9.14, MIT, Spring 2009 Class #3-4 Questions based on lectures and Schneider book chapters: 1) Three basic types of multipurpose actions were described in class. For any mammal you are familiar with, what are two specific examples of each? 2) Define primary sensory neuron, secondary sensory neuron, interneuron, motor neuron. 3) What is the notochord? 4) Amphioxus, the primitive protochordate, has visual inputs. What division of the CNS do these inputs enter? How do we know that there is a probable evolutionary relationship between the visual structures of Amphioxus and structures in mammals? 5) Give examples of the ongoing background support, provided by actions of the nervous system, for what we call motivated behavior patterns and for various cognitive functions. 6) Give an example of a sensory function that has led to great expansions of specific parts of the hindbrain in certain species of fish. 7) What sensory functions led to great expansions of the midbrain in some species? 8) What sensory inputs led to the early expansion of the endbrain, and to the later expansion of the endbrain, prior to the evolution of primates and other large-brained mammals? 9) What closely related brain systems evolved to serve visceral and social needs of animals?
