3. Major Divisions Left Hemisphere  Logic Right Hemisphere  Creativity Central Core  “Old Brain” Cerebral Cortex  “New Brain”

5. Old Brain New Brain

6. Cerebral Cortex “New Brain” (Higher level cognitive processes) Frontal lobe - Front – Speech, emotion, memory, motor Parietal lobe - Top – Sensory input (skin, etc.) Temporal lobe - Side – Auditory processing Occipital lobe - Back – Vision processing

7. Cerebral Cortex Lobes Cerebellum (not part of Cerebral Cortex)

8. Central Core“Old Brain/Animal Brain” (Basic functions) Cerebellum - Coordination, sensory analysis, (involved with problem solving) Spinal Cord - Communication between brain and body Reticular Formation - Sleep, arousal, and attention Hypothalamus - Regulates temperature, hunger, thirst, Pons - Sleep and arousal Corpus Callosum - Connects the two hemispheres Thalamus - Relay center – coordinates incoming & outgoing Medulla - Regulates unconscious functions

9. Major Structures Cerebral Cortex Pituitary Gland Pons Reticular Formation Spinal Cord Medulla Cerebellum Thalamus Corpus Callousum Hypothalamus

10. Limbic System Primarily responsible for emotions and the formation of memories. Controls Basic Functions:  Emotion  Motivation  Learning (Long-term Memory)  Self-preservation  Aggression  Eating  Reproduction Major Structures:  Amygdala  Hippocampus  Fornix

11. Limbic System (3D Computer Generation)

12. Limbic System (Brain Cross Section)
