Genes that cause depression?

A gene variant associated with serotonin transport (STG) , and normally associated with depression is strangely more prevalent, but also less likely to induce depression in collectivistic East Asian cultures. The study took data from 29 countries, and found a consistent trend towards this same genetic variant being strongly associated with episodes of major depression in Western cultures.

Big Brother's just a beetle on the wall

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]

Monkeys inform humans about walking

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.

A Few Strange Notes About Schizophrenia

Here's a strange one for the books: Science has taken notice that a really, really LARGE proportion of schizophrenic patients smoke. In fact, Scientific American Mind reports that an average of 85% of schizophrenic patients smoke cigarettes compared to only 20% in the general population. Many schizophrenics also appear to have abnormal thermoregulation, an impaired ability to understand body language, an inability to perceive an optical illusion called "the hollow mask illusion," an impaired ability to produce a brain protein known as the muscarinic M1 receptor, and an abnormally large number of genetic mutations known as CNV's or "copy number variations."

The Wisdom of Salmon

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]

Marching through the claims like Sherman through Georgia

Neuroscientist Lise Eliot finds that claims of sex differences fall apart. In one study, scientists dressed newborns in gender-neutral clothes and misled adults about their sex. The adults described the "boys" (actually girls) as angry or distressed more often than did adults who thought they were observing girls, and described the "girls" (actually boys) as happy and socially engaged more than adults who knew the babies were boys. Dozens of such disguised-gender experiments have shown that adults perceive baby boys and girls differently, seeing identical behavior through a gender-tinted lens. [more inside]

Is there no problem the internet can't solve - Flickr finds only known photo of Phineas Gage

While many quirky news buffs may be aware of the story of Phineas Gage -- the Vermont railroad foreman who had a three foot iron rod penetrate his skull as the result of an explosion and lived to tell about it -- fewer know that the only known photograph of him was recently discovered. Fewer still know that the identification of that photograph happened via a Flickr comment. (no thanks to you LA Times, previously) [more inside]

Calories are delicious

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

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."

I await Trepanation with great Trepidation.

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.

test your your brain

Test My Brain was set up by Harvard's Vision Lab and Social Neuroscience and Psychopathology Lab. There are five tests online at the time of this post; take one and maybe you'll learn something about yourself that you may not have known (other than your special ability to slack off on MetaFilter when you should be working). At the same time, you'll be helping researchers collect data from a wide range of subjects. One of the collaborators, Professor Ken Nakayama, is also responsible for creating these online tests for faceblindness. [previously] [more inside]

The Neurobiology of Birdsong

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."

"Genius is nothing more nor less than childhood recovered at will."

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."

Reports of the Demise of Materialism Are Premature

"You cannot overestimate how threatened the scientific establishment is by the fact that it now looks like the materialist paradigm is genuinely breaking down.", argues psychiatrist Jeffrey Schwartz, part of a growing "non-material neuroscience" movement, an approach that evokes Cartesian dualism - the belief that the mind is not linked to the body, taking on the qualities of a soul. However growing the movement might be, others argue that the end of materialism is far from nigh. (via)

neurobiology of trust

As the market plummets, it might be interesting to look at the neurological background in the breakdown of trust.

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.
