A Case Against Eating Disorder Not Otherwise Specified (EDNOS)

by Tetyana in Science of Eating Disorders

This study is a follow up on the previous study (last entry) which examined the problems with the EDNOS classification, the frequency of transitions between eating disorders and how the DSM should be changed to reflect the clinical reality of eating disorders (and what is the clinical reality?.

In this 2010 Eddy et al paper, the authors followed 246 women who were initially diagnosed with either AN or BN, for an average of 9 years. The main goal was to study the growing disparity between (1)........ Read more »

Connectomics in the retina

by Patrick Mineault in xcorr

Connectomics and some of its promises made news last week when Sebastian Seung and Tony Movshon went head to head in a debate broadcast by Radiolab (archived here). I didn’t watch the webcast, but I wanted to point out a quite fascinating recent study by Briggman, Helmstaedter and Denk (2011) that shows some of the [...]... Read more »

Juries not being swayed

by Janet Kwasniak in Thoughts on thoughts

On Neuroethics and Law Blog (here) there was reference to a paper giving evidence that scan images do not have the effect on juries that has been reported. Let us hope this is true – scans are far too new and difficult to understand in context, to be used in court if they wield [...]... Read more »

Competitive versus cooperative #exergame play on Cognitive Function

by Stephen P. Yang, Ph.D. in ExerGame Lab

For at-risk ethnic minority adolescents, exergaming helped them lose weight (over 10 weeks) and improved executive function skills when compared to a control group. Although there have been many studies in exergaming, most of it has centered around physiological outcomes, but this is one of only a handful of studies that measured cognitive function over a period of time. This study is from Amanda's 2010 dissertation from Georgetown.

Real or Not Real: NeuroTorture

by TheCellularScale in The Cellular Scale

I am not going to lie, I recently got caught up in Hunger Games fever, tearing through all three books at a breakneck pace and staying up way too late doing so. While these books raise interesting questions on some of my favorite topics (like 'how much is too much to sacrifice for victory?'), one particular neuroethics issue jumped out and stung me.Without divulging any plot points or spoilers, I will explain:In the last book, Mockingjay, a good guy is taken hostage by the bad guys.&nb........

Clothes make the man—literally

by Jordan Gaines in Gaines, on Brains

A study by Hajo Adam and Adam Galinsky of Norwestern University observed an interesting phenomenon: wear a white coat you believe belongs to a doctor, and you'll be more focused. Wear a white coat you believe belongs to a painter, and you won't see that improvement. In other words, clothes may literally make the man (or woman).... Read more »

The Instability of Eating Disorder Diagnoses

by Tetyana in Science of Eating Disorders

Eating disorders are rarely static. Symptoms fluctuate, waxing and waning as circumstances change. Often, these fluctuations lead to diagnostic crossover – between subtypes of one disorder or to a different eating disorder altogether. The heterogeneity of symptom severity and frequency led to the establishment of the “eating disorder not otherwise specified” diagnosis in the Diagnostic and Statistical Manual. Essentially, it is everything that doesn’t quite fit into the “anorexia nervo........ Read more »

Brainbrawl round-up

by Zen Faulkes in NeuroDojo

Columbia University hosted a debate between Tony Movshon and Sebastian Seung last Monday, “Does the brain’s wiring make us who we are?” This became known informally as “brainbrawl.” I watched it livestreamed through the Radiolab site, and someone had the wherewithal to grab the video below (which Radiolab said they weren’t planning on archiving). Radiolab did archive the live chat here.

Where’s the fight?

As I predicted, it was a much more sedate affair than the “brainbrawl........ Read more »

Neurostimulation - The Genius Machine?

by Neuroskeptic in Neuroskeptic

Do you wish you were smarter? Are you often baffled by puzzles?According to Australian neuroscientists Chi and Snyder, all you need is a bit of electric assistance: Brain stimulation enables the solution of an inherently difficult problem.In their study, 22 volunteers were faced with the 9 dots problem, a notoriously difficult puzzle. The goal here is to draw exactly four straight lines connecting all nine of these dots, without retracing any line, or lifting your pen from the page.Can you ........ Read more »

Topography conquers all

by Patrick Mineault in xcorr

The eye faithfully maps visual space to different positions on the retina. This retinotopy is preserved as the signal is forwarded from retinal ganglion cells to the LGN, then to V1, and onwards. Cells which are physically adjacent on a retinotopic map have receptive fields corresponding to similar positions in space. More generally, properties like [...]... Read more »

Paper trail day trip: Genomic systems neuroscience

by Michael Patterson in ...And You Will Know Me By The Trail of Papers

Theoretically, each animal's taste repertoire is determined by the food it eats. For herbivores, the important tastes are sweet and bitter, which lets animals distinguish between calories and poison. For carnivores, they are umami and sour, which help identify whether meat is fresh. Flies, for whatever reason, detect carbonation in water. As omnivores, humans combine the taste repertoires of ...

Have you been keeping up with the ‘sexsomniac’ defense?

It’s been used successfully several times since we first wrote about it back in December of 2009. In 2009, we told you about a landscaper named Jan Luedecke who got drunk at a party in 2003 and fell asleep. He woke up and then went to a woman asleep on another couch, put on a [...]

Are melatonin-laced drinks just taking the piss?

by Andrew Watt in A Hippo on Campus

At the end of a long day at work there's nothing quite like the salve of a glass of red to ease the troubles from your mind. Or perhaps a scotch is more your thing (neat or on the rocks I'm not here to judge). Then again maybe yours is a gin and tonic, an old fashioned or even just a cup of chamomile. The point is whatever your poison there are few among us who don't turn to a little liquid helper as the day draws to a close. Whether to dull those frayed nerves, to placate our wor........

Brain Glue: Synapses on and around Glia

by TheCellularScale in The Cellular Scale

Astrocytes, a form of glial cell (source)Glial cells are non-neurons that populate the nervous system.  The name 'glia' comes from the Greek word for glue, and these cells were originally thought to be 'filler' cells or brain glue (not this kind). In a sense these cells are 'filler'.  When the brain is damaged, it is glia not new neurons which grow into the void.  (This can sometimes turn cancerous and lead to glioma)A recent review paper poetically summarizes the traditional........

The Genetics of Anorexia Nervosa

by Tetyana in Science of Eating Disorders

Is it the culture of thinness, obsession with dieting or just bad mothering? When it comes to determining the causes of anorexia nervosa, the answer appears to be none of the above. Increasingly, the evidence is pointing to genetics playing an important role in predisposing individuals to anorexia nervosa. Among clinicians and researchers, the notion that genetic factors are important in the development of anorexia nervosa seems uncontested. In this short review, Dr. Cynthia Bulik and colleagues........ Read more »

Next Generation Artificial Intelligence

by Jason Carr in Wired Cosmos

As computer scientists this year celebrate the 100th anniversary of the birth of the mathematical genius Alan Turing, who set out the basis for digital computing in the 1930s to anticipate the electronic age, they still quest after a machine as adaptable and intelligent as the human brain. Now, computer scientist Hava Siegelmann of the [...]... Read more »
