Journal Club: Wild mice actually enjoy running on exercise wheels

by GrrlScientist in Maniraptora

SUMMARY: Wild mice frequently and voluntarily run on an exercise wheel if provided access to them in nature, even in the absence of a food reward -- findings that dispel the idea that wheel running is an artefact of captivity, indicative of a neurotic or repetitive stereotyped behaviour that may be associated with poor welfare. ...

History of neuroscience: Fritsch and Hitzig and the motor cortex

by neurosci in Neuroscientifically Challenged

The motor cortex (in red)

Neuroscience now views the cerebral cortex as a region of the brain that is essential for sensation, movement, and the heightened level of cognition we associate with humans as compared other animals. In the 1700s, however, many scientists considered the cortex to be a functionally insignificant outer shell of the brain. This corresponds to its original meaning when translated from Latin, which is "bark" (as in tree bark).By the 18........ Read more »

Did Dogs, Cats and Cows Predict the M9 Earthquake in Japan in 2011?

by CAPB in Companion Animal Psychology Blog

Is it possible that animals had advance warning of the Tohoku earthquake?Photo: Paul Atkinson / ShutterstockThere have long been reports of animals behaving strangely before large quakes, including an account of snakes, weasels and rats leaving home prior to an earthquake in Greece in 373BC. But there is still a lack of scientific evidence.  A new study in Japan investigates pet owners’ reports of cat and dog behaviour, and changes in dairy milk production, before the magnitude 9 earthqua........

Can cognitive training boost self-control?

by Christian Jarrett in BPS Research Digest

I’m someone who when sat in front of a fast food menu will always make a beeline for the most artery-clogging burger and a large fries. At the same time, I’m fascinated by those around me who will happily order “regular” or “small” servings (or even the dreaded “healthy” alternative). How do they resist temptation? What distinguishes these intriguing individuals from the rest of us – and, by the way, where can I get some more of that prized self-control?I’m not alone. Underst........ Read more »

Vaccines not associated with autism: a meta-analysis

by Paul Whiteley in Questioning Answers

I'm gonna warn you that this is probably the longest of my ramblings so far covering one of the most controversial topics linked to autism in recent years... so it might be best if I provide you with some music to start with (Pink Floyd and Breathe) and suggest that you get yourself comfortable.The singer @ Wikipedia So then..."Findings of this meta-analysis suggest that vaccinations are not associated with the development of autism or autism spectrum disorder".That was the conclusion ........

Why Women are Better CEOs, Presidents, and Prime Ministers

by Jeremiah Stanghini in Jeremiah Stanghini

New research shows that women are far better at handling stress than men. I suppose that’s not a newsflash as most people already think that’s true, but consider the way in which this study frames it [Emphasis added]: We consistently … Continue reading →... Read more »

A replication tour de force

by Christian Jarrett in BPS Research Digest

In his famous 1974 lecture, Cargo Cult Science, Richard Feynman recalls his experience of suggesting to a psychology student that she should try to repeat a previous experiment before attempting a novel one:“She was very delighted with this new idea, and went to her professor. And his reply was, no, you cannot do that, because the experiment has already been done and you would be wasting time. This was in about 1947 or so, and it seems to have been the general policy then to not try to repeat ........ Read more »

The neuroscience of obsessive-compulsive disorder

by neurosci in Neuroscientifically Challenged

As awareness of obsessive-compulsive disorder (OCD) has grown over the years, so has the degree to which the disorder is misunderstood. For example, one common misperception is that individuals who suffer from OCD all engage in repetitious rituals like hand-washing, repeatedly checking the locks, or flicking the light switch on and off a specific number of times. While some people with OCD do experience ritualistic compulsions, this is not a necessary component of an OCD d........ Read more »

Insufficient evidence that mindfulness helps the mindful most

by Katharine Blackwell in Contemplating Cognition

Every now and then when I post about the latest in mindfulness research, I wonder if I am still properly objective. As a fan and (sometimes) practitioner, I may be in the same position as many of my students where I just want to believe the cool results and don’t keep any eye out for flaws an inconsistencies. The good news today is that I have determined that there are still some mindfulness studies that I will toss over my shoulder; the bad news, of course, is that there are such studies ........

Drunk Fish Convince Sober Ones to Follow Them Around

by Elizabeth Preston in Inkfish

It’s a good thing fish can’t operate a vehicle. Not only do drunk zebrafish swim extra fast, but they somehow get all the sober fish to follow them. Essentially, a drunk fish becomes the designated driver for the whole group. Although a fish is only marginally like a human, fish can be convenient subjects for […]The post Drunk Fish Convince Sober Ones to Follow Them Around appeared first on Inkfish.... Read more »

Fat bias in the workplace

by Rita Handrich in The Jury Room

It is likely not a surprise to you that there is a significant public bias against the obese. Frequent flyers are familiar with the feeling of dread as a morbidly obese passenger approaches your row and seems to slow down. But fat bias doesn’t just happen in confined spaces. Workplace incivility is often directed at […]

Depression is a growing public health concern, affecting 1 in 9 people at some point in their lives, and with a third of sufferers experiencing little or no benefit from medication. The World Health Organization predicts that by 2020 depression will become the second leading cause of disability worldwide. By 2026 it is expected to afflict nearly 1.5 million people in the UK, costing the economy more than £12bn every year.Faced with this crisis, scientists have looked for alternative solutions t........

ADOS via YouTube for autism 'triage'?

by Paul Whiteley in Questioning Answers

The paper by Vincent Fusaro and colleagues [1] and some accompanying press attention about this study caught my eye recently. Based on an analysis of 100 home videos posted on YouTube, some tagged with words leading to the assumption of the presence of autism, undergraduate researchers used scoring measures from the gold-standard autism assessment schedule ADOS (Autism Diagnostic Observation Schedule) to quite accurately grade whether children appearing in the videos could be classified as autis........

Does Gamma tACS Really Induce Lucid Dreaming?

For a strong mind, let the heart lead

by Teodora Stoica in CuriousCortex

It's wedding season. The perfume of fresh cut flowers scents the air, lingering as guests arrive to celebrate the highly anticipated event. As the music plays softly, she floats down the aisle and lovingly exchanges vows with her beloved - revealing the positive impact each has had on the other. As an observer of the couple's courtship, you might silently concur how truly different each has become since falling in love, and wonder why. Only two years ago, the groom’s snarky comm........

Nearly 13% of children with a DSM-IV diagnosis?

I had tweeted about the paper by Sandra Petresco and colleagues [1] (open-access here) a while back as being the source of the sentence: "Nearly 13 % of the children presented a psychiatric diagnosis according to DSM-IV" based on their analysis of the Pelotas Birth Cohort [2] in Brazil.Aleijadinho: Angel of the Passion @ Wikipedia The crux of the Petresco paper was that by looking at all the children, or at least the majority of children, born during 2004 in the city of Pelot........
