1. Introduction to Psychology Class 9: Neuroscience 2 Myers: 52-62 June 26, ’06

2. Evolution of the Brain Reptilian  Paleomammalian  Neomammalian

3. The Cerebral Cortex

4.  Frontal (Forehead to top)  Motor Cortex  Parietal (Top to rear)  Sensory Cortex  Occipital (Back)  Visual Cortex  Temporal (Above ears)  Auditory Cortex

5. Motor/Sensory Cortex  Contra-lateral  Inverted “homunculus”  Unequal representation

6. Language Areas  Broca’s Area - Expression - Motor aphasia  Wernicke’s Area - Comprehension - Sensory aphasia LEFT HEMISPHERE FILM: THE MIND: MODULE 8

7. Aphasias  Motor (telegraphic speech): "Yes... ah... Monday... er... Dad and Peter H... (his own name), and Dad.... er... hospital... and ah... Wednesday... Wednesday, nine o'clock... and oh... Thursday... ten o'clock, ah doctors... two... an' doctors... and er... teeth... yah.“  Sensory (word salad): “ I called my mother on the television and did not understand the door. It was too breakfast, but they came from far to near. My mother is not too old for me to be young. Word salad”

8. Brain Plasticity  The brain’s capacity for modification of functioning  Shown by re-organization of pre- wiring  Examples: Removal of hemisphere, blindfolding study FILM: THE BRAIN - DVD 1 - MODULE 10

9. Split-Brains  Epilepsy and the corpus callosum  Hemispheric specialization - Left hemisphere  Logical, sequential, words/numbers, verbal/controls speech - Right hemisphere  Intuitive, expressive, shapes/music/faces, non-verbal FILM: SCIENTIFIC AMERICAN - DVD 1 - SEGMENT 7
