Questions and Answers

What type of memory is NREM sleep good for, according to the text?

  • Emotional memory
  • Procedural memory
  • Working memory
  • Declarative and semantic memory (correct)

    • What does slow wave sleep during NREM do to calcium channels?

  • Inhibits type N calcium channels to prevent synaptic overactivity
  • Opens type T calcium channels for the release of enzymes promoting synapse growth (correct)
  • Closes type T calcium channels to conserve energy
  • Activates type L calcium channels for neurotransmitter release

    • How does synchronized firing aid in the transference of working memory from the hippocampus to the cortex, according to the text?

  • Facilitates the consolidation of memories within the hippocampus
  • Reduces neural firing between cortical areas
  • Strengthens connections between different brain areas (correct)
  • Enhances the capacity of the hippocampus to hold new memories

    • Which type of memory is identified as being supported by REM sleep, according to the text?

    What evidence is provided in the text regarding the relationship between synchronized firing and the transference of working memory from the hippocampus to the cortex?

    <p>Synchronized firing strengthens the connections between different brain areas, allowing for the memory to move from MTL to cortex.</p> Signup and view all the answers

    Why is it suggested that sleep states may not have evolved from more primitive quiescent states?

    <p>The diversity of sleep states across different species suggests that sleep has adapted to serve various functions in response to ecological and physiological demands, rather than following a direct linear progression.</p> Signup and view all the answers

    What evidence is provided in the text regarding the relationship between sleep and metabolism?

    <p>There is a decrease in metabolism during sleep, and the amount of time spent asleep varies across animals and species, suggesting a link between sleep and metabolism.</p> Signup and view all the answers

    Did sleep cause the evolution of more complex nervous systems, or was it the other way around?

    <p>There was a mutual influence between sleep and the development of more complex nervous systems.</p> Signup and view all the answers
