8:21 PM | Vaccine against prion disease, not for humans… yet
Prions, misfolded proteins that wreak havoc on the brain, may have finally met their match. Best known for things like mad cow disease and possibly alzheimer’s disease scientists have had no luck stopping prions, until now. Researchers say that a vaccination they have developed to fight a brain-based, wasting syndrome among deer and other animals […]

9:13 PM | Beta-amyloid: the emperor really does have no clothes
Beta-amyloid: the emperor really does have no clothes: Yesterday, Roche announced its decision to discontinue its Phase 3 study of gantenerumab, its experimental anti-amyloid antibody, in early Alzheimer’s Disease. The study failed a futility analysis – the clearest possible evidence of a lack of signal. This marks the latest nadir for the amyloid hypothesis – the dominant collective understanding  of the molecular pathogenesis of Alzheimer’s Disease for more […]

10:56 AM | A clear, molecular view of how human color vision evolved
Many genetic mutations in visual pigments, spread over millions of years, were required for humans to evolve from a primitive mammal with a dim, shadowy view of the world into a greater ape able to see all the colors in a rainbow. Now, after more than two decades of painstaking research, scientists have finished a … Continue reading →

7:09 PM | How The Military Could Turn Your Mind Into The Next Battlefield
Long a staple of science fiction, the idea of creating weapons that can disrupt or alter the cognitive processes of enemy combatants is starting to become reality. Inspired by recent advances in neuroscience, the U.S. military is considering the potential for "neuro-cognitive weapons". Here's what you need to know about this fascinating and frightening prospect.Read more...

5:36 PM | Why Some People Are Better Navigators: Brain's 'Homing' Signal Identified
It's no secret that some people are better at navigating than others, but it has been unclear why. In order to successfully navigate to a destination, you need to know which direction you are currently facing and which direction to travel in. For example, 'I am facing north and want to head east'. It is already known that mammals have brain cells that signal the direction that they are currently facing, a discovery that formed part of the 2014 Nobel Prize in Physiology or Medicine to Professor […]

3:00 PM | Diabetes: High Blood Sugar In Young Children Linked To Slower Brain Growth
Young children with type 1 diabetes have slower brain growth compared to children without diabetes, finds a new study in Diabetes. The authors suggest that continued exposure to hyperglycemia, or high blood sugars, may be detrimental to the developing brain. They studied brain development in children ages four to nine years old with type 1 diabetes using structural magnetic resonance imaging (MRI) and cognitive tests to determine if abnormal blood glucose levels impact brain structure and […]

1:56 PM | Head Motion Biases Brain Structural Scans
A regular theme here at Neuroskeptic is the worrying issue of head movement during brain scans. We've seen that motion can alter measures of functional and structural connectivity, and that common approaches to dealing with this problem may be inadequate. Now a new study reveals that even measures of the gross structure of the brain can be biased by excessive motion: Head motion during MRI acquisition reduces gray matter volume and thickness estimates.

12:54 PM | Unbroken: what makes some people more resilient than others? | David Cox
The resilience of people like Louis Zamperini in the face of extraordinary trauma, as depicted in the film Unbroken, has lessons for psychiatrists treating post-traumatic stress disorder“We hit the water nose down. The plane exploded. I felt like someone hit me in the forehead with a sledgehammer. Everything almost stood still for a moment. I looked around and the plane was completely blown apart.”Louis Zamperini was talking to an interviewer on CBS in 1992. He died earlier this […]

4:20 PM | Histamine and Anorexia Nervosa
Most of us have at some point in our lives taken antihistamines–drugs that block the action of histamine (e.g., Claritin, Allegra)–to relieve allergy symptoms. And while histamine is best known for its role in the immune response, it also has many other important roles in the central nervous system. In the brain, histamine release is important for arousal (this is why antihistamines tend to make us drowsy). It has also been implicated in regulating appetite, taste […]

Egnor continues his dualist neuroscience denial in two follow up posts, mostly responding to PZ Myers’ take down of his original post. Egnor has also been writing separately about computers, arguing that they have no memory and will never be intelligent (have agency). In all of these posts Egnor is following the same basic intellectual [...]

9:42 AM | Dividing up the pie in relation to REF2014
OK, I've only had an hour to look at REF results, so this will be brief, but I'm far less interested in league tables than in the question of how the REF results will translate into funding for different departments in my subject area, psychology. I should start by thanking HEFCE, who are a model of efficiency and transparency: I was able to download a complete table of REF outcomes from their website here. What I did was to create a table with just the Overall results for Unit of Assessment 4, […]

11:30 PM | Migraine Headaches Linked To Double Risk For Bell's Palsy
Migraine headaches have been linked to double the risk of a nervous system condition that causes facial paralysis, called Bell's palsy, according to a new study published in the December 17, 2014, online issue of Neurology.  Bell's palsy affects between 11 and 40 per 100,000 people each year. Most people with Bell's palsy recover completely.  Headaches are the most common disorder of the nervous system, affecting about 12 percent of the US population. read more
