Creativity and the Aging Brain | Psychology Today Blogs - 0 views

  • So instead of promoting retirement at age 65, perhaps we as a society should be promoting transition at age 65: transition into a creative field where our growing resource of individuals with aging brains can preserve their wisdom in culturally-valued works of art, music, or writing.
  • Numerous studies suggest that highly creative individuals also employ a broadened rather than focused state of attention. This state of widened attention allows the individual to have disparate bits of information in mind at the same time. Combining remote bits of information is the hallmark of the creative idea.
  • Other studies show that certain areas of the prefrontal cortex involved in self-conscious awareness and emotions are thinner in the aging brain. This may correlate with the diminished need to please and impress others, which is a notable characteristic of both aging individuals and creative luminaries.

  • Finally, intelligence studies indicate that older individuals have access to an increasing store of knowledge gained over a lifetime of learning and experience. Combining bits of knowledge into novel and original ideas is what the creative brain is all about.
  •  
    The aging brain resembles the creative brain in several ways. For instance, the aging brain is more distractible and somewhat more disinhibited than the younger brain (so is the creative brain). Aging brains score better on tests of crystallized IQ (and creative brains use crystallized knowledge to make novel and original associations).

BBC NEWS | Science & Environment | Simulated brain closer to thought - 1 views

  • A detailed simulation of a small region of a brain built molecule by molecule has been constructed and has recreated experimental results from real brains.
  • While many computer simulations have attempted to code in "brain-like" computation or to mimic parts of the nervous systems and brains of a variety of animals, the Blue Brain project was conceived to reverse-engineer mammal brains from real laboratory data and to build up a computer model down to the level of the molecules that make them up.
  • The first phase of the project is now complete; researchers have modeled the neocortical column - a unit of the mammalian brain known as the neocortex which is responsible for higher brain functions and thought.

  • "It starts to learn things and starts to remember things. We can actually see when it retrieves a memory, and where they retrieved it from because we can trace back every activity of every molecule, every cell, every connection and see how the memory was formed."
  • "The next phase is beginning with a 'molecularisation' process: we add in all the molecules and biochemical pathways to move toward gene expression and gene networks. We couldn't do that on our first supercomputer."
  • Organised columns of neurons have been simulated molecule by molecule
  • "This is very interesting research and I'm not criticising it, but it doesn't help us in computer science in having the intelligent behaviour of humans replicated." Professor Markram believes that by building up from one neocortical column to the entire neocortex, the ethereal "emergent properties" that characterise human thought will, step by step, make themselves apparent.

Musicians' brains keep time--With one another: Scientific American Blog - 0 views

  • The researchers found that the guitarists' brain waves were aligned most during three pivotal times: when they were syncing up with a metronome, when they began playing the piece and at points during the composition that demanded the most synchrony.
  • The synchrony was most prominent in the frontal and central parts of the brain that regulate motor function. "Whenever synchrony of behavior was high, synchrony of brain waves were also high,"
  • While brain synchrony during a duet seems like a given, it's a mystery how it happens, says Lindenberger, a psychologist. "One could speculate that this may be related to mirror neurons, the capacity of primates and humans to imagine the action of the other person while performing actions yourself," he says. "The mirror neuron system could be active during synchronized guitar playing."
  •  
    Credit their brain waves: they synchronize before and while musicians play a composition, according to new research.

  • The major finding was that increased working memory capacity following training was associated with changes in brain biochemistry. Specifically, the researchers found changes in the density and binding potential of cortical D1 dopamine receptors in brain regions that are activated during working memory tasks.

10 Big Differences Between Men's and Women's Brains | Masters of Healthcare - 0 views

  •  
    1. Human relationships: Men have a more difficult time understanding emotions that are not explicitly verbalized 2. Left brain vs. both hemispheres: men approach problem-solving from a task-oriented perspective while women more creatively and are more aware of feelings 3.Mathematical abilities: men perform higher 4. Reaction to stress: Men tend to have a "fight or flight" response to stress, women approach it with a tend and befriend strategy. 5. Language. 2 sections of the brain responsible for language - larger in women 6. Emotions. Women are more in touch with their feelings and better able to express them 7. Brain size. Typically, men's brains are 11-12% bigger 8. Pain: women require more morphine to reach the same level of pain reduction. 9. Spatial ability. Men have stronger spatial abilities. 10. Susceptibility to disorders: Men are more apt to have dyslexia or other lang problems. women are more susceptible to mood disorders such as depression and anxiety.

The Strange Neuroscience of Immortality - 0 views

  •  
    "Hayworth has spent much of the past few years in a windowless room carving brains into very thin slices. He is by all accounts a curious man, known for casually saying things like, "The human race is on a beeline to mind uploading: We will preserve a brain, slice it up, simulate it on a computer, and hook it up to a robot body." He wants that brain to be his brain. He wants his 100 billion neurons and more than 100 trillion synapses to be encased in a block of transparent, amber-colored resin-before he dies of natural causes."

How The Brain Rewires Itself - TIME - 1 views

  • What the scientists found was that after a week of practice, the stretch of motor cortex devoted to these finger movements took over surrounding areas like dandelions on a suburban lawn.
  • He extended the experiment by having another group of volunteers merely think about practicing the piano exercise. They played the simple piece of music in their head, holding their hands still while imagining how they would move their fingers. Then they too sat beneath the TMS coil.
  • they glimpsed a revolutionary idea about the brain: the ability of mere thought to alter the physical structure and function of our gray matter. For what the TMS revealed was that the region of motor cortex that controls the piano-playing fingers also expanded in the brains of volunteers who imagined playing the music--just as it had in those who actually played it.

Growing evidence of the brain's plasticity could benefit stroke victims or those suffer... - 1 views

  • With the right training, scientists now know the brain can reshape itself to work around dead and damaged areas, often with dramatic benefits.
  • Therapies that exploit the brain's power to adapt have helped people overcome damage caused by strokes, depression, anxiety and learning disabilities, and may one day replace drugs for some of these conditions.
  • Children with language difficulties have been shown to make significant progress using computer training tools that are the equivalent of cerebral cross-training.
  • ...2 more annotations...
  • Neuroplasticity does not see the different regions of the brain as completely versatile and certainly not interchangeable. But it recognises that if part of the brain is damaged, it can be possible to train other areas to take on, at least to some extent, the job of the lost brain matter.
  • Doidge says he is not anti-medication, but wonders if therapies that tap into neuro-plasticity will soon replace drug treatments for certain conditions. "We can change our brains by sensing, imagining and acting in the world. It's economical and mostly low-tech, and I'm very, very hopeful"

Breakthrough Stanford Research: Hypnotic Trance Changes Brain Activity - 0 views

  •  
    A groundbreaking Stanford Study lead by Dr. David Spiegel has revealed what hypnotists have long known about brain activity whilst under a hypnotic trance. That is: some parts of the brain function differently under hypnosis than during normal consciousness. In essence, hypnosis indeed alters brain patterns and activity. These findings might help explain the intense absorption, lack of self-consciousness and suggestibility that characterize the hypnotic state. Would you like to discover more about Dr. David Spiegel hypnosis research findings and how you can use hypnosis to control pain and increase someone's self-esteem?

Neurophilosophy : Experience induces global reorganization of brain circuitry - 0 views

  • Now referred to as long-term potentiation (LTP), this mechanism has since become the most intensively studied in modern neuroscience,and is widely believed to be the cellular basis of learning and memory, although this is yet to be proven unequivocally.
  • In the new study, Santiago Canals of the Max Planck Institute for Biological Cybernetics in Tübingen and his colleagues used the same protocol to induce LTP. But while the vast majority of researchers have investigated LTP in slices of hippocampal tissue, this study involved observing LTP in live animals.
  • This new research provides the first evidence that the local modifications in synaptic connections induced by LTP lead to long-lasting changes in the activity of a diffuse network of brain regions, and even to facilitated communication between the two hemispheres. The fMRI data showed that hippocampal LTP recruits higher order association areas, as well as regions involved in emotions and others subserving different sensory modalities, all of which are known to be involved in memory formation.

Investing in the Developing Brain : The Frontal Cortex - 2 views

  • But there has been one major payoff from our investigations of the brain: an increasing emphasis on educating young children, before they reach kindergarten. Decades of research have demonstrated that the cortex is astonishingly plastic at a young age and that many important traits and habits seem to solidify before the age of 4.

How To Rewire Your Brain: Neuroscientist Dr. Joe Dispenza Explains - 0 views

  •  
    Dr. Joe Dispenza is a brilliant neuroscientist and author with a knack for demystifying complicated neuroscience. His goal is to show how anyone can use the latest scientific discoveries in neuroplasticity to "rewire" the brain and recondition the body for lasting change. You see, the unconscious mind can't tell the difference between a memory of an event, and the event itself. So when you replay negative thoughts, feelings and memories, the mind reacts as if the event were really happening... ...your heart rate increases, breathing changes and your body goes into a "fight or flight" response (commonly known as stress). Not surprisingly, repeated stress leads to major health problems. But here's the good news: The human mind has an incredible capacity to observe our own thoughts and behaviors, which means you can alter your brain structure by integrating new thoughts and behaviors. Not only that - but you can even change your genetic expression. It isn't always easy... especially when it comes to deeply ingrained habits and addictions. But hypnosis can make it MUCH more likely someone will successfully replace negative thought patterns with positive, healthy new pathways! Intrigued to find out how? Head on over to the Hypnosis Training Academy to listen to Dr. Dispenza's illuminating talk today.
