University of Washington researchers have performed what they believe is the first noninvasive human-to-human brain interface, with one researcher able to send a brain signal via the Internet to control the hand motions of a fellow researcher.

Using electrical brain recordings and a form of magnetic stimulation, Rajesh Rao sent a brain signal to Andrea Stocco on the other side of the UW campus, causing Stocco’s finger to move on a keyboard. (more…)

Scanning the Brain for Impending Error

UA computer science doctoral student Federico Cirett is using new technology to predict, in advance, when people will make a mistake. He’s been testing subjects taking the SAT exam in math.

Our bodies and brains tend to give us good cues about when we are becoming stressed, fatigued or overwhelmed.

But what if, with near exact precision, you could predict when heightened levels of fatigue were about to cause you to make a mistake?

University of Arizona doctoral student Federico Cirett believes he’s found a way – and with about 80 percent accuracy. (more…)

University of Maryland Researcher Asks – What Does Love Look Like?

COLLEGE PARK, Md. – What does love look like? A dozen roses delivered on an ordinary weekday? Breakfast in bed? Or just a knowing glance between lovers?

While outward displays of love are fairly easy to discern, a researcher in the College of Behavioral and Social Sciences is taking a decidedly “inward” approach to documenting this most complex of human emotions. (more…)

‘Buyer Beware: Advertising May Seduce Your Brain’

Are you wooed by advertising? Of course you are. After all, it’s one thing to go out and buy a new washing machine after the old one exploded, quite another to impulse-buy that 246-inch flat screen TV that just maybe, in hindsight, you didn’t really need.

Advertisers come at you in two ways. There is the just-the-facts type of ad, called “logical persuasion,” or LP (“This car gets 42 miles to the gallon”), and then there is the ad that circumvents conscious awareness, called “non-rational influence,” or NI (a pretty woman, say, draped over a car).

Crossing Your Arms Relieves Pain

Crossing your arms reduces the intensity of pain you feel when receiving a painful stimulus on the hand, according to research by scientists at UCL.

Published in the current issue of the journal PAIN, the research shows that crossing your arms over the midline (an imaginary line running vertically down the centre of the body) confuses the brain and reduces the intensity of the pain sensation. (more…)

Scientists to Spy on People’s Dreams and Thoughts

Until now it was believed that a person is unable to read the thoughts of fellow human beings. “Spying” on the dreams of another person appeared unrealistic. However, recent research by American scientists revealed that both these things are quite possible. Overly complex devices and paranormal abilities are not required to do so.

Recently, a respectable scientific journal Nature published an article that ten years ago would have been considered a fiction and would not have been publication at all. A group of American researchers led by Dr. Moran Cerf claims to have found a way to electronically records and decipher human dreams and thoughts. No complicated devices are required. The entire transcript can successfully go through an electroencephalograph – a device that for decades has been used by neuroscientists around the world. (more…)
