DIY Brain Stimulation

Inside the Strange New World of DIY Brain Stimulation. "Inspired by scientific studies, ordinary people are buying and building devices to send electrical current into their brains. Some say it has improved their memory and focus. Others have found relief from depression and chronic pain. But are they getting ahead of the science?" [Via]

The Walk Again Project

Body suit may soon enable the paralyzed to walk. "In a busy lab at Duke University, Dr. Miguel Nicolelis is merging brain science with engineering in a bid to create something fantastical: a full-body prosthetic device that would allow those immobilized by injury to walk again. On Wednesday, Nicolelis and an international group of collaborators declared that they had cleared a key hurdle on the path toward that goal, demonstrating they could bypass the body's complex network of nerve endings and supply the sensation of touch directly to the brains of monkeys."

Concealed Neuroanatomy in Michelangelo's Separation of Light From Darkness

In a Michelangelo Fresco, Visions of a Brain Stem. "It has been hiding in plain sight for the past 500 years, and now two Johns Hopkins professors believe they have found it: one of Michelangelo’s rare anatomical drawings in a panel high on the ceiling of the Sistine Chapel. Michelangelo was a conscientious student of human anatomy and enthusiastically dissected corpses throughout his life, but few of his anatomical drawings survive. This one, a depiction of the human brain and brain stem, appears to be drawn on the neck of God, but not all art historians can see it there."

Neurosecurity

Neurosecurity: security and privacy for neural devices. "An increasing number of neural implantable devices will become available in the near future due to advances in neural engineering. This discipline holds the potential to improve many patients' lives dramatically by offering improved—and in some cases entirely new—forms of rehabilitation for conditions ranging from missing limbs to degenerative cognitive diseases. The use of standard engineering practices, medical trials, and neuroethical evaluations during the design process can create systems that are safe and that follow ethical guidelines; unfortunately, none of these disciplines currently ensure that neural devices are robust against adversarial entities trying to exploit these devices to alter, block, or eavesdrop on neural signals. The authors define 'neurosecurity'—a version of computer science security principles and methods applied to neural engineering—and discuss why neurosecurity should be a critical consideration in the design of future neural devices."

Long-term effects of ecstacy

Ecstasy's long-term effects revealed. "Enough time has finally elapsed to start asking if ecstasy damages health in the long term. According to the biggest review ever undertaken, it causes slight memory difficulties and mild depression, but these rarely translate into problems in the real world. While smaller studies show that some individuals have bigger problems, including weakened immunity and larger memory deficits, so far, for most people, ecstasy seems to be nowhere near as harmful over time as you may have been led to believe."

I Contain Multitudes

First Person Plural. "An evolving approach to the science of pleasure suggests that each of us contains multiple selves—all with different desires, and all fighting for control. If this is right, the pursuit of happiness becomes even trickier. Can one self bind another self if the two want different things? Are you always better off when a Good Self wins? And should outsiders, such as employers and policy makers, get into the fray?" [Via]

Locked-In Syndrome

The Unspeakable Odyssey of the Motionless Boy. "How much of our humanity are we prepared to cede to machines? This is a dilemma of the future, but it's not much of a concern for Erik Ramsey. Erik can't move. He can't blink his eyes. And he hasn't said a word since 1999. But now, thanks to an electrode that was surgically implanted in his brain and linked to a computer, his nine-year silence is about to end." [Via]

MettaFilter

"Attention regulation and monitoring in meditation" (PDF). A recent article in Trends in Cognitive Sciences on the neuroscience of meditation, focusing on how meditation alters and sharpens the brain's attention systems. The research is being done at the Waisman Laboratory for Brain Imaging and Behavior (previously), who have also recently published research on the "Regulation of the neural circuitry of emotion by compassion meditation" (PDF), which describes how meditation can cultivate compassion by physically affecting brain regions that play a role in empathy. They shared this research with the Dalai Lama at the recent Seeds of Compassion forum.

Crockusology

How big is your crockus? In cutting edge neuroscience news, a new part of the brain has recently been identifed by the enigmatic Dr. Crockus. Described as "the detailed section of the brain, a part of the frontal lope," the crockus is apparently four times larger in females than in males, which is why girls see the details of experiences while boys see the whole but not the details.

Video Ergo Sum

Virtual Out-of-Body Experience. Using two procedures to deliberately scramble a person's visual and tactile senses, neuroscientists are able to induce "out-of-body" experiences in people. The effect is the same as the 'rubber hand illusion', but extends the effect to the whole body instead of just one limb (you can try the hand illusion for yourself).

Simian Cybernetics

Brain implants 'read' monkey minds. (No, not that monkey mind.) A group of CalTech neuroscientists have been able to predict the actions of monkeys by observing neural activity in the parietal and premotor cortices related to planning and motivation (PDF.) Other research previously allowed monkeys to control a robotic arm with their minds; this observed the higher-level goal and value signals, and could lead to more natural thought-activated prosthetic devices for people with paralysis.

Making the Mind

Making the Mind. "The general outlines of how genes build the brain are finally becoming clear, and we are also starting to see how, in forming the brain, genes make room for the environment’s essential role. While vast amounts of work remain to be done, it is becoming equally clear that understanding the coordination of nature and nurture will require letting go of some long-held beliefs."
