1. The Brain & Behavior

2. Back to the Central Nervous System…brain basics
Appearance
Identify longitudinal, lateral, & central fissures.

9. Brain basics
Size?
The adult human brain weighs about 3 pounds (1,300-1,400 g).
Heaviest ever?
5 lb. 1.1 oz.
The adult human brain is about 2% of the total body weight, but uses 20% of oxygen & blood.
The total surface area of the cerebral cortex is about 2500 sq. cm (~2.5 ft2) .
Smell?
Blue cheese!

11. Hindbrain Spinal cord Medulla: breathing, heart rate, cross-over
Pons: coordinates movement, sleep/dreams
Cerebellum: balance, coordination

12. Hindbrain

13. Midbrain Reticular Activating System (RAS) Arousal: keeps you awake
Alerts the brain

15. Forebrain

16. Forebrain Thalamus: sensory relay center (all except smell)
Hypothalamus: eating, drinking, body temperature, sexual behavior, reward (“pleasure center”), fight or flight; HOMEOSTASIS

19. Forebrain: Limbic system

20. Limbic system Hippocampus: Memory formation
Amygdala: Anger, aggression, & fear

22. Cortex: lobe divisions

24. Motor

25. Sensory

27. Association areas

28. Lobes of the Cerebral Cortex
Directions: For each statement, identify the lobe that has the primary responsibility for that activity or experience.
Frontal Lobe
Parietal Lobe
Occipital Lobe
Temporal Lobe

29. Lobes of the Cerebral CortexD
D. Temporal
