The where, when, how and why

by Janet Kwasniak in Thoughts on thoughts

A recent review article by Friedemann Pulvermuller looks at what is known about the neurobiology of language. He uses the question of what recent progress has been in the where, when, how and why of language processing in the brain. He does a masterful job and yet I am, personally, disappointed. In what way I [...]... Read more »

Brain Tutor HD iPad App Review

by William Yates, M.D. in Brain Posts

I have previously posted a review of the brain imaging applications Brain Tutor and 3D Brain.  My original review of the two applications for the iPhone and iPod Touch is located here and a review of the applications for the iPad are located here.The original iPad review noted that the iPad versions of both applications were essentially the iPhone version with the common 2x modification that essential doubles the size of the image to accommodate the larger screen with the iPad.  There ........

Fitter Kids = Bigger Brains

by agoldstein in WiSci

Parents take note: if you want your kids to grow bigger brains, think twice about letting schools cut recess or skimp on physical education.

Animal and human studies have long shown that exercise increases neurogenesis, especially in memory- and learning-related areas of the brain. More recently, research on human adolescents has not only confirmed these findings, but highlighted the importance of physical activity for children.... Read more »

The Brain Insula: Function and Disease

by William Yates, M.D. in Brain Posts

Nature Reviews Neuroscience is a scientific journal dedicated to neuroscience topics that recently celebrated it’s ten year anniversary.  To commemorate the accomplishment, the most highly cited articles from each of the last 10 years was identified.  This method provides a good proxy for the most important publication each year.  The 2009 most cited article was Dr. A.D. Craig’s article entitled: “How do you feel—now? The anterior insula and human awareness”.Dr. Craig’........ Read more »

Caffeine makes us Crazy - or at least messes with our sleep

by mc in begin to dig (b2d)

i *love* good coffee. You? Do you know how you react to coffee? Do you find caffeine keeps you awake/alert? Yes? or maybe you find it doesn't affect your getting to sleep? We know that the magic in coffee is caffeine. Guess what? apparently whether or not we can fall asleep with caffeine is less of an issue than what it does to our sleep quality, in particular, our deep sleep state. That is, it ... Read more »

Babies, balls and creationists

by Daniel in Ego sum Daniel

A recently published study in PNAS explores how small babies relate order and disorder, or entropy, to the different types of things that may cause them. Amazingly, babies as small as 12 months old show some understanding of the difference between the deliberate and goal-directed "agents" that can cause order, such as a person, and those randomly acting inanimate objects that cannot, such as a bouncing ball. This means that we have some sort of general understanding that the way agents act on t........ Read more »

Cannabinoids in Huntington's Disease

by Neuroskeptic in Neuroskeptic

Two recent papers have provided strong evidence that the brain's endocannabinoid system is dysfunctional in Huntington's Disease, paving the way to possible new treatments.Huntington's Disease is a genetic neurological disorder. Symptoms generally appear around age 40, and progress gradually from subtle movement abnormalities to dementia and complete loss of motor control. It's incurable, although medication can mask some of the symptoms. Singer Woodie Guthrie is perhaps the disease's best known........ Read more »

Critiquing LaPlant et al, 2010, in Nature Neuroscience, Part 1. Let’s get this going.

by Scicurious in Neurotic Physiology

So Sci was sitting in a seminar the other day. We were mentioning this paper, some problems we had with it, some of the things we LIKED about it, and various approaches, etc, in our usual sciencey fashion. As the discussion got intense (in a good way), one of the PIs there leaned over and [...]... Read more »

The deaf have super vision, and other tales of neural plasticity

by Casey Rentz in Natural Selections

Ever been asked--if you had to choose, would you rather be deaf or blind? Its a futile hypothetical dilemma (as if the choice is ever available to anyone to make) that was probably first posed by some perpetually dramatic and irrevocably bored teenager OR--could it be--by a neuroscientist!

Perhaps we cherry pick vision and hearing for our speculative crises because they are particularly important to us and essential to achieve something our species is known for: high level mobility and naviga........ Read more »

Family Therapy for Adolescent Anorexia Nervosa

by William Yates, M.D. in Brain Posts

There is very limited research to guideline clinicians, patients and their family members in choosing the best treatments for anorexia nervosa and other eating disorders.  So when a well-designed and informative study is published it is noteworthy and important to review.   James Lock and colleagues summarized their findings from a randomized trial of family therapy versus individual therapy in a randomized controlled trial for adolescents with anorexia nervosa in the October 2010........

Can a magician trick people with autism?

by Jon Brock in Cracking the Enigma

Are people with autism susceptible to magical illusions? There are a number of reasons to suspect that they might not be.Firstly, magicians rely on misdirection. They'll use eye gaze and gesture to make sure the audience is looking one way, while they're secretly switching the cards or sneaking an elephant into a hat (or whatever it is they do). People with autism, it's argued, are less sensitive to these kinds of social cues, so perhaps they're not as easily misdirected.Second, as mentioned in........ Read more »

Location Location Location. Acupuncture and chronic shoulder pain – CAM or Sham?

by Lorimer Moseley in BodyInMind

Having written a number of posts on acupuncture (see here, here, and here) I guess my particular biases are reasonably apparent. So imagine my surprise when a large RCT published in the journal “Pain” reports a significant and substantial effect of Chinese acupuncture in comparison with sham acupuncture or conventional orthopaedic therapy for chronic shoulder [...]...

Friston and Freud

by Janet Kwasniak in Thoughts on thoughts

I have liked Friston’s ideas for some time, so what a shock it is to find him defending Freudian ideas. Naïve me, I thought that Freud’s model was dead in the water. Why? It is untested, does not fit with current evidence and, further, is probably untestable therefore not good science. It fails the Occam’s [...]... Read more »

Still More on Why the Tears of Strangers Are Only Water

by David Berreby in Mind Matters

This paper in the current issue of the journal Neuron claims to add some MRI findings to the evidence that human empathy and kindness stop at the border between "our group" and "others." Tania Singer, Grit Hein and their colleagues found that Swiss soccer fans feel more, and do more, about the suffering of fellow fans than they do for supporters of a rival team.
The researchers recruited 16 Zurich men from a local fan club, telling them they would be involved in a comparison of brain ........ Read more »

The evolutionary roots of laughter

by Christian Jarrett in BPS Research Digest

To evolutionary psychologists, the noise made by gorillas, chimps and bonobos when you tickle their feet is no laughing matter. These distinctive vocalisations suggest that rather than evolving separately, laughter evolved in a shared common ancestor before becoming tailored in each primate species, including humans.

To find support for this idea, Diana Szameitat and her colleagues scanned the brains of 18 men and women whilst they listened to the sound of human tickle-induced laughter as well ........ Read more »

Is Obesity like Drug Addiction? Maybe… The Role of BDNF

by neurobites in Neurobites

As a general rule, the cells of your body ought only grow, survive and proliferate when so directed by upstream messages, hormonal or otherwise.  In light of the supreme importance of proper and well-timed growth, it is these messaging systems that have recently become the stars of the show.  One area of particular importance is [...]...
