Newborn infants learn while asleep; Study may lead to later disability tests - 0 views

  • ested the learning abilities of sleeping newborns by repeating tones that were followed by a gentle puff of air to the eyelids.
    • Katie Raborn
       
      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.
    • Katie Raborn
       
      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
    • Katie Raborn
       
      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

Should you listen to music while studying? - University of Phoenix - 1 views

  • Try listening to music without lyrics. Lyrics can be distracting, whereas instrumental music heightens concentration.
  • Try to avoid music that is new. You may find yourself paying closer attention to music that is not familiar.
  • Try to continue one style of studying, such as memorization or math, when listening to a particular type of music.
  •  
    "The scientists drew a link between memory recall to musical tempo. A tempo of 60 beats per minute activates the right hemisphere of the brain, while the material being studied activates the left hemisphere of the brain. With both hemispheres activated, the brain can process information more efficiently."

    "Scientists conducted a series of studies in the 1990s examining the influence of music on memory recall. The research supported the positive effects of background music when studying. The research also suggested that music, especially classical music, heightened arousal and mood, as it reduced blood pressure, heartbeat and stress."

  • In addition to raising the public profile of the disorder, the book also marked the first suggestion that alternate personalities were created as a way to wall off traumatic memories of physical or sexual abuse, and that those memories could be recovered with the help of a therapist.
  • The idea at the time was that the mind locks these memories away, but with the help of a therapist, and through hypnosis or the use of drugs like Sodium Pentothal, these memories could become accessible,
  • Called a “concealed information task,” the test’s goal is ostensibly simple: identify words as they flash on a computer screen. If one of a small set of randomly selected “target” words appears, press yes. For all other words, press no. The catch, McNally said, is that while many of the words hold no meaning for the patients, a small subset of the non-target words are taken from two autobiographical questionnaires patients fill out at the start of the test — one while inhabiting one personality, the second in another.
    • Katie Raborn
       
      They conducted a test and fooled the patients with DID that said that they have no memory of what has happened.
  • When one of those personally relevant words — such as a best friend’s name, favorite food, or favorite sport — appears on screen, McNally said, most patients’ first impulse is to press the yes button. Within moments, however, they realize the word doesn’t appear on the target list, and they eventually give the “correct” answer by pressing no.
  • All participants showed a nearly identical lag for words that were relevant to their alternate personalities, McNally said, suggesting that the information wasn’t locked away in a separate identity.

She was being coaxed to wear the eye-tracking headgear, which consists of two cameras - one that's looking out on the scene to get the baby's perspective, and another that's looking at the eye to track the movement of the pupil. A computer analyzed both camera views to determine exactly where Finn was looking.

But in a room full of toys scattered everywhere and obstacles to climb on and crawl on, the infants only looked toward their mothers about half the time.  And even if they did look at their mothers, they looked at their mothers' faces only about 15 percent of the time.
  • toddlers almost always look directly at the object when reaching for it.
  • Toddlers are able to use information from their peripheral vision and still walk very well.
  • Another interesting finding was that while infants look directly at an obstacle before walking onto or over it, 75 percent of the time they don't always have to.

      The toddlers didn't have to look at the obstacle all the time. they were able to use information for their peripheral vision.

During presentation of the young female personality, the client reported hearing the male alter, which was her primary symptom, along with anxiety and identity dissociation. The client experienced remission of anxiety and hallucinatory symptoms after a month of treatment with perospirone.

      Who would of thought that there would be a concern of human and animals sharing flu's.
  • The first recorded, probable case of fatal human-to-cat transmission of the pandemic H1N1 flu virus occurred in Oregon in 2009, Loehr said. Details were published in Veterinary Pathology, a professional journal. In that instance, a pet owner became severely ill with the flu and had to be hospitalized. While she was still in the hospital, her cat - an indoor cat with no exposure to other sick people, homes or wildlife - also died of pneumonia caused by an H1N1 infection.

  • All of the animals' symptoms were similar to that of humans - they rapidly develop severe respiratory disease, stop eating and some die.
  • "All viruses can mutate, but the influenza virus raises special concern because it can change whole segments of its viral sequence fairly easily," Loehr said.
  • Veterinarians who encounter possible cases of this phenomenon can obtain more information from Loehr or Jessie Trujillo at Iowa State University. They are doing ongoing research to predict, prevent or curtail emergent events.

  • “We worry a lot about zoonoses, the transmission of diseases from animals to people,” said Christiane Loehr, a professor at the OSU College of Veterinary Medicine. “But most people don’t realize that humans can also pass diseases to animals, and this raises questions and concerns about mutations, new viral forms and evolving diseases that may potentially be zoonotic. And, of course, there is concern about the health of the animals.”

      Look at that article.

Functional brain pathways disrupted in children with ADHD - 0 views

  • ADHD is one of the most common childhood disorders, affecting an estimated five to eight percent of school-aged children.

  • ...3 more annotations...
  • Compared to the normal control group, the children with ADHD showed abnormal functional activity in several regions of the brain involved in the processing of visual attention information
  • "What this tells us is that children with ADHD are using partially different functional brain pathways to process this information, which may be caused by impaired white matter pathways involved in visual attention information processing," Dr. Li said.
  • According to the National Institute of Mental Health, there is no single test capable of diagnosing a child with the disorder. As a result, difficult children are often incorrectly labeled with ADHD while other children with the disorder remain undiagnosed.
