Mind Illusions

Do we know what the world looks like?
The eye is made up of some of the most amazing tissue in the body. The lens, for example, is perfectly clear, perfectly curved and is capable of focusing on an incredible amount of data. But vision has only partly to do with the retina, lens, and cornea. Understanding what we see mostly happens in the brain, which is why a person with perfect vision is still susceptible to optical illusions. Do we know what the world looks like? We know approximately what it looks like, which is enough to get by, but our perception of the world is not without a certain amount of 'misreading.' Our visual nervous system approximates color, shape, and dimension.

The process of seeing begins with the presence of light, an image being formed on the retina, and an impulse transmitted to the brain, but there are many other factors that play a part in how we perceive visually. Our perceptions are influenced by our past experiences, imagination, and associations.

Brain Functions


Mozart effect

The Mozart effect can refer to:
  • A set of research results that indicate that listening to Mozart's music may induce a short-term improvement on the performance of certain kinds of mental tasks known as "spatial-temporal reasoning;"
  • Popularized versions of the hypothesis, which suggest that "listening to Mozart makes you smarter", or that early childhood exposure to classical music has a beneficial effect on mental development;
  • A US trademark for a set of commercial recordings and related materials, which are claimed to harness the effect for a variety of purposes. The trademark owner, Don Campbell, Inc., claims benefits far beyond improving spatio-temporal reasoning or raising intelligence, defining the mark as "an inclusive term signifying the transformational powers of music in health, education, and well-being."
The term was first coined by Alfred A. Tomatis who used Mozart's music as the listening stimulus in his work attempting to cure a variety of disorders. The approach has been popularized in a book by Don Campbell, and is based on an experiment published in Nature suggesting that listening to Mozart temporarily boosted scores on one portion of the IQ test. As a result, the Governor of Georgia, Zell Miller, proposed a budget to provide every child born in Georgia with a CD of classical music

Mind Control


Mind control (also known as brainwashing, coercive persuasion, mind abuse, menticide, thought control, or thought reform) refers to a process in which a group or individual "systematically uses unethically manipulative methods to persuade others to conform to the wishes of the manipulator(s), often to the detriment of the person being manipulated". The term has been applied to any tactic, psychological or otherwise, which can be seen as subverting an individual's sense of control over their own thinking, behavior, emotions or decision making. In Propaganda: The Formation of Men's Attitudes, Jacques Ellul maintains that the "principal aims of these psychological methods is to destroy a man's habitual patterns, space, hours, milieu, and so on."
Theories of brainwashing and of mind control were originally developed to explain how totalitarian regimes appeared to succeed in systematically indoctrinating prisoners of war through propaganda and torture techniques. These theories were later expanded and modified to explain a wider range of phenomena, especially conversions to new religious movements (NRMs).

Are Geniuses Born of Made?

For too long we have considered this question and so far no one has given us a concrete answer. Opinions are for everyone. While some have argued that it is possible to produce geniuses in a particular education system, others argue that 80% of intelligence is inherited and 20% is acquired.
U.S. and Australian experts believe they have the answer, after identifying a part of the brain that is stimulated after being "disconnected" and seems to release other functions and creative capacity.
Examples abound in the Internet geniuses, such as Albert Einstein, Mozart, Isaac Newton, etc.. But there are special cases that science has failed to explain as follows:
The Symphony of Marc Yu
Two years sing a song heard at a birthday party and immediately went to the piano and played without a single error. A year later he was playing Beethoven. Now, with seven, is able to remember more than forty pieces and has a perfect pitch that allows you to identify musical notes as colors anyone identifies a capacity that can boast only about 10,000 worldwide fortunate.
But how Marc developed this amazing talent for music? Her mother played music as a baby, are we to do his genius or his gifted brain? Education plays a major role in the development of human intelligence.
Marc counter case which was stimulated from an early age, is Genie Wiley. Genie was born perfectly normal physically. Her father kept her locked up to 13 years of age. Genie had no contact with the world. Not even taught him to eat or go to the bathroom alone. His power, up to 13 years, consisted of baby food, cereal and boiled eggs, all of which were provided to hand him.
In 1970, tired of the abuse and beatings, his mother managed to escape, taking their sons.
Genie is a clear example of the effects of severe isolation in the development phase. In this case not only prevented the development of complete functions of the left hemisphere of the brain and the formation of social interactions, but body movements were very restricted, in a very poor environment as relates to novel stimuli.
If not sufficiently stimulates a child's mind at a crucial stage in its growth fails to develop a relatively normal intellectual capacity.
The idiot savant syndrome

This syndrome occurs in one in 2000 people with mental disabilities. Its origin may be an illness or brain damage occurred before or after birth. The special talent that characterizes it is usually associated with music, mathematics, drawing, painting or a prodigious memory management.
In an article published in Scientific American, American psychiatrists Darold Treffert and Daniel Christensen have for Kim Peek, a 54 year old man with mental retardation, problems with balance and a stunning memory management. Peek reads at a rate of six pages per minute and has memorized over 9000 books of history, sports, movies, geography, astronautics and classical music, among other topics.
Reading the novel The Hunt for Red October by Tom Clancy, it took less than an hour and a half. Four months later he was asked the name of the radio operator of the Russian submarine. Peek said the character's name, described his personality and recited verbatim some passages of the book without mistakes. - Here is the introduction of a documentary about his life -
The Guardian interviewed a very peculiar genius autistic. The boy in question is Daniel Tammet, which answers instantly formulas or mathematical problems that are presented, but the most curious of your case, is that it is able to see the numbers like shadows, colors and textures. In fact, the way numbers are represented in your head is very logical: to multiply two numbers you see two shadows instantly appears third shade that corresponds to the answer to the question. Mental images.
Tammet's abilities beyond the super intelligence, as they get closer to extraordinary mental qualities. - The following is a video of Daniel Tammet on The Late Show with David Letterman, is a very funny interview is in English but, excuse me-
So ... What genius lies? Scientists have been unable to answer this question, but me! Hahaha but IMHO is: The genius depends equally genetics and / or environment where the individual develops

Remixed brain waves reveal soundtrack of the human brain

Scientists have combined and translated two kinds of brain wave recordings into music, transforming one recording (EEG) to create the pitch and duration of a note, and the other (fMRI) to control the intensity of the music. The research, published November 14 in the open access journal PLOS ONE by Jing Lu and colleagues from the University of Electronic Science and Technology, China, reveals an improved method to reflect the physiological processes of the scale-free brain in music.

Previous research published in PLOS ONE by the same group has described how EEG amplitudes and waveforms may be converted to music. In the past, researchers at the Department of Homeland Security's Science and Technology Directorate have also explored the possibility of a form of neuro-training called 'Brain Music', which uses music created from an individual's brain waves to help the individual move from an anxious state to a relaxed state.

This new study uses simultaneous EEG and fMRI recordings to better represent the activity of the brain in musical notes. According to the researchers, this brain music "embodies the workings of the brain as art, providing a platform for scientists and artists to work together to better understand the links between music and the human brain."

The authors also suggest that combining EEG and fMRI data may produce music that better reflects the functional activity of the brain, potentially leading to improvements useful for clinical diagnosis or biofeedback therapy in the future.

15 Big Ways The Internet Is Changing Our Brain

15 Big Ways The Internet Is Changing Our Brain

Noted science-fiction writer Isaac Asimov predicted that one day, we'd "have computer outlets in every home, each of them hooked up to enormous libraries where anyone can ask any question and be given answers, be given reference materials, be something you're interested in knowing, from an early age, however silly it might seem to someone else," and with this appliance, be able to truly enjoy learning
instead of being forced to learn mundane facts and figures. His insight has proven to be amazingly accurate, as we now live in a world with the Internet, where nearly the entire wealth of human knowledge can live at our fingertips or even in our pockets, from being able to summon email from our smart phones to earning entire degrees from accredited online projects. We can also earn these degrees in a variety of options including associate degrees, bachelor degrees, master´s degrees, and even PHDs- all online. Such an amazing feat, of course, doesn't happen without impacting our lives, and scientists have begun to note that the Internet has not only served to fulfill our brains' curiosities, but also rewired them. So what exactly is the Internet doing to our brains? Read on to find out.
    1. The Internet is our external hard drive
    2. Children are learning differently

    3. We hardly ever give tasks our full attention

    4. We don't bother to remember

    5. We're getting better at finding information
    6. Difficult questions make us think about computers

    7. IQ is increasing over time

    8. Our concentration is suffering

    9. We're getting better at determining relevance
    10. We're becoming physically addicted to technology

    11. The more you use the Internet, the more it lights up your brain

    12. Our brains constantly seek out incoming information

    13. We've become power browsers

    14. Online thinking persists even offline

    15. Creative thinking may suffer
