The simulated brain - "The scientists behind Blue Brain hope to have a virtual human brain functioning in ten years... Dr. Markram began by collecting detailed information about the rat's NCC, down to the level of genes, proteins, molecules and the electrical signals that connect one neuron to another. These complex relationships were then turned into millions of equations, written in software. He then recorded real-world data -- the strength and path of each electrical signal -- directly from rat brains to test the accuracy of the software." Is it possible to digitally simulate a brain accurately? Can it only be analog? And are there quantum effects to be considered? (previously 1 2 3 4) [more inside]

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."

We've discussed trepanation, the boring of holes in the head as practiced in antiquity and by a fringe do it yourself-ers, before. There now seems to be research indicating that the procedure may have medical merit, and even help stave off age related cognitive decline. This curious research brought to you by the Beckly Foundation which "promotes the investigation of consciousness and its modulation
from a multidisciplinary perspective" and has a sweet logo.

Why do we get "tip of the tongue" moments?? We’ve all experienced the tip of the tongue moment where we wanted to say something but just couldn’t remember the word. But what causes this momentary lapses in vocabulary?

There are times when having a fully developed brain can almost seem like an impediment. Are babies more aware of the world around them than adults are? Can "thinking like a baby" lead us to be more in tune with our creativity and our ability to learn? Scientists have taken a new look inside the baby mind, which is "unfocused, random, and extremely good at what it does."

Microscope Imaging Station opens a door to the wonder of the microscopic world and allows the layman to explore it. They seek to recreate some of the excitement and wonder that the earliest biological researchers found. Features include cells with potential as well as bad oogy. The microscopic Galleries are inhabited by zygotes and organelles.

The Brain Unveiled: A new imaging method offers a spectacular view of neural structures. Diffusion spectrum imaging, developed by neuroscientist Van Wedeen at Massachusetts General Hospital, analyzes magnetic resonance imaging (MRI) data in new ways, letting scientists map the nerve fibers that carry information between cells.

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]

"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.

Jonah Lehrer is becoming one of the most interesting science writers around. The 26-year-old Rhodes scholar and former Le Bernardin cook just published his first book, Proust Was a Neuroscientist [first chapter excerpt - NYT], an investigation of the ways poets, novelists, and artists accurately modeled the brain and memory before science did. This week he hilariously reenacted Escoffier's distillation of umami-rich veal stock [hit the audio link] with NPR's Robert Krulwich of Radio Lab. He also just published a very insightful profile of Oliver Sacks in SEED (addressing the pioneering neurologist's own recent struggles with an eye ailment) and writes a wide-ranging science blog. A new writer to watch.

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).

Researchers have found that prolonged concentration on a difficult task actually switches off a person's self awareness. Fancy experiencing this sensation for yourself? That would be an oxymoron in existence. Just lay back and let the orgasm take hold.

The first Transhuman Conference On the Law of Transhuman Persons: Whether or not you believe humans are set to evolve into gods, or AI is destined to achieve self-awareness the idea of the Transhuman is a thought provoking concept. Philosophers have debated the nature of the self, of the human for millennia. Is it time to start drafting new laws to govern all possible sentient beings on this planet? or is it all just a science of fiction? a comfortable humanist illusion?
