Questions and Answers

What is the role of the primate cerebral cortex in coordinating behaviors?

  • Operating the spinal cord circuitry system
  • Receiving sensory input
  • Converting sensation to action with greater flexibility (correct)
  • Executing rapid, automatic sensory-to-motor transformations

    • What distinguishes higher mammals such as primates in terms of sensory-to-motor transformation?

  • Using the cortex to convert sensation to action with much greater flexibility (correct)
  • Relying on rapid, automatic sensory-to-motor transformations
  • Reliance on spinal cord circuits for sensory-to-motor transformation
  • Dependence on cognitive content for sensory-to-motor transformation

    • What was the result of Phineas Gage's accident involving a metal rod impaling his brain?

  • Suffered severe pain and loss of vision
  • Experienced temporary paralysis and speech impairment
  • Did not survive the accident
  • Survived with little pain and normal pulse and vision (correct)
