No PowerPoint, please! |
 ...tudied, again, the effects Microsoft PowerPoint has on viewers of presentations made with the help of this software.
The Australian scientists think that according to the "cognitive load theory" the human brain cannot receive and 'decode' visual and audio information at the same time for longer than a few seconds. Thus information consisting of diagrams and graphs accompanied by speech would be perceived easily; neverthe... |

As a matter of fact, it is now a scientific fact, as results of a research of the European laboratory for molecular biology in Heidelberg show that the human brain and the entire human nervous system finds its roots in the most primitive creatures - such as worms and insects.
The human brain has always been a very attractive object for research for almost any area of scie... |

Computer the Size of a Molecule Imitates Brain Work |
 ... Scientists created a device that is not larger than a few molecules and that is claimed to mimic how the most complicated computer – human brain works.
The computer can perform 16 times more operations than a common computer transistor. Researchers expect the device to complete even 1,000 times more operations.
The tiny computer is made of a duroquinone, a molecule looking like a hexagonal plate with four cone... |

Our Brain Enjoys More When Music is Played Live by a Musician rather than a Computer |
 ...ains react to the performance of other individuals," mentioned Dr. Koelsch.
During the study the researchers were also able to discover that when a classic composition was played by a real musician, human brain was more likely to search for musical meaning.
"This is similar to the response we see when the brain is responding to language and working out what the words mean. Our results suggest that musicians actually tel... |

New Technologies Show the Complex Structure of the Brain |
 ...A usual scanning of a human brain presents a muted gray image, which one can distinguish quite easy by a series of complex folds. However, a neuroscientist working at Massachusetts General Hospital, in Boston, Van Wedeen, claims that such image is only a shadow of the actual brain. Recently scientists revealed the real structure of our brain, featuring accurately ordered tangle of nerve cells and the elongated projections... |

World's First Robot With a Biological Brain |
 ...bout 24 hours, they start sending out feelers to each other and making connections. Within a week we get some spontaneous firings and brain-like activity" which happens just like in a standard rat or human brain, said Warwick. However, he added that the brain requires external stimulation, because it may dry up and die in just a few months.
At a certain degree Gordon learns by itself. For example when he hits a wall, ... |

Scientists Discovered a Monogamy Gene in Men |
 ...stood how the variations of RS3 334 gene work to affect commitment and bonding. Earlier it was discovered that RS3 334 gene section was linked to the feeling of trust, evoking the response in part of human brain amygdalas. Another connection of this gene with social behavior was found in a study on autism, with multiple copies of RS3 334 contributing to this disorder.

Deaf People Can Feel Their Speech, Scientists Say |
 ...University in Montreal, Canada. Together with his colleague, Sazzad Nasir, Ostry headed the research.
The majority of neuroscientists, who make their research on speech, try to focus on the way the human brain learns from different sounds to correct for errors. Ostry mentioned that people feel when they speak right or wrong.
In order to part this ability from learning by hearing, the two scientists sought help of five... |

Scientists Observed the Transformation of Speech into Song When Repeated |
 ...A psychologist from the University of California in San Diego revealed that when a spoken phrase is repeated, it somehow transforms into a song or at least that is how human brain perceives.
For the first time Diana Deutsch noticed such illusion when, back in 1990s, she revised a recording of her own voice. She noted that the phrase "sometimes behaves so strangely" somehow morphed into a song when it was repeated severa... |
