After emerging from drug-induced hallucinations, people often describe their experiences as mystical and introspectively illuminating. But psychedelic mushrooms, peyote, LSD and related drugs can also cause confusion, paranoia and emotional angst — raising questions about whether they have any long-term impact on mental health.

A new study of long-time adult soccer players has found changes in the brain similar to traumatic brain injury as a result of repeated “headers” of the ball. The study also found an association between players who had repeatedly headed, and slight memory loss. Read more
A computer can predict what you’re dreaming about based on brain wave activity, new research suggests. By measuring people’s brain activity during waking moments, researchers were able to pick out the signatures of specific dream imagery — such as keys or a bed — while the dreamer was asleep.

Mission to Mars Could Mess With Your Brain: The high-energy particles that buzz around outside of our protective magnetosphere aren’t only a trigger for nasty cancers, they may also trigger certain brain defects, such as Alzheimer’s disease.
Just add it to the list of “reasons why humans don’t belong in space” — a list that will never stifle our urge to explore other worlds.
Childhood Hunger a Boost for Elderly Brains?Older people who remembered going hungry as children were slower to lose their mental sharpness as they reached old age.
Interesting to think that the experiences we have as a child can influence our brains decades later into old age…
During a trance-like session of psychography, experienced mediums in Brazil allow themselves to become receptive to spirits or dead souls. Then they write automatically, channeling the voices of those they believe to be speaking to them […] “I don’t think this does anything to make (the experience) less real or less profound or to make it less important in the moment,” said Andrew Newberg, a neuroscientist at Thomas Jefferson University in Philadelphia.
A CT scanner uses radiation to produce a three-dimensional image of the insides of the human body. X-rays are fired through the body, and scanners pick up the path of the rays, leading to a detailed image of the body. It can be used to detect and diagnose epilepsy, Alzheimer’s disease, cancers, heart disease and medical issue.
If robots can think like us, would they deserve rights? At what point would we need to start thinking about artificially intelligent robots less as things and more as something else…
Maybe that’s too deep for this time of day. Happy Hour anyone?
Will this summer be remembered as a turning point in the story of man versus machine? On June 23, with little fanfare, a computer program came within a hair’s breadth of passing the Turing test, a kind of parlour game for evaluating machine intelligence devised by mathematician Alan Turing more than 60 years ago.
Turing proposed the test – he called it “the imitation game” – in a 1950 paper titled “Computing machinery and intelligence”. Back then, computers were very simple machines, and the field known as Artificial Intelligence (AI) was in its infancy. But already scientists and philosophers were wondering where the new technology would lead. In particular, could a machine “think”?
This is some scary stuff.
Don’t think of your password! D’oh!
A team of researchers from the University of Oxford in Geneva and the University of California in Berkeley just showed how easy it is to hack a human brain and pluck things such as bank details from your head. They did so using an off-the-shelf Emotiv brain-computer interface that only cost a few hundred dollars.
Their experiments made it easier to calculate their address or bank account numbers.
Sad Keanu thinks this reminds him of something.
