Brain wiring a no-brainer? Scans reveal astonishingly simple 3D grid structure
"Far from being just a tangle of wires, the brain's connections turn out to be more like ribbon cables -- folding 2D sheets of parallel neuronal fibers that cross paths at right angles, like the warp and weft of a fabric,"

BBC News - Vegetative state patients can respond to questions
"Scientists have been able to reach into the mind of a brain-damaged man and communicate with his thoughts."

The research, carried out in the UK and Belgium, involved a new brain scanning method.

Awareness was detected in three other patients previously diagnosed as being in a vegetative state.

Alcohol substitute that avoids drunkenness and hangovers in development - Telegraph
"The synthetic alcohol, being developed from chemicals related to Valium, works like alcohol on nerves in the brain that provide a feeling of wellbeing and relaxation.

But unlike alcohol its does not affect other parts of the brain that control mood swings and lead to addiction. It is also much easier to flush out of the body.

Finally because it is much more focused in its effects, it can also be switched off with an antidote, leaving the drinker immediately sober. "

Scientists develop nasal spray that improves memory
"If a nasal spray can improve memory, perhaps we're on our way to giving some folks a whiff of common sense, such as accepting the realities of evolution," said Gerald Weissmann, M.D., Editor-in-Chief of The FASEB Journal. "This is exciting piece of interdisciplinary science, since IL-6 had previously been considered a by-product of inflammation, not an agent that affects cognition."

Winners wear red: How colour twists your mind - New Scientist
"Last year, sports psychologists at the University of Münster, Germany, showed video clips of bouts to 42 experienced referees. They then played the same clips again, digitally manipulated so that the clothing colours were swapped round. The result? In close matches, the scoring swapped round too, with red competitors awarded an average of 13 per cent more points than when they were dressed in blue (Psychological Science, vol 19, p 769). "If one competitor is strong and the other weak, it won't change the outcome of the fight," says Norbert Hagemann, who led the study. "But the closer the levels, the easier it is for the colour to tip the scale.""

The powerful and mysterious brain circuitry that makes us love Google, Twitter, and texting. - By Emily Yoffe - Slate Magazine
"It is the liking system that Berridge believes is the brain's reward center. When we experience pleasure, it is our own opioid system, rather than our dopamine system, that is being stimulated. This is why the opiate drugs induce a kind of blissful stupor so different from the animating effect of cocaine and amphetamines. Wanting and liking are complementary. The former catalyzes us to action; the latter brings us to a satisfied pause. Seeking needs to be turned off, if even for a little while, so that the system does not run in an endless loop."

How to hallucinate with ping-pong balls and a radio
"Much of what we think of as being out there actually comes from in here, and is a byproduct of how the brain processes sensation. In recent years scientists have come up with a number of simple tricks that expose the artifice of our senses, so that we end up perceiving what we know isn't real - tweaking the cortex to produce something uncannily like hallucinations. Perhaps we hear the voice of someone who is no longer alive, or feel as if our nose is suddenly 3 feet long."

Brain Surgery Helps a Mute Man Speak
"A surgical procedure performed by a team from Boston University, Massachusetts led by Professor Frank Guenther, has enabled a mute man to speak again. An electrode implanted in the patient’s brain made it possible for the patient to produce vowels by thinking them, using a speech synthesizer. In the future, this breakthrough may help patients with similar injuries produce entire sentences, using signals from their brains."

New map IDs the core of the human brain (7/2/2008)
"An international team of researchers has created the first complete high-resolution map of how millions of neural fibers in the human cerebral cortex -- the outer layer of the brain responsible for higher level thinking -- connect and communicate."

Mind Hacks: Natalie Portman, cognitive neuroscientist
"Natalie Portman is best known for her roles in Hollywood movies like Star Wars, Cold Mountain and V for Vendetta. What is less known is that she was co-author of a scientific paper on the neuroscience of child development. This is about her research."
