  1. September 17, 2013 Agenda: Review Chapter 3 Intro Nervous System Lab Parts of the Brain Watch Awakenings Table of Contents: 24. Nervous System Lab/Phineas Gage 25. Chapter 3 Graphic Organizer 26. Parts of the Brain 27. Awakenings Notes

  2. Frontal Lobe Summarize our discussion last week of the role of the limbic system and the frontal lobe. • What happened in the frontal lobe of Joel Rifkin? • What happened when Phineas Gage’s frontal lobe was damaged?

  3. Frontal Lobe Video Clips • Phineas Gage- injury to the frontal lobe caused a dramatic personality change • Lobotomy- common psychiatric procedure where the front lobe is intentionally damaged in an attempt to change behavior. Very popular in the US through the 1950’s

  4. Chapter 3 Graphic Organizer Central Nervous System Nervous System Spinal Cord Brain Peripheral Nervous System Hindbrain Midbrain Forebrain

  5. Nervous System Lab- How easy is it to “trick” your brain? You need: A partner Two “sticks” A rule

  6. Parts of the Brain • Hindbrain • Midbrain • Forebrain

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

  8. Hindbrain • Medulla – vital functions (heart rate, breathing, blood pressure) • Pons – regulates body movement; attention, sleep and alertness • Cerebellum – “little brain”; under cerebrum; balance and coordination

  9. Midbrain • Structures that regulate vision and hearing • R.A.S. (Reticular Activating System) – attention, sleep, and arousal; starts in hindbrain and goes through midbrain to bottom of forebrain

  10. Forebrain • Thalamus – “inner chamber”; relay station and sensory switchboard • Hypothalamus – “under” the thalamus; body regulations – temperature, hunger, thirst, sex • Limbic system – structures involved in memory, learning, emotions, aggression, and fear • Cerebrum – “brain”; 70% of brain’s weight; cortex is Latin for “bark”; HIGHER functions/thinking • Association Areas – part of cerebrum – pulls ALL information together; integrates or associates sensory information with stored information

  11. Hemispheres • Left and Right connected by Corpus Callosum • Right is creative/abstract • Left is logical and language based

  12. Lobes Frontal – motor cortex in back Parietal – sensory cortex in front Occipital – visual cortex Temporal – auditory cortex
