Gender Swap - Experiment with The Machine to be Another. "Gender Swap is an experiment that uses The Machine to be Another system as a platform for embodiment experience (a neuroscience technique in which users can feel themselves like if they were in a different body). In order to create the brain illusion we use the immersive Head Mounted Display Oculus Rift, and first-person cameras. To create this perception, both users have to syncronize their movements. If one does not correspond to the movement of the other, the embodiment experience does not work. It means that both users have to constantly agree on every movement they make. Throughout this experiment, we aim to investigate issues like Gender Identity, Queer Theory, feminist technoscience, Intimacy and Mutual Respect." [NSFW, Via]
The Final Moments of Karl Brant. "In the near future, a neurologist and two homicide detectives use experimental brain taping technology to question a murder victim about his final moments." [Via]
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."
Humans, Version 3.0. "The next giant leap in human evolution may not come from new fields like genetic engineering or artificial intelligence, but rather from appreciating our ancient brains." [Via] [more inside]
Ray Kurzweil: Reverse-Engineering of Human Brain Likely by 2030. PZ Myers: Ray Kurzweil does not understand the brain.
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."
A Mind in the Water: The dolphin as our beast of burden. "The shocking double life of the dolphin, featuring neuropsychologists, hippies, spies, and extraterrestrials."
Understanding the Anxious Mind. A good article on the psychology of anxiety and how an anxious temperament at birth can ebb and flow during one's lifetime. [Via]
Torturing the brain (PDF). Extreme pain and stress can actually impair a person's ability to tell the truth. [Via]
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."

The universal grammar of birdsong is genetically encoded. "A new study, published online in the journal Nature, shows that the songs of isolated zebra finches evolve over multiple generations to resemble those of birds in natural colonies. These findings show that song learning in birds is not purely the product of nurture, but has a strong genetic basis, and suggest that bird song has a universal grammar, or an intrinsic structure which is present at birth."
David Kessler Knew That Some Foods Are Hard to Resist; Now He Knows Why. Former FDA commissioner David Kessler goes dumpster-diving to investigate the neurological impact of eating junk food. [Via]
Philosophy’s great experiment. "Philosophers used to combine conceptual reflections with practical experiment. The trendiest new branch of the discipline, known as x-phi, wants to return to those days. Some philosophers don’t like it." [Via]

That Voodoo That Scientists Do. "When findings are debated online, as with a yet to be released paper (PDF) that calls out the field of social neuroscience, who wins?"
How Google Is Making Us Smarter: Humans are "natural-born cyborgs," and the Internet is our giant "extended mind."
If I Were You: Perceptual Illusion of Body Swapping. Expanding on previous experiments, researchers discover how to induce a "body-swap" illusion, whereby subjects perceive the body of another as if it were their own.
Art as Visual Research: Art and neuroscience combine in creating fascinating examples of illusory motion.
Brain's 'Hate Circuit' Identified. "People who view pictures of someone they hate display activity in distinct areas of the brain that, together, may be thought of as a 'hate circuit', according to new research by scientists at UCL (University College London)."
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]
A New State of Mind. "New research is linking dopamine to complex social phenomena and changing neuroscience in the process."
How magicians control your mind. "Magic isn't just a bag of tricks - it's a finely-tuned technology for shaping what we see. Now researchers are extracting its lessons (PDF)." [Via BB and MH]
Mapping the Structural Core of Human Cerebral Cortex. A new study of the connections in the brain has identified the brain's central hub.
You know the feeling that something is on the tip of your tongue? It offers deep insights into the nature of the mind. [Via The Frontal Cortex]
"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.

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.

BrainPaint. Beautiful, real-time images created through neurofeedback by using the electrical activity of the brain to seed fractal patterns.
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).
The Shapes of Thought is "an exploration of the visualization of emotion as EEG and other bioelectrical signals over time as retrievable data in three-dimesnional forms." It's part of the Einstein's Brain project. [Via Neurofuture.]
