    In this study, audibly recognizable scale-free music was deduced from individual Electroencephalogram (EEG) waveforms. The translation rules include the direct mapping from the period of an EEG waveform to the duration of a note, the logarithmic mapping of the change of average power of EEG to music intensity according to the Fechner's law, and a scale-free based mapping from the amplitude of EEG to music pitch according to the power law.

  • This week, engineer Adam Wilson made global headlines by updating Twitter using his brainwaves. "USING EEG TO SEND TWEET" he explained.
  • Compatible with any PC running Windows, it will ship later this year for $299 (see image). They have shown off a game where the player moves stones to rebuild Stonehenge using mind power alone (see video).
  • Escaping the lab Researchers have developed systems that read brainwaves – in the form of electroencephalogram (EEG) signals – in order to help people suffering from disabilities or paralysis control wheelchairs, play games , or type on a computer. Now, two companies are preparing to market similar devices to mainstream consumers.

  • Californian company NeuroSky has also built a device that can detect emotions: the firm says it can tell whether you are focused, relaxed, afraid or anxious, for example.

  • A Northwestern research group has found that people that solve anagram puzzles by sudden insight rather than by conscious search or analytic strategies have an EEG resting state that prefers the right over the left hemisphere.
  • How often it does seem that it's the highly creative child who is having the greatest struggles in the conventional classroom! It's nice finding research that backs up the association. From this Harvard study, a diffuse attentional style was much more common among individuals with high lifetime levels of creative achievement.
  • The study concludes with a final interesting finding that differences in this attentional style might account for why high IQ beyond a certain point doesn't correlate with higher levels of creative achievement (the threshold effect...e.g. that once one is beyond 120, higher numbers don't correlate with enhanced achievement). If a focused vs. diffuse attentional style is taken into account, then it becomes more evident that diffuse attentional style + high IQ are important factors that contribute to high levels of creative achievement.

  • Davidson's research created a stir among brain scientists when his results suggested that, in the course of meditating for tens of thousands of hours, the monks had actually altered the structure and function of their brains.
  • Lutz asked Ricard to meditate on "unconditional loving-kindness and compassion." He immediately noticed powerful gamma activity - brain waves oscillating at roughly 40 cycles per second -�indicating intensely focused thought. Gamma waves are usually weak and difficult to see. Those emanating from Ricard were easily visible, even in the raw EEG output. Moreover, oscillations from various parts of the cortex were synchronized - a phenomenon that sometimes occurs in patients under anesthesia.
  • The researchers had never seen anything like it. Worried that something might be wrong with their equipment or methods, they brought in more monks, as well as a control group of college students inexperienced in meditation. The monks produced gamma waves that were 30 times as strong as the students'. In addition, larger areas of the meditators' brains were active, particularly in the left prefrontal cortex, the part of the brain responsible for positive emotions.

  • In the traditional view, the brain becomes frozen with the onset of adulthood, after which few new connections form. In the past 20 years, though, scientists have discovered that intensive training can make a difference. For instance, the portion of the brain that corresponds to a string musician's fingering hand grows larger than the part that governs the bow hand - even in musicians who start playing as adults. Davidson's work suggested this potential might extend to emotional centers
  • But Davidson saw something more. The monks had responded to the request to meditate on compassion by generating remarkable brain waves. Perhaps these signals indicated that the meditators had attained an intensely compassionate state of mind. If so, then maybe compassion could be exercised like a muscle; with the right training, people could bulk up their empathy. And if meditation could enhance the brain's ability to produce "attention and affective processes" - emotions, in the technical language of Davidson's study - it might also be used to modify maladaptive emotional responses like depression.
  • Davidson and his team published their findings in the Proceedings of the National Academy of Sciences in November 2004. The research made The Wall Street Journal, and Davidson instantly became a celebrity scientist.
