20 Questions
What type of memory is NREM sleep good for, according to the text?
Declarative and semantic memory
What does slow wave sleep during NREM do to calcium channels?
Opens type T calcium channels for the release of enzymes promoting synapse growth
How does synchronized firing aid in the transference of working memory from the hippocampus to the cortex, according to the text?
Strengthens connections between different brain areas
Which type of memory is identified as being supported by REM sleep, according to the text?
Perceptual learning
What happens to the level of beta amyloid during deep or slow wave sleep?
It decreases
What type of brain waves are observed during REM sleep?
Sawtooth and theta waves
Why is it mentioned that sleep correlates are not reliable?
They do not apply to all animals
Why could sleep have evolved?
As a way to conserve energy
What evidence is provided in the text regarding the relationship between sleep and metabolism?
There is a decrease in metabolism when we sleep
How does sleep help with cognitive adaptation?
During SWS and REM, there is memory consolidation
What type of memory is NREM sleep good for, according to the text?
Declarative and semantic memory
How does NREM sleep affect Ca channels?
Slow wave sleep opens type T calcium channels, promoting the growth of synapses or number of receptors
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?
Synchronized firing strengthens the connections between different brain areas, allowing for the memory to move from MTL to cortex.
What type of memory is identified as being supported by REM sleep, according to the text?
Perceptual learning
What are the characteristics of brain waves in REM sleep?
Sawtooth and theta waves
Why is it suggested that sleep states may not have evolved from more primitive quiescent states?
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.
What evidence is provided in the text regarding the relationship between sleep and metabolism?
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.
Did sleep cause the evolution of more complex nervous systems, or was it the other way around?
There was a mutual influence between sleep and the development of more complex nervous systems.
What is unique about the sleep pattern of monotremes?
Monotremes undergo REM and NREM sleep at the same time, which is unusual for mammals.
How did REM sleep evolve, and with which animal groups?
REM sleep evolved independently with birds and mammals.
