Listening to your brain rhythms may improve sleep, memory - CBS News - 0 views

  •  
    With previous research suggesting that the fostering of long term memories happens during sleep (when the brain is in an oscillating rhythm), current research suggests that listening to audio coinciding with that rhythm can increase memory skill. As an experiment, researchers worked with 11 healthy students who were asked to memorize 120 word pairs before going to bed. As a result, on the night that they listened to the rhythm of their brain, they remembered the most words. This study also revealed that synced audio was linked to a longer deep sleep instead of more deep sleep cycles.

Alzheimer's - Alzheimer's Association - 0 views

  • Alzheimer's is a type of dementia that causes problems with memory, thinking and behavior.
  • Alzheimer's disease accounts for 50 to 80 percent of dementia cases.
  • Up to 5 percent of people with the disease have early onset Alzheimer's
  • ...8 more annotations...
  • Each nerve cell connects with many others to form communication networks
  • However, serious memory loss, confusion and other major changes in the way our minds work may be a sign that brain cells are failing.
  • Those with Alzheimer's live an average of eight years after their symptoms become noticeable
  • Keeping everything running requires coordination as well as large amounts of fuel and oxygen
  • Plaques are deposits of a protein fragment called beta-amyloid (BAY-tuh AM-uh-loyd) that build up in the spaces between nerve cells.
  • Tangles are twisted fibers of another protein called tau (rhymes with “wow”) that build up inside cells.
  • It's the destruction and death of nerve cells that causes memory failure, personality changes, problems carrying out daily activities and other symptoms of Alzheimer'
  • Ninety percent of what we know about Alzheimer's has been discovered in the last 15 years

    Alzheimer's is actually a common form of dementia. Roughly 50-80 percent of patients with dementia are associated with Alzheimer's. Alzheimer's is considered a neurological disorder with loss of memory, thinking and behavioral function. Alzheimer's is common diagnosed in patients 65 and older with the exception of patients with Early-Onset Alzheimer's. Alzheimer's progressively worsens over time and commonly culminates in death 8 years after symptoms start to arrive. Again no cure has been found for alzheimer's, but certain medications are used to treat symptoms. A build-up of plaques and tangles in the brain is suspected to kill nerve cells and cause a loss of brain function. The loss of nerve cells causes gaps in the communication network and eventually causes a loss of function in those areas of the brain. Although scientists do not know their exact role in Alzheimer's, patients have been associated with an abundant amount of these abnormal structures.

A Brain for Rhythm | The Scientist Magazine® - 0 views

  •  
    Since the 1920s, researchers have recorded rhythmic patterns or electrical impulses in the brain. Now, rhythm is known to have effects on perception, attention, working memory, learning, and language. Gazzaley, a neuroscientist, wants to determine if these rhythms vary between healthy individuals. He is also interested in exploring what roles these rhythms play in various disorders. In one experiment, Gazzaley worked with the drummer, Mickey Hart, by strapping him to an EEG while playing the drums. Hart's brain was shown on screen, live.

UCSB study reveals that overthinking can be detrimental to human performance - 1 views

  •  
    This article is revealing the facts found from a study done on humans. This study shows that over thinking something can actually cause a person to preform worse at the task. This article also states the differences between the two types of memory. People where asked to think about riding a bike. Most people performed very poorly when it came to the details of riding bike. Only when they where guessing do most perform oaky.

The Mental Preparation of High-Level Athletes - Dana Foundation - 0 views

  •  
    Although physical commitment is required to be successful at a given sport or activity, mental preparation is the key to victory. When individuals are competing at the Olympic level, those competitors have very small physical differences. What separates the winners from the losers is the mental preparation. Practice builds mental strength through memory and confidence; with this strong mentality, competitors are most successful when they let loose and "go with the flow." Letting oneself go in stressful situations or important competitions is crucial because thinking too much can lead to making foolish mistakes from the overwhelming stress a person can put on them self. Once a person starts to focus on one single adjustment, their performance deteriorates. Entering the "flow" state allows a person to perform easily and comfortably without stress. Practice actually betters the brain through the memorization of muscle movements. In order to achieve success, it is essential for one to maintain an alert state of mind. In this, a person is always prepared for what comes next. Keeping calm in important competitions is equally important; practice betters one's ability to do this through hormone and brain chemistry changes. Motivation also affects performance. Only those who have positive mindsets and strong minds are going to win competitions. Sports affect people for the rest of their lives through the mental changes they experience.

Stress can make the brain more susceptible to mental illness - Medical News Today - 0 views

  •  
    The brain has a balance between "gray matter" and "white matter." People suffering from chronic stress tend to have more white matter, which is white tissue with a  myelin coating. Studies have shown that the stem cells in people with chronic stress mature into oligodendrocytes, which produce myelin. As a result, their learning and memory skills are affected because more oligodendrocytes are being produced instead of neurons. It is also believed that stress causes the hippocampus to become strongly connected to the amygdala, weakening the connection to the prefrontal cortex. This means that people with stress disorders have faster fear responses and have bigger responses to stressful situations than they normally would.

Wait, Have I Dreamt This Before? How Is That Possible? | Psychology Today - 0 views

  •  
    In a survey carried out by Dr. Brown, an author, 86% of the participants reported having experiences that they recall from past dreams. Anne Cleary, Ph.D. has three reasons as to why a moment might seem like a re-experience of a dream: forgetting the experience leading to the dream, connections made during sleep, and mistaking the source. Strongly believing that dreams don't just come from "nowhere", Cleary admits to having "deja vu" experiences before.
