  1. Cognitive Neuroscience • What do neurons have to do with cognition? • How can neurons do complex things? • How do we know how the brain works? • What do different areas of the brain do? • Is each part of the brain specialized to do one specific thing?

  2. About Neurons • The nervous system is made up of neurons in the brain, spinal cord, and throughout the body. • Every perception, thought, emotion, and action is related to activity in the nervous system.

  3. A Typical Neuron

  4. Two Neurons Chatting

  5. How Neurons Do Complex Things • Excitation • Inhibition • Convergence • LOTS of neurons (about 180 billion) • Neural circuits • Distributed processing

  6. Studying the Brain Brain Imaging • fMRI - magnetic resonance • PET - radioactive emissions

  7. Studying the Brain • Single-Unit Recording • Event-Related Potentials (ERPs) • Neuropsychology • Testing • Dissociations • Autopsy

  8. Brain Structures • Cerebral Cortex • Occipital Lobes • Parietal Lobes • Frontal Lobes • Temporal Lobes

  9. Lobes of the Cerebrum

  10. The Two Hemispheres • Similar, but not identical in structure or function • Corpus callosum connects the two hemispheres • Right hemisphere controls left side of body, and vice versa

  11. Left Brain-Right Brain • Left Hemisphere specialized for sequential/analytical processing • Right Hemisphere specialized for simultaneous/holistic processing • True for almost all right-handers and many left-handers.

  12. Subcortical Areas

  13. Localization vs. Distributed Processing • Hubel and Wiesel: feature detectors in visual cortex • Prosopagnosiaand the Inferotemporal Cortex • Distributed coding
