New research from the University of Southampton has demonstrated that it is possible for communication from person to person through the power of thought — with the help of electrodes, a computer and Internet connection.
Brain-Computer Interfacing (BCI) can be used for capturing brain signals and translating them into commands that allow humans to control (just by thinking) devices such as computers, robots, rehabilitation technology and virtual reality environments.
This experiment goes a step further and was conducted by Dr Christopher James from the University’s Institute of Sound and Vibration Research. The aim was to expand the current limits of this technology and show that brain-to-brain (B2B) communication is possible.

In the 18 months since the “missing link of electronics” was discovered in Hewlett-Packard’s laboratories in Silicon Valley, California, memristors have spawned a hot new area of physics and raised hope of electronics becoming more like brains. […]
Memristors behave a bit like resistors, which simply resist the flow of electric current. But rather than only respond to present conditions, a memristor can also “remember” the last current it experienced.
That’s an ability that would usually require many different components. “Each memristor can take the place of 7 to 12 transistors,” says Stan Williams, head of HP’s memristor research. What’s more, it can hold its memory without power. By contrast, “transistors require power at all times and so there is a significant power loss through leakage currents”, Williams explains. […]
The similarities between memristive circuits and the behaviour of some simple organisms suggests the hybrid devices could also open the way for “neuromorphic” computing, says Williams, in which computers learn for themselves, like animals.

Sitting up straight in your chair isn’t just good for your posture – it also gives you more confidence in your own thoughts, according to a new study.
Researchers found that people who were told to sit up straight were more likely to believe thoughts they wrote down while in that posture concerning whether they were qualified for a job.
On the other hand, those who were slumped over their desks were less likely to accept these written-down feelings about their own qualifications.
The results show how our body posture can affect not only what others think about us, but also how we think about ourselves, said Richard Petty, co-author of the study and professor of psychology at Ohio State University.

8 Circuit Brain: Navigational Strategies for the Energetic Body
Nearly 40 years after widespread fear over recreational abuse of LSD and other hallucinogens forced dozens of scientists to abandon their work, researchers at a handful of major institutions – including UCSF and Harvard University – are reigniting studies. Scientists started looking at less controversial drugs, like ecstasy and magic mushrooms, in the late 1990s, but LSD studies only began about a year ago and are still rare.
The study at UCSF, which is being run by a UC Berkeley graduate student, is looking into the mechanisms of LSD and how it works in the brain. The hope is that such research might support further studies into medical applications of LSD – for chronic headaches, for example – or psychiatric uses. […]
In 1966, the federal government made LSD illegal, and by the early 1970s, research into all psychedelic drugs in humans had come to a halt, although some scientists continued to study the drugs in animals.
Depression seems to pose an evolutionary paradox. Research in the US and other countries estimates that between 30 to 50 percent of people have met current psychiatric diagnostic criteria for major depressive disorder sometime in their lives. But the brain plays crucial roles in promoting survival and reproduction, so the pressures of evolution should have left our brains resistant to such high rates of malfunction. Mental disorders should generally be rare — why isn’t depression? […]
In an article recently published in Psychological Review, we argue that depression is in fact an adaptation, a state of mind which brings real costs, but also brings real benefits. […]
So what could be so useful about depression? Depressed people often think intensely about their problems. These thoughts are called ruminations; they are persistent and depressed people have difficulty thinking about anything else. Numerous studies have also shown that this thinking style is often highly analytical. They dwell on a complex problem, breaking it down into smaller components, which are considered one at a time.
This analytical style of thought, of course, can be very productive. Each component is not as difficult, so the problem becomes more tractable. Indeed, when you are faced with a difficult problem, such as a math problem, feeling depressed is often a useful response that may help you analyze and solve it. For instance, in some of our research, we have found evidence that people who get more depressed while they are working on complex problems in an intelligence test tend to score higher on the test. […]
Depression is nature’s way of telling you that you’ve got complex social problems that the mind is intent on solving. Therapies should try to encourage depressive rumination rather than try to stop it, and they should focus on trying to help people solve the problems that trigger their bouts of depression. (There are several effective therapies that focus on just this.) It is also essential, in instances where there is resistance to discussing ruminations, that the therapist try to identify and dismantle those barriers.
For those who think modernity or civilization or technology is the problem:
Or, perhaps, depression might be like obesity — a problem that arises because modern conditions are so different from those in which we evolved. Homo sapiens did not evolve with cookies and soda at the fingertips. Yet this is not a satisfactory explanation either. The symptoms of depression have been found in every culture which has been carefully examined, including small-scale societies, such as the Ache of Paraguay and the !Kung of southern Africa — societies where people are thought to live in environments similar to those that prevailed in our evolutionary past.

People believe what they see, and they’re willing to punish each other for it — apparently even when what they’re seeing is a fake video that doesn’t jibe with real-life experience.
Psychologists have long known that our memories of past events can be influenced by misleading information, but now they’ve proven that doctored video evidence can convince people to offer false eyewitness testimony. In a study of 60 college students performing a computerized gambling task, nearly half were willing to testify that they saw their partner cheat in real life after watching fabricated video evidence. Of students who were told that video evidence existed but didn’t watch the footage themselves, only 10 percent gave false testimony. […]
In the study, each student was paired with a member of the research team disguised as another participant. The pair sat side-by-side and played a computerized gambling game, which involved betting fake money based on the likelihood of answering a multiple choice question correctly. Each person was in charge of keeping track of their own wins; when a subject correctly answered a question, they got to take money from a shared “bank,” and when they incorrectly answered a question, they had to put money back. Participants were told that at the end of the game, the person who made the most money would win a prize.
After the gambling concluded, the researchers used Final Cut Pro to alter a video recording of the game and make it look like the partner had cheated. Five to seven hours after the first task, students were called back to the lab and told that their absent partner was suspected of cheating. One-third of the students were also told that the researchers had video evidence of the cheating, and another one-third got to watch the doctored video themselves.
Before asking participants to sign an eyewitness testimony, the researchers emphasized that no one should testify unless they were 100 percent sure they had seen their partner cheat, and they emphasized that the cheater would be punished. Students who watched the fake video were far more likely to give false testimony than students who heard about the video or were simply told that their partner was suspected of cheating.

New Scientist has a fascinating article on the way the color red effects our minds. Definitely worth reading in full.
IMAGINE you are an experienced martial arts referee. You are asked to score a number of taekwondo bouts, shown to you on video. In each bout, one combatant is wearing red, the other blue. Would clothing colour make any difference to your impartial, expert judgement? Of course it wouldn’t.
Yet research shows it almost certainly would. 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.”
This is just the latest piece of research suggesting that exposure to certain colours can have a significant effect on how people think and act. Up to now most of the research has focused on red clothing in sport, but other colours and settings are being investigated too. It is becoming clear that colours can have an important, unappreciated effect on the way your mind works – one that you really ought to know about.

The research shows men who spend even a few minutes in the company of an attractive woman perform less well in tests designed to measure brain function than those who chat to someone they do not find attractive.
Researchers who carried out the study, published in the Journal of Experimental and Social Psychology, think the reason may be that men use up so much of their brain function or ‘cognitive resources’ trying to impress beautiful women, they have little left for other tasks.
The findings have implications for the performance of men who flirt with women in the workplace, or even exam results in mixed-sex schools.
Women, however, were not affected by chatting to a handsome man.
Mind Hacks shares this excerpt from Hallucinations and Their Impact on Art:
What is more curious to the contemporary man is that the medieval description of insanity does not include hallucinations; and the experience of possession (passivity phenomena) is not described as occurring concurrently with or as part of a visionary state.
In Western Europe from AD 500-1500, people who heard voices or saw visions considered themselves, and were considered buy their contemporaries, to have had an actual perceptual experience of either divine or satanic inspiration. They were not considered mad and were not treated as such. Hallucinations (fantasmata) were only considered mad when combined with trickery (prestigiae).
