PARTS OF THE BRAIN
5
FOREBRAIN
6
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

7
CORPUS CALLOSUM

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

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

15
PARIETAL LOBE

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

16
OCCIPITAL LOBE

• LOCATED IN THE BACK OF THE HEAD AND IS THE MAJOR
  DESTINATION FOR VISUAL INFORMATION

17
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

18
THALAMUS

• BULGE AT THE TOP OF THE BRAIN STEM THAT FUNCTIONS
  AS THE BRAINS RELAY STATION FOR INCOMING AND
  OUTGOING MESSAGES FROM THE BRAIN TO THE BODY AND
  THE BODY TO THE BRAIN

20
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

21
HYPOTHALAMUS

• THE HYPOTHALAMUS MAINTAINS THE BODYS INTERNAL
  BALANCE-HOMEOSTASIS (LITERALLY MEANS
• STAYING THE SAME)

22
LIMBIC SYSTEM
23
LIMBIC SYSTEM

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

26
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

27
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

28

• 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

29

• 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

31
THALAMUS

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

32
HYPOTHALAMUS

• GOAL ORIENTED BEHAVIOR
• 4 Fs
• FEEDING
• FLEEING
• FIGHTING
• MATING

HEMISPHERES OF THE BRAIN
35
HEMISPHERES WORK TOGETHER FOR ALMOST EVERY
TASK THE SPECIALIZATION THAT EACH HEMISPHERE
POSSESSES MAKES IT EASIER FOR BOTH SIDES TO
WORK TOGETHER
