Cyborg Spy Beetles are no longer a thing of the future. UC Berkeley (funded by DARPA) has created cyborg beetles guided wirelessly via laptop. These spy beetles were created with the intent of bugging actual conversations, literally acting as the "fly on the wall". [more inside]

What can we learn from quadrapeds about our own bipedal gait? Recently, a group of researchers has taught rhesus macaques how to walk, and then used neural recordings to develop a model of a functioning brain-machine interface (BMI) designed to take the signals from your brain and use them to interface with a prosthetic leg, which would allow previously paralyzed patients to literally walk again.

Functional MRI (fMRI) is a widely used technique of brain imaging in the cognitive sciences, allowing researchers to visualize what part of the brain is responding to certain stimuli, resulting in striking images of live brains. These days, fMRI is seeing more non-research use, such as forming the basis of controversial new lie detectors. Craig Bennett, a postdoctoral researcher at UCSB, submitted a whole Atlantic salmon to fMRI analysis, and found that this fish could apparently detect, and respond to, the the emotional state of human beings (poster). Remarkable science, especially considering the salmon was dead at the time. [more inside]

The Neuroscience of McGriddles: Evolutionary biology offers hypotheses about why we enjoy eating. "When you eat at McDonald's, a big part of the pleasure comes from the fact that the food is sustenance, fuel, energy. Even mediocre food is a little rewarding."

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.

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."

As the market plummets, it might be interesting to look at the neurological background in the breakdown of trust. The author, Jonah Lehrer, is a young brainiac writer for Seed and the excellent Frontal Cortex. l Scientists immediately discovered a strong neural signal that drove many of the investment decisions. The signal was fictive learning. l One way to think of the financial markets right now is that instead of being populated by rational agents, they're full of people with borderline personality disorder.

"Associative Musical Visual Intelligence (or "amvi" for short) is a type of intelligence that's difficult enough to define, let alone test. Many creative people can associate across sensory domains: they "hear" hints of shapes and can "taste" the essense of colors. At its most extreme this phenomenon is called synesthesia. However, I believe that creative people subconsciously employ elements of synesthesia every day when attempting to think of things in new ways. This is a logic test that attempts to measure one's ability to correlate musical phrases with abstract shapes and symbols." [more inside]

"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.

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).

A review of the current state of gender based brain research shows that women and men differ both in the way their brains are constructed and in how they function.

..correlation between brain region size in adults and sex steroid action in utero suggests that at least some sex differences in cognitive function do not result from cultural influences or the hormonal changes associated with puberty--they are there from birth.
Treatment for such things as schizophrenia and depression will likely have gender specific variations in the future. Previously, brain research that examined gender differences was considered controversial because it was argued that the results might give rise to more sex discrimination against women. That view may be changing.

Recent neuroscience research suggests that Democrats and Republicans are not nearly as far apart as they seem (NYT). Will an awareness that we are conning ourselves to feel alienated from each other help to close the political gap? Or, are we conned by science and the media?

Nootropics ("smart" drugs) - all wish to be smarter, correct ? And - while exercise, nutrition, learning, travel, and social interaction (the last 3 via release of neurotrophins) effectively do this, Nootropic drugs have been researched since the 1950's and have been shown to cause at least short term cognitive function enhancement. Piracetam, the first of this drugs, shows promise in the treatment of Alzheimer's and Attention deficit Disorder. Alas, as with poor little Algernon, the effect seems temporary. Nootropics can be a little difficult to acquire in the US. Beer is not a nootropic, but sex on the other hand.....
