“The mother has first dibs on influencing the child’s brain,” said Patricia Kuhl, of the Institute for Learning & Brain Sciences at the University of Washington, in a press release. “The vowel sounds in her speech are the loudest units and the fetus locks onto them.” Previous studies have shown that the perception of speech sounds develops in infants long before they are able to speak themselves. Between the ages of 6 months and a year, for example, babies quickly get better at telling the difference between sounds often used in their native languages. At the same time, they rapidly lose the ability to distinguish between the typical sounds of other languages. (via Language Learning Begins in Womb : Discovery News)

Can We Have Brain-to-Brain Communication?
Michio Kaku says this brain-to-brain communication would involve not just the exchange of information, but also the transmission of emotions and feelings, “because these are also part of the fabric of our thoughts.”
IQ tests are misleading because they do not accurately reflect intelligence, according to a study which found that a minimum of three different exams are needed to measure someone’s brainpower.
For more than a century our intelligence quotient (IQ) has been used to measure how clever people are and Mensa, the society for the intellectual elite, has even used the test to weed out sub-par applicants. But now the scale has been dismissed as a “myth” by scientists who found that our intelligence can only be predicted by combining results from at least three tests of our mental agility. Different circuits within the brain are used for different thought processes, the researchers showed, meaning separate tests of short-term memory, reasoning and verbal skills are needed to measure someone’s overall intelligence. Their landmark study was based on the results of an online intelligence test which was launched by the Daily Telegraph and New Scientist two years ago, and attracted more than 110,000 responses. Dr Roger Highfield, the Telegraph columnist and one of the authors of the paper, said: “When you come to the most complex known object, the human brain, the idea that there is only one measure of intelligence had to be wrong.

I am, as I say, addicted, and I keep a sharp eye out for trends. Over the last several years, I’ve noticed a striking increase in articles whose common theme is where things happen in the brain. It appears that recent technological developments in ‘neural imaging’ have made it possible to measure the amount of activity that’s going on in a given brain region while a subject is engaged in some experimental task. And, though perhaps not mandatory, it’s natural enough to infer from a reliable correlation between a mental process and a locus of neural activity that the latter is the site of the former. If there’s a place in the brain where you find a whole lot of neurons going off when and only when whoever owns the brain is thinking about teapots, it’s at least plausible, all else being equal, that you’ve found where in that brain its thinking about teapots happens. Likewise, if certain neurons fire at certain frequencies just when a guy is conscious, one might infer that that’s where his consciousness hangs out. All the more so if the correlation holds across subjects.
