  1. 1. Introduction to Neuroscience II: From Brain to Behavior Spring 2007
  2. 2. Required text <ul><li>Neuroscience: Exploring the Brain , 3nd ed., by Bear, Connor, and Paradiso; Lippincott Williams & Wilkins, 2001. </li></ul><ul><li>ISBN: 0-7817-3255-7 </li></ul>
  3. 3. Instructors Professor Greene Office: Garland 212 Phone: 3313 Email: ag@uwm.edu Office hours: TR 3:30-4:30 Professor Helmstetter Office: Garland 207 Phone: 4903 Email: [email_address] Office hours: T 1:00-2:00PM
  4. 4. Course policies <ul><li>Prerequisites: Bio Sci 152(p) & 315(c) or Psych 254 </li></ul><ul><li>Lecture schedule </li></ul><ul><li>Exam dates: 2/15; 3/8; 4/17; 5/16 </li></ul><ul><li>Extra credit </li></ul><ul><li>Supplemental material </li></ul>
  5. 5. Neuroscience <ul><li>“ The task of neural science is to explain behavior in terms of the activities of the brain. How does the brain marshal its millions of individual nerve cells to produce behavior, and how are these cells influenced by the environment...? The last frontier of the biological sciences--their ultimate challenge--is to understand the biological basis of consciousness and the mental processes by which we perceive, act, learn, and remember.” — Eric Kandel , Principles of Neural science , fourth edition </li></ul>
  6. 6. Neuroscience Understanding the brain and behavior at different “levels of analysis”. Neuroscientists study the nervous system in a variety of ways.
  7. 7. Fact or Theory
  8. 8. Fact or Theory <ul><li>Theory = understanding </li></ul><ul><li>Theory is not hypothetical </li></ul><ul><li>Facts must be observable (data) </li></ul><ul><li>Theory is broad, fact and hypothesis are narrow </li></ul><ul><li>Theories must be consistent with all available (relevant) facts </li></ul><ul><li>Theory guides the search for fact </li></ul><ul><li>The progress of theory is the purpose of science </li></ul>
  9. 10. Functionalism and Structuralism <ul><li>Functionalism: Emphasizes utility as a causal factor Evolution </li></ul><ul><li>Structuralism: Emphasizes mechanistic understanding </li></ul>
  10. 11. Evolution <ul><li>Variation </li></ul><ul><li>Every species has enormous diversity </li></ul><ul><li>Sexual reproduction insures diversity by recombining genes into new combinations </li></ul><ul><li>Variability allows a species (not an individual) to survive </li></ul>Conch
  11. 12. Evolution <ul><li>Selection </li></ul><ul><li>Selection - reproduction of the fittest </li></ul><ul><li>Differential survival advantage </li></ul><ul><li>Differential reproduction advantage </li></ul><ul><li>Minimal selection pressure after the age of reproduction </li></ul>Tarsier
