How Knowledge Can Make You Stupid
by Eric Horowitz in peer-reviewed by my neurons
The human ability to infer what other people are thinking is a big reason we’re able to understand and cooperate with others. Along with the ability to take pictures of our food, it’s what separates us from lesser primates. But we’re not born with this ability. Experiments involving what’s called the “change-of-location” or “false-belief” task show [...]... Read more »

Vision is for decision
by neuroecology in Neuroecology
When we typically think of how decision-making works in the brain, we think of new input coming in, perhaps through the eyes or ears, being processed in the relevant sensory areas, and then sent to the ‘decision-making’ areas (the basal ganglia, prefrontal cortex, or anterior cingulate cortex) where this information is used to make a decision. [...]... Read more »

A true paleo diet: dinosaurs eating fish
by Zen Faulkes in NeuroDojo
There’s been a lot of talk about “paleo diets”, but here we have the real deal. A meal caught in the middle of digestion in a dinosaur.
Microraptor gui was introduced back in 2003, and immediately attracted attention because of the its feathers, particularly lots of long, prominent feathers on its hind legs, so unlike any bird or other flying beast we know of. There is good evidence (though disputed) that it was a glossy, black animal, rather like the grackles that hang around my campus.

Are some languages easier than others?
by Richard Kunert in Brain's Idea
‘Long time no see’ is something I heard repeatedly in Britain even though it totally violates all the English grammar I learned at school. Clearly, Brits should correct this expression originating from Chinese Pidgin English rather than adopt it. The reason it entered common usage anyway is at the heart of why you might find [...]...

Metaphors for Musical Pitch Vary, but the Basic Principles Are the Same

DTI Identifies Brain Aging Changes
by William Yates, M.D. in Brain Posts
Brain white matter plays a key role in connecting functional brain areas. These connections are required for complex brain processing required for memory and executive functions, i.e planning and problem solving.Diffusion tensor imaging (DTI) is a relatively recent brain imaging tool that provides a method of analyzing regional human white matter function. Additionally, when DTI is paired with cognitive testing it allows for study of the brain regions and circuits responsible for spe........ Read more »

Update on Badgers, Basketmakers, and Boats
by Katy Meyers in Bones Don't Lie
In archaeology, we are constantly getting updates on old material. When results are released, it isn’t always when the study itself is complete. Further, new methods or techniques may lead to re-analysis of older sites and remains, revealing new conclusions. Updates on old topics can cause increased debate, or end arguments completely depending on the … Continue reading »... Read more »

Discussion of Dogs’ Behavioural Problems at the Vet
by CAPB in Companion Animal Psychology Blog
Surprisingly little is known about where people seek advice when their dog has a behavioural problem such as aggression, soiling in the house, or fear of fireworks. One place to try might be the vet, but do veterinarians talk to their clients about behavioural problems during the annual consultation for vaccinations?A study just published in the Veterinary Record by Roshier and McBride recorded vet consultations and transcribed the conversations for analysis.

A Death Apple A Day Keeps…..
by Mark Lasbury in As Many Exceptions As Rules
Plants are great poison generators. Their toxins can affect skin, heart function, nerve function, or muscle function. In many cases plants make more than one toxin. The manchineel tree for instance, can induce everything from blindness to blisters to swelling of larynx. Oleander is toxic, but for different reasons, and urushiol from poison ivy induces a type IV hypersensitivity. Sounds like none of this is good for humans, but new research studies are showing medicinal values for these plant tox........ Read more »

Simple Jury Persuasion: The Sunshine Samaritan Effect
by Doug Keene in The Jury Room
If you want to prevail at trial, would it be useful to be able to control the weather? New research would say it depends on whether you want the jurors to help the plaintiff or defendant or not. Seriously? Seriously. It’s called the Sunshine Samaritan Effect. “Your Honor, I’d like to recess until the sun [...]

Recent Trauma and Acute Infection Linked with Stroke In Children
by Vivek Misra in Beautiful Mind
Research has demonstrated that experiencing head or neck trauma or minor acute infections such as influenza can increase risk for stroke among adults. Inflammation in the CNS or in the periphery may be a risk factor for the initial development of cerebral ischemia. Fullerton (University of California, San Francisco, USA) and colleagues hypothesized that trauma and acute infections are independently associated with childhood arterial ischemic stroke (AIS). Researchers carried out a case........ Read more »

Coaches Influence Team and Player Adherence to Injury Prevention Programs
by Kyle Harris in Sports Medicine Research (SMR): In the Lab & In the Field
Take Home Message: Coaches who are well trained to implement injury prevention, warm-up programs are as effective as the supervision of a physiotherapist at training sessions.
Injury prevention programs typically are multifaceted warm-up programs which focus on neuromuscular recruitment. While many programs exist it is difficult to assess their efficacy due to varying levels of adherence to the injury prevention program. Therefore, Steffen and colleagues completed a cluster-randomized trial t........ Read more »
