PARTS OF THE BRAIN
FOREBRAIN
     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
    CORPUS CALLOSUM
• MILLIONS OF NERVE FIBERS THAT
  CONNECT THE TWO HEMISPHERES
• MESSAGES ARE SENT CONTINUALLY
  BACK AND FORTH
BROCA’S AREA – FRONTAL LOBE

AREA WHICH FOCUSES ON SAYING
SENTENCES


WERNICKE’S AREA – TEMPORAL LOBE

AREA WHICH FOCUSES ON CREATING
SENTENCES
BROCA’S AREA

IF ITS BROKA, YOU WON’T TALKA

WERNICKE’S AREA-

WORDS MAKE NO SENSE – LIKE A
      WORD SALAD

p. 81-82
       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
       PARIETAL LOBE
• CONTROLS INCOMING SENSORY
  INFORMATION
• SENSORY STRIP(CORTEX) IS
  LOCATED IN THIS LOBE AND
  PROCESSES INFORMATION ABOUT
  TEMPERATURE, TOUCH, BODY
  POSITION, AND PAIN
        OCCIPITAL LOBE
• LOCATED IN THE
  BACK OF THE HEAD
  AND IS THE MAJOR
  DESTINATION FOR
  VISUAL
  INFORMATION
       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
          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
       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
      HYPOTHALAMUS
• THE HYPOTHALAMUS MAINTAINS THE
  BODY’S INTERNAL BALANCE-
  HOMEOSTASIS (LITERALLY MEANS
  STAYING THE SAME)
LIMBIC SYSTEM
       LIMBIC SYSTEM
• HIPPOCAMPUS-ASSOCIATED WITH
  MEMORY, LEARNING, AND EMOTION

• AMYGDALA-PLAYS A KEY ROLE IN
  AGGRESSION. ALSO INVOLVED IN
  MEMORY AND EMOTION
           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
          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
• 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
• 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
         THALAMUS
• RECEIVES ALL SENSATIONS
  EXCEPT
   SMELL

 RELAY STATION BETWEEN
  LOWER BRAIN CENTERS AND
  CEREBRAL CORTEX
         HYPOTHALAMUS
•   GOAL ORIENTED BEHAVIOR:
•   4 Fs
•   FEEDING
•   FLEEING
•   FIGHTING
•   MATING
HEMISPHERES OF THE
      BRAIN
HEMISPHERES WORK TOGETHER FOR
ALMOST EVERY TASK

THE SPECIALIZATION THAT EACH
HEMISPHERE POSSESSES MAKES
IT EASIER FOR BOTH SIDES TO WORK
TOGETHER
