9.14, MIT, Spring 2008 Class #9-12 Below are many questions based on the Schneider chapters and on lectures. Questions numbered 47-63 will be covered in class sessions 9-12. The first 46 questions are for review, and can be answered from earlier lectures and Schneider chapters. Many of these questions are answered in the other readings as well. 1. The forebrain probably expanded in evolution initially because of the importance of _________________________________. 2. Give an example of a “correlation center” that evolved as a connection between sensory analyzers and motor control mechanisms. 3. What are the “distance receptors”? What sense allows an animal to detect certain things that occurred earlier in time? Can you do this? 4. Give two examples of human “fixed action patterns” (FAPs, so named by ethologists). 5. Are the animals with the largest brains the most intelligent animals? What other factors influence brain size? 6. Name two animals with brains larger than the human brain. 7. What are two unique characteristics of the chordate phylum, one mesodermal and one ectodermal. (This phylum includes all vertebrates.) 8. Distinguish the terms “phylogeny” and “ontogeny”. 9. Give three examples of sensory specializations in particular species of vertebrates, specializations that include expanded representations in the CNS. 10. What are two additional behavioral specializations, in primates, that include expanded control areas in the CNS.

9.14, MIT, Spring 2008 Class #9-12 11. The first "Shmoo" CNS diagrams (Shmoo 1) depict a putative pre-mammalian brain. Such a brain is shown without a ______________________, an endbrain structure characteristic of all mammals. 12. In what two major divisions of the mammalian brain are the fluid-filled ventricles the largest? 13. Give a simple definition for the following terms: primary sensory neuron, secondary sensory neuron, motor neuron. 14. In what sense is a primary sensory neuron in the olfactory system the most primitive type of mammalian primary sensory neuron? 15. Define "dermatome". Describe a typical thoracic dermatome. 16. Describe the area of the body surface rostral to the dermatomes for the spinal nerves. What innervates this region? 17. Name three types of channels of conduction for sensory information entering the CNS. 18. Describe the behavior of an animal which has had the forebrain removed. (What behavior is the most normal, and what is the most abnormal?) Note some differences between different species in which this has been done. 19. Why are some animals more helpless after neocortex ablation than others? 20. What is "spinal shock" and why is it so different in widely different species? 21. "Diaschisis", or deafferentation depression, has a specific meaning in neurology, but is a
