCESSES INFORMATION ABOUT TEMPERATURE, TOUCH, BODY POSITION, AND PAIN

  10. OCCIPITAL LOBE • LOCATED IN THE BACK OF THE HEAD AND IS THE MAJOR DESTINATION FOR VISUAL INFORMATION

  11. TEMPORAL LOBE • LOCATED AT THE SIDE OF EACH HEMISPHERE AND IS WHERE AUDITORY (HEARING) IS PROCESSED. • CONTAINS SOME CENTERS FOR SPEECH IN THE LEFT TEMPORAL LOBE

  12. THALAMUS • BULGE AT THE TOP OF THE BRAIN STEM THAT FUNCTIONS AS THE BRAIN’S RELAY STATION FOR INCOMING AND OUTGOING MESSAGES FROM THE BRAIN TO THE BODY AND THE BODY TO THE BRAIN

  13. HYPOTHALAMUS • ONE OF THE SMALLEST STRUCTURES OF THE BRAIN (ABOUT THE SIZE OF A PEARL) • REGULATES PHYSIOLOGICAL PROCESSES SUCH AS HUNGER, THIRST, PLEASURE, FEAR, ANGER, SEXUAL AROUSAL, AND TEMPERATURE

  14. HYPOTHALAMUS • THE HYPOTHALAMUS MAINTAINS THE BODY’S INTERNAL BALANCE-HOMEOSTASIS (LITERALLY MEANS STAYING THE SAME)

  15. LIMBIC SYSTEM

  16. LIMBIC SYSTEM • HIPPOCAMPUS-ASSOCIATED WITH MEMORY, LEARNING, AND EMOTION • AMYGDALA-PLAYS A KEY ROLE IN AGGRESSION. ALSO INVOLVED IN MEMORY AND EMOTION

  17. MIDBRAIN • UPPER PORTION OF THE BRAIN STEM • CONTAINS CENTERS FOR RECEIVING AND INTEGRATING SEVERAL TYPES OF SENSORY INFORMATION • BRAIN STEM REFERS TO THE AREA OF THE BRAIN BELOW THE CEREBRUM

  18. HINDBRAIN • CEREBELLUM COORDINATES INFORMATION FROM THE SPINAL CORD AND OTHER PARTS OF THE BRAIN TO MAKE MOVEMENTS, MAINTAIN BALANCE AND EQUILIBRIUM ALSO HELPS US TO GET TO OUR DESTINATION

  19. PONS RELAYS MESSAGES WITHIN THE BRAIN AND THE SPINAL CORD ALSO HELPS CONTROL BREATHING • MEDULLA (OBLONGATA) CENTER FOR BREATHING AND BEATING OF THE HEART BASIC FUNCTIONS FOR SURVIVAL

  20. RETICULAR ACTIVATING SYSTEM (RAS) RETICULAR FORMATION- REGULATES THE SLEEP-WAKE CYCLE AND LEVELS OF AROUSAL AND ACTIVITY WHILE AWAKE DAMAGE TO THE RAS MAY RESULT IN PROLONGED SLEEP DESTRUCTION OF THE RAS MAY RESULT IN A COMA

  21. THALAMUS • RECEIVES ALL SENSATIONS EXCEPT SMELL • RELAY STATION BETWEEN LOWER BRAIN CENTERS AND CEREBRAL CORTEX

  22. HYPOTHALAMUS • GOAL ORIENTED BEHAVIOR: • 4 Fs • FEEDING • FLEEING • FIGHTING • MATING

  23. HEMISPHERES OF THE BRAIN

  24. HEMISPHERES WORK TOGETHER FOR ALMOST EVERY TASK THE SPECIALIZATION THAT EACH HEMISPHERE POSSESSES MAKES IT EASIER FOR BOTH SIDES TO WORK TOGETHER
