  1. The Brain

  2. History • Phrenology • Franz Joseph Gall

  3. Parts of the Brain

  4. Parts of the Brain

  5. The Brainstem • Midbrain • Pons • Medulla • Reticular Formation

  6. The Brainstem • Midbrain • Pons • Medulla • Reticular Formation • Respiration • Cardiovascular fxn • Digestion • Alertness • Sleep patterns

  7. The Brainstem • Midbrain • Pons • Medulla • Autonomic funx • Brain-spinal cord • Coordinate body movements • Reticular Formation

  8. The Brainstem • Midbrain • Pons • Autonomic funx • Arousal • Relay info • Sleep • Medulla • Reticular Formation

  9. The Brainstem • Midbrain • Sight • Eye movement • Body movement • Pupil dilation • hearing • Pons • Medulla • Reticular Formation

  10. The Brainstem • Midbrain • Pons • Medulla • Reticular Formation = BASIC FUNCTIONS!!!

  11. Limbic System

  12. Limbic System

  13. Limbic System • Amygdala – emotion and memory “panic” • CingulateGyrus – regulation of aggression • Fornix – connects hippicampus and hypothalamus • Hippocampus – memory “tagger” • Hypothalamus – waking, adrenaline, emotion, pleasure • Olfactory Cortex – smells • Thalamus – “switchboard” sensory signals between spinal cord and cerebrum

  15. Parts of the Brain

  16. Frontal Lobe Frontal Association Area Frontal Lobe • Judge, plan, reason, organize, problem solve • Attention, personality, behavior and emotions • “higher cognitive functions” PHINEAS GAGE ** intact memory, high on intelligence tests, can perform a task. Can’t plan ahead to BEGIN the task. ** altered personality and removed inhibitions

  17. Parietal Lobe • R – Visuo-spatial • L – Language • Sensory Strip

  18. Temporal Lobe • Left • Speech perception • Verbal and visual memory • Right • Face recognition • Musical ability BOTH - auditory perception - putting objects into groups

  19. Occipital Lobe • Visual Perception

  20. Cerebellum • Balance, movement, coordination
