3. Our Divided Brains Corpus Callosum large bundle of neural fibers connecting the two hemispheres

4. Brain Lateralization Right hemisphere controls left side of body and visual field Left hemisphere controls right side of body and visual field

5. BRAINSTEM  Heart rate and breathing CEREBELLUM  Coordination and balance Other Parts of the Brain amygdala pituitary hippocampus THALAMUS  Relays messages

6. The Thalamus –the brain’s sensory switchboard, located on top of the brainstem –directs messages to the sensory receiving areas in the cortex and transmits replies to the cerebellum and medulla

7. The Cerebellum –helps coordinate voluntary movement and balance

8. The Lower Brain Brainstem –responsible for automatic survival functions Medulla –controls heartbeat and breathing Pons –Regulates brain during sleep

9. Reticular Activating System Keeps us alert or puts us to sleep – alcohol mimics reticular system neurons Most drunk driving accidents are due to drivers falling asleep at the wheel

12. Recap of Mid Brain and Lower Brain Brain stem: internal physical state of body Medulla Oblongata: breathing, heartbeat Pons: regulates brain during sleep Thalamus: relay station between senses and cerebral cortex Cerebellum: balance and movement Limbic system: emotions, memory Hippocampus: long term memory Amygdala: emotion, fear, aggression, motives, (very active during adolescence) Hypothalamus: eating, drinking, body temperature
