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.

Your brain has at least four different senses of location — and perhaps as many as 10 — and each is different, according to new research from the Kavli Institute for Systems Neuroscience at the Norwegian University of Science and Technology. The brain has a number of “modules” dedicated to self-location, they found. Each module contains its own internal GPS-like mapping system that keeps track of movement, and has other characteristics that also distinguish one motion from another. “We have at least four senses of location,” says Edvard Moser, director of the Kavli Institute. “Each has its own scale for representing the external environment, ranging from very fine to very coarse. “The different modules react differently to changes in the environment. Some may scale the brain’s inner map to the surroundings, others do not. And they operate independently of each other in several ways.” This is also the first time that researchers have been able to show that a part of the brain that does not directly respond to sensory input, called the association cortex, is organized into modules. The research was conducted using rats. (via The many maps of the brain | KurzweilAI)
Roberto Osti’s fantastical anatomical drawings explore intersections between modern science and myth. Interested in how humans might one day reach immortality through cloning or the potential reality of hybrid monsters, Osti’s awe-inspiring images merge the visual language of scientific drawing with subjects that reveal the absurd potential of rational science.
