12.08.2010 - Our brains are wired so we can better hear ourselves speak, new study shows
Like the mute button on the TV remote control, our brains filter out unwanted noise so we can focus on what we’re listening to. But when it comes to following our own speech, a new brain study from the University of California, Berkeley, shows that instead of one homogenous mute button, we have a network of volume settings that can selectively silence and amplify the sounds we make and hear. Activity in the auditory cortex when we speak and listen is amplified in some regions of the brain and muted in others. In this image, the black line represents muting activity when we speak. (Courtesy of Adeen Flinker) Neuroscientists from UC Berkeley, UCSF and Johns Hopkins University tracked the electrical signals emitted from the brains of hospitalized epilepsy patients. Their findings, published today (Dec. 8, 2010) in the Journal of Neuroscience, offer new clues about how we hear ourselves above the noise of our surroundings and monitor what we say.

Less Empathy Toward Outsiders: Brain Differences Reinforce Preferences For Those In Same Social Group An observer feels more empathy for someone in pain when that person is in the same social group, according to new research in the July 1 issue of The Journal of Neuroscience. The study shows that perceiving others in pain activates a part of the brain associated with empathy and emotion more if the observer and the observed are the same race. The findings may show that unconscious prejudices against outside groups exist at a basic level.

Mini-strokes leave 'hidden' brain damage Each year, approximately 150,000 Canadians have a transient ischemic attack (TIA), sometimes known as a mini-stroke. New research published January 28 in Stroke, the journal of the American Heart Association shows these attacks may not be transient at all. They in fact create lasting damage to the brain. The stroke research team, led by Dr. 100 Ways To Become More Conscious: How To Raise Your Consciousness 1. Connect with nature – Go for a walk in the forest, jungle, field of daisies, or wherever you feel like getting a connection with nature. It is possible to feel at deep sense of peace and oneness when you attempt to connect with nature.

Type A and Type B personality theory Type A and Type B personality theory describes two contrasting personality types that could either raise or lower, respectively, one's chances of developing coronary heart disease. There is considerable controversy about the role of these personality types in coronary heart disease and the role of tobacco industry funding of early research in this area. History[edit] Type A personality behavior was first described as a potential risk factor for heart disease in the 1950s by cardiologists Meyer Friedman and Ray Rosenman.

Letter-Color Synaesthesia For as long as I can remember, I've had this implicit sense of a relationship between letters and colors. To me, every letter seems to have a color of its own. When I think of a word, I am aware of its color and the color of its component letters. The phenomenon is consistent enough that I can rely on it to help me remember things like phone numbers and proper names. I call it my letter-color synaesthesia.

Good sleep, good learning, good life Foreword It is everyone's dream to wake up fresh, happy, and ready for action on a daily basis. Sadly, in the modern world, only a small minority lives that dream. Yet the dream is within reach for most healthy people given: a bit of knowledge, and a readiness to make some lifestyle sacrifice. I hope that this article compiles all the basic ingredients of knowledge that are helpful in accomplishing refreshing sleep.

Cognitive Enhancement Versus Drug War Cognitive enhancement is not about future generations playing video games via neural implants and thought interfaces. Presently, it is about a large fraction of the worlds scientist shortening their lives (speak about lifespan enhancement) via caffeine, nicotine, and sugar intake that leads to diabetes and cardio vascular illnesses via hypertension with high blood pressure and heart troubles, teeth grinding, frequent urination, and so on. Coffee is a must at all conferences. No brew, no chance of surviving afternoon talks in a fully conscious state. The irony should be obvious: In a world with Modafinil and methylphenidate and where the cardio-toxic problems from caffeine are well known, exactly those who should know best, the scientists, are collectively ignorant. Why?

Brainwave entrainment Brainwave Entrainment is any practice that aims to cause brainwave frequencies to fall into step with a periodic stimulus having a frequency corresponding to the intended brain-state (for example, to induce sleep), usually attempted with the use of specialized software. It purportedly depends upon a "frequency following" response on the assumption that the human brain has a tendency to change its dominant EEG frequency towards the frequency of a dominant external stimulus.[citation needed] Such a stimulus is often aural, as in the case of binaural or monaural beats and isochronic tones, or else visual, as with a dreamachine, a combination of the two with a mind machine, or even electromagnetic radiation. Hemispheric Synchronization, a potential and generally desired result of brainwave entrainment, refers to a state when the brainwave pattern of the right and left hemispheres become alike. A person with similar activity in both hemispheres is alleged[by whom?]

The fine dopamine line between creativity and schizophrenia New research shows a possible explanation for the link between mental health and creativity. By studying receptors in the brain, researchers at the Swedish medical university Karolinska Institutet have managed to show that the dopamine system in healthy, highly creative people is similar in some respects to that seen in people with schizophrenia. High creative skills have been shown to be somewhat more common in people who have mental illness in the family. Creativity is also linked to a slightly higher risk of schizophrenia and bipolar disorder. Certain psychological traits, such as the ability to make unusual pr bizarre associations are also shared by schizophrenics and healthy, highly creative people.
