The Dodo is Dead, Long Live the Dodo!

by Laelaps in Laelaps

The Dodo, Didus, is a bird that inhabits some of the islands of the East Indies. Its history is little known; but if the representation of it be at all just, this is the ugliest and most disgusting of birds, resembling in its appearance one of those bloated and unwieldy persons who by a long [...]...

Synthetic Biology, or Science Fiction?

On the nature of sensorimotor integration for speech processes

by Greg Hickok in Talking Brains

For the last few years I have been thinking a lot about a few different things: What specifically is our proposed dorsal stream doing? How does the motor system contribute to speech perception? What is the relation between sensorimotor processes used during speech production (e.g., feedback-based motor control models) and purported sensorimotor processes in speech perception? How do computational models of speech production (e.g., feedback control models, psycholinguistic models, neurolinguist........ Read more »

Functional Brain Imaging in the Mouse

by William Yates, M.D. in Brain Posts

Functional magnetic brain imaging (fMRI) provides a new tool for understanding the brain in humans. It is already been helpful in understanding connectivity and focal brain region functions across a variety of domains, i.e. vision, hearing, motor function, somatic sensation and emotional processing. However, functional brain imaging in the mouse model has trailed structural brain imaging development. So why would fMRI be a potentially useful research tool in mice? There are several reasons......... Read more »

Is Vilyuisk encephalitis a viral disease?

by Vincent Racaniello in virology blog

A type of human encephalitis – an infection of the brain – has been known to affect the indigenous people living in the Sakha Republic of Russia since the mid-1800s. The available clinical and epidemiological evidence suggests that the disease is caused by a pathogen, but proving this has been difficult. The disease is called [...]... Read more »

Pregnancy timing and autism risk: Wait 3 years between births to lower your child’s risk?

by Nestor Lopez-Duran PhD in Child-Psych

The results of last week’s poll are in and the autism article won by a wide margin. So here are some thoughts on the recent pregnancy timing and autism study. A team from Columbia University was interested in examining the link between Inter Pregnancy Interval (e.g., time between pregnancies; IPI) and autism. IPI is important [...]... Read more »

Genetics and Pain

by Elaine Westwick in The Stuff of Life

Last year there was a post on Body in Mind in response to an article published on the genetics of chronic pain. With refreshing honesty the author admitted he “was going to write a blog-post on it and then I read it and I was too intimidated by it.”

I had a look at the paper, with my molecular biology background, it wasn’t too scary. I was interested in the original blog post as it intersects many parts of my life. First my original training as a biochemist, second my curren........ Read more »

Phrenology, Then and Now

by The Neurocritic in The Neurocritic

In the November 2010 issue of Perspectives in Psychological Sciences, a Special Section on "Neuroimaging: Voodoo, New Phrenology, or Scientific Breakthrough?" (Diener, 2010) looks back at the infamous paper by Vul et al. (2009) and forward into the future. In one of the articles, an extended analogy is made between modern neuroimaging and the phrenology of yore (Poldrack, 2010):Imagine that fMRI had been invented in the 1860s rather than the 1990s. Instead of being based on modern cognitive p........ Read more »

A spectacular new fossil provides insight on the sex lives of pterosaurs, part I

by Darren Naish in Tetrapod Zoology

We know all too little about the biology and behaviour of the pterosaurs, the amazing, often bizarre flying reptiles of the Mesozoic Era. Most of our ideas - about feeding behaviour, locomotion, physiology and social and sexual behaviour - are inferences based on bones, or inferences based on interpretations of the bones. A new paper - published just a few weeks ago by Junchang Lü, David Unwin and colleagues in the journal Science - describes what might be one of the most interesting pterosau........ Read more »

It Will Take More Than Information To Change Behaviour

by Arya M. Sharma in Dr. Sharma's Obesity Notes

Yesterday, I applauded the announcement by Canada’s leading beverage producers to clearly post calories on their products.
But I also warned that without educating Canadians on how to use this information, this ‘clarity on calories’ (as this initiative is called) may not quite produce the expected results.
So how effective are education campaigns on eating healthier and [...]... Read more »

What big eyes you have!

by Zen Faulkes in NeuroDojo

“My goodness, Gammarus, what big eyes you have!”

There are a lot of possible answers to Red Riding Hoods question. You might have big eyes to help you navigate in the world, to find resources, mates, and all sorts of things. If you see variation in eye size in populations, it will be tricky to figure out what the selection pressure on eye size is, because eyes do so many different jobs.

In the case of one amphipod crustacean, the answer to Red’s question seems to be:

“All the better ........ Read more »

Just a heartbeat away from one’s body

by Lorimer Moseley in BodyInMind

Body image means different things to different people. To many it refers to how one feels about one’s body.  To us, it refers to how one’s body feels to oneself and how one perceives its shape, orientation, agency and ownership.  Hopefully you can see that body image is critical to pain, because pain is, we [...]...

by Erin Campbell in HighMag Blog

There are times when you finish reading a paper and you push it in front of your labmates and ask, “Did you seeeeee this?!” Hopefully, your labmates will indulge you as you do an interpretive dance explaining the coolness of the paper. If I were still in a lab, the images and paper in today’s post would be thrust in front of my labmates….great results and killer microscopy!
