Exercising Benefits - 0 views

  •  
    This site is another educational site i discovered during my TFAD assignment. It really digs deep into MANY benefits of exercise. If you are wondering what exercise can do for YOU then this is the site to go to for information. It gives you history, examples, the present. All the basic information.

  •  
    *sticky note* Your muscles activate your brain receptors. So knowing that your brain is more active with your muscles, exercising them would be a huge benefit and aid to a better lifestyle
  •  
    *sticky note* Mental exercise for the brain: on an everyday basis our brain is learning a new skill. This uses a lot of power from our brain which requires us EXERCISING our brain physically and mentally ***Example of an exercise you can do whenever you are on the computer: switch the hand you are using to move your mouse. It must feel pretty awkward but it's alright you are exercising movement AND learning a new skill at the same time.
  •  
    *sticky note* If you think sitting behind your computer or TV screen is going to get you smarter... Think again! It really doesn't in fact it affects us in a bad way. Weakens our eyes, and uses so much energy from our brain. Where on the other hand, just walking can benefit us a ton. It helps our blood circulation and the oxygen/glucose that reaches our brain.
  •  
    *sticky note* Exercise improves our memory, helps us remember our studies, wakes up our brain in the morning. Enhances our brain cells, creates higher brain functions. These are just the *few things that exercising does for us. It is quite amazing
  •  
    *sticky note* Exercising also helps our aging process. Exercise fools our brain into thinking we are younger when we begin exercising on a daily basis which could be great for you. Who wouldn't want to feel 40 when they're really 50? I know i would

  • observing and measuring which parts of the teens’ brains are most active
  • During the risk-taking and rewards-based tests, one region deep inside the brain shows more activity in adolescents than it does in children or adults, Crone says. This region, known as the ventral striatum, is often referred to as the “reward center”
  • Adolescents are particularly sensitive and responsive to influence by friends, desires and emotions, researchers say. It’s one of the hallmarks of this stage in life.
  • eel good” response helps explain why they often give in to impulsive desires.

  • brain is locked in a tug-of-war between the logical pull of the prefrontal cortex and the impulsive pull of the ventral striatum.
  • toward years of serious risk-taking
  • prefrontal cortex seems to lag in developing. It turns out this delay serves an important evolutionary function,
  • So it’s important that the master planner not be too rigid or restrictive during adolescence. Instead, it stays open to learning.
  • One of the processes involves axons, or fibers that connect nerve cells. From infancy, these fibers allow one nerve cell to talk to another. Throughout the teen years, fatty tissue starts to insulate the axons from interfering signals — it is a bit like the plastic that coats electrical cables.
  • In axons, the insulating tissue allows information to zip back and forth between brain cells much more quickly. It also helps build networks that link the prefrontal cortex with other brain regions, allowing them to work together more efficiently.
  • The second key process involves synapses. A synapse is like a dock between nerve cells. Nerve cells communicate by transmitting chemical and electrical signals. Those signals move through the synapses.
  • brain starts discarding many of these connections
  • So the brain strengthens the synapses it really needs and eliminates those that either slow things down or aren’t useful.

HMS Press Release - Deciphering the teenage brain - 0 views

  • “Teens are in a discovery mode,” says Frances Jensen, MD, an HMS professor of neurology. “They’re experiencing new things, and their brains are developing accordingly. There’s simply a lot going on in their brains.”
  • The teenage brain matures from back to front. The posterior regions, especially those above the spinal column, are largely responsible for motor control. Their earlier maturation helps account for the quick acquisition of locomotion and other movement skills by young people. Maturation of many sensory regions also occurs early, enabling a growing person to learn from the surrounding world. The maturing of the forward regions of the brain, particularly the frontal lobe, doesn’t occur until late adolescence or early adulthood; some researchers say the region’s maturation may not be complete until age 30.
  • The ease of learning that most teens enjoy, however, can carry a steep cost: addiction. “The brain builds itself as it responds to experiences,” Jensen says. “With teens who experiment with drugs, this can result in addiction. It’s the same pattern as learning—we want more, more, more.”
  • ...1 more annotation...
  • The challenge for parents, educators, clinicians and others who deal with teenagers is to determine whether their exasperating behavior is just the stuff of growing up or whether their moodiness and lack of judgment are indicative of a larger, perhaps pathological, problem. Many mental disorders begin to manifest during adolescence, including schizophrenia, anxiety, depression, eating disorders, and drug and alcohol abuse. “The key,” says Jensen, “is to be aware of what’s going on with your kids. Teens today are exposed to more stress than ever before, including drugs, alcohol, and violence. We all have to be mindful.”
  •  
    This article was written by Scott Edwards of Harvard Medical School on the intricacies of the teen brain and what exactly is going on pertaining to the brain during adolescence. It states that throughout adolescence teens go through many drastic changes. Consequently, this development of the brain may not even be completely finished until the age of 30 in certain cases. It essentially gives the how and why to the volatile behavior that most teenagers acquire.

  • The human brain can only hold about seven pieces of information for less than 30 seconds, which means, your brain can only handle a 7-digit phone number
  • omething interesting and relevant needs to happen in a lecture or presentation every 10 minutes so that the audience pays attention and remembers what you say

  • Getting these methods right is crucial, as pressure mounts to use them in medical decisions, including whether or not to terminate life support, and in the legal battles that sometimes ensue. There are a number of ongoing legal cases in Canada that involve vegetative or minimally conscious patients and end of life decisions, says Adrian Owen, a neuroscientist at the University of Western Ontario. “I’m absolutely sure fMRI is going to play a role in one or more of these cases in the next 12 months.”

      This website is very interesting because it explains that their is an architectural difference in the brain of a psychopath compared to a healthy brain. The areas that are different are the amygdala, which is associated with emotions, fear and agression, and the oribitofrontal cortex (OFC), which is responsible for the decision making. There is white matter that connects the amygdala and the OFC, which is called uncinate fasciculus (UF). They found a significant reduction in the integrity of the small particles that compose the UF of psychopaths compared to control groups of people with the same age and IQ. The degree of abnormality was significantly related to the degree of psychopathy.

      A very popular study (nearly 50,000 young Swedish soldiers were followed for 15 years) showed that those who smoked marijuana at least once were more than twice as likely to develop schizophrenia as those who had never smoked marijuana.

      It was shown that the heaviest users (used more than 50 times) were 6 times more likely to become schizophrenic than the nonsmokers.

      Research on the association of marijuana and the brain is in a very early stage (much is still unknown).  THC* contributes to marijuana's psychological and physical effects.

      One of the many things that are still unknown is how marijuana might lead to psychosis.  There is a theory that marijuana interferes with brain development during adolescence and young adulthood, but this theory is yet to be determined.

      Although many things are still unknown about the relation between the adolescent brain and marijuana, one this is certain: As a teen, by smoking marijuana, you are increasing your vulnerability to psychotic thinking.
  • risk for later schizophrenia, psychosis
  • regular marijuana use increases the chance that a teenager will develop psychosis
  • increases the risk of developing schizophrenia
  • five times were twice as likely to have developed psychosis over the next 10 years
  • smoked marijuana at least
  • hasten the onset of psychosis by three years
  • already have a mother, father, or sibling with schizophrenia
  • most at risk are youths
  • some other psychotic disorde
  • one in five chance
  • even if they never smoke pot
  • one in 10 chance of developing the condition
  • doubles their risk
  • 7 in 1,000 chance
  • 14 in 1,000.
  • possible link between marijuana use and psychosis
  • smoked marijuana at least once were more than twice as likely to develop schizophrenia as those who had never smoked pot
  • marijuana use might lead to psychosis
  • cigarette smoking and lung cancer
  • marijuana and the brain
  • stimulates the brain and triggers other chemical reactions that contribute to the drug’s psychological and physical effects
  • six times as likely to develop schizophrenia as the nonsmokers
  • not clear
  • theory
  • marijuana may interfere with normal brain development during the teenage years
  • young adulthood.
  • increase a young person’s vulnerability to psychotic thinking
  • reward of a short-time high isn’t worth the long-term risk of psychosis or a disabling disorder like schizophrenia.

  • The subjects rate whether the picture is a moral violation on a scale of 1 to 5. Kiehl says most psychopaths do not differ from normal subjects in the way they rate the photos: Both psychopaths and the average person rank the KKK with a burning cross as a moral violation. But there's a key difference: Psychopaths' brains behave differently from that of a nonpsychopathic person. When a normal person sees a morally objectionable photo, his limbic system lights up. This is what Kiehl calls the "emotional circuit," involving the orbital cortex above the eyes and the amygdala deep in the brain. But Kiehl says when psychopaths like Dugan see the KKK picture, their emotional circuit does not engage in the same way.

      Look back on notes taken during documentary on the Brain, similar information and tests
  • He notes that alcoholics have brain abnormalities. Do we give them a pass if they kill someone while driving drunk?
  • Neuroscience and neuroimaging is going to change the whole philosophy about how we punish and how we decide who to incapacitate and how we decide how to deal with people
  • Just like DNA, he believes brain scans will eventually be standard fare. And that, he and others say, could upend our notions of culpability, crime and punishment.

      This articles is very intriguing and similar to a part of the Brain documentary... This website seems credible because their is no advertisement, this is a well known new station and it is partners with pbs, which is a reliable source when it comes to news stories. This website is also very easy to contact.

      Trying to find ways to help children living in poverty

      Not all children living in poverty grow up with physical or mental problems.

    This article was very interesting to read because it proved that poverty does affect a child brain and I love that they are trying to find a way to make sure these children aren't terribly affected in the future.

The cognitive benefits of play: Effects on the learning brain - 0 views

  • In 1964, Marion Diamond and her colleagues published an exciting paper about brain growth in rats. The neuroscientists had conducted a landmark experiment, raising some rats in boring, solitary confinement and others in exciting, toy-filled colonies.
    • Zach Fenlon
       
      This is very interesting because it proves the research that i found for my project but with new studies. It is also amazing to see that this topic has been researched since the 60s.
  • the “enriched” rats had thicker cerebral cortices than did the “impoverished” rats (Diamond et al 1964).
  • rats raised stimulating environments had bigger brains.
    • Zach Fenlon
       
      I wasn't aware that play could affect even the size of the brain, even though it is rats and not humans. I was always under the impression that the brain doesn't change sizes once it has reached it's adult state.

  • Several experimental studies show that school kids pay more attention to academics after they’ve had recess
  • Note that physical education classes are not effective substitutes for free playtime
    • Zach Fenlon
       
      This means that the affects of organized play are not as valuable as free play. 
  • To reap all the benefits of play, a play break must be truly playful.
  • when kids pretend together—“results in improved performances in both cognitive-linguistic and social affective domains.”
    • Zach Fenlon
       
      this is exactly what i discussed in my project. 
  • Some research suggests that the way kids play contributes to their ability to solve divergent problems.
  • The results? Kids given divergent play materials performed better on divergent problems. They also showed more creativity in their attempts to solve the problems (Pepler and Ross 1981).
  • Researchers found that the complexity of block play predicted kids’ mathematics achievements in high school.
    • Zach Fenlon
       
      I didn't realize that studies have identified what play affects what skills. 
  • The association between block play and math performance remained even after researchers controlled for a child’s IQ. It therefore seems plausible that block play itself influenced the cognitive development of these kids.

    This link was very interesting because it specified new elements of how play affects the play, even what types of play.
