      Newborns could learn while sleeping. How do they learn while sleeping? How do they figure that out? How come sleeping adults can't do that, since adults are more developed?

      They tested the newborns by the repeating tones. Could they test other things to figure out how newborns learn while sleeping? How do they know if they aren't just dreaming instead of learning?
  • After about 20 minutes, 24 of the 26 babies squeezed their eyelids together when the tone was sounded without the puff of air.
  • The brain waves of the 24 infants were found to change, providing a neural measurement of memory updating.

      So brainwaves detect memory updating.
  • While past studies find this type of learning can occur in infants who are awake, this is the first study to document it in their most frequent state, while they are asleep

      Infants learn while their awake but can also be found while they are asleep.
  • Learned eyelid movement reflects the normal functioning of the circuitry in the cerebellum, a neural structure at the base of the brain. This study's method potentially offers a unique non-invasive tool for early identification of infants with atypical cerebellar structure, who are potentially at risk for a range of developmental disorders, including autism and dyslexia, she said.
  • Newborn infants' sleep patterns are quite different than those of older children or adults in that they show more active sleep where heart and breathing rates are very changeable," she said. "It may be this sleep state is more amenable to experiencing the world in a way that facilitates learning."
  • Another factor is that infants' brains have greater neural plasticity, which is the ability for the neural connections to be changed

  • •Those who slept longer at night had lower body mass index (BMI), based on weight and height, than those sleeping less.

      So youre telling me the exact opposite of what I've been taught. That sleeping actually helps LOWER the chance of obesity?
  • •For twins averaging more than nine hours of sleep, genetic factors accounted for about 32% of weight variations; for those sleeping less than seven hours, genetic factors accounted for 70% of weight variations. For those sleeping seven to nine hours, 60% of the variation was due to genetic factors. Other factors that affect BMI include environmental ones.

      Okay, that is a hugeeee percentage difference.

    I could write about this. Many teenagers don't sleep enough because of videogames, homework, etc. so it might attract attention.

    I wonder how some people cannot dream.
  • Gracie Biedenstein on 02 Nov 12
     
    I agree with the statement, "If you go to bed with a troubling thought, you may wake with a solution, or at least feel better about the situation.". I feel like if I have a problem after dreaming about what could go wrong and sleeping I feel much better about the situation.
