Children hear as much sophisticated information about animals when parents read picture book stories about animals as when they read flashcard-type animal vocabulary books, according to a new study from the University of Waterloo.

Neuroscientists have discovered a brain pathway that underlies the emotional behaviours critical for survival.

New research by the University of Bristol, published in the Journal of Physiology today [23 April], has identified a chain of neural connections which links central survival circuits to the spinal cord, causing the body to freeze when experiencing fear.

Understanding how these central neural pathways work is a fundamental step towards developing effective treatments for emotional disorders such as anxiety, panic attacks and phobias.

"Not tonight, dear, I have a headache." Generally speaking, that line is attributed to the wife in a couple, implying that women's sexual desire is more affected by pain than men's.

There's a new secret to get your child to behave at the dinner table—cut up their food and they'll relax.

A new Cornell study published in Eating Behaviors, found that when 6-10 year old children ate foods they had to bite with their front teeth— such as drumsticks, whole apples, or corn on the cob— they were rowdier than when these foods had been cut. "They were twice as likely to disobey adults and twice as aggressive toward other kids," said Brian Wansink, Professor and Director of the Cornell Food and Brand Lab.

An inexpensive glaucoma drug, when added to a weight loss plan, can improve vision for women with a disorder called idiopathic intracranial hypertension (IIH), according to a study funded by the National Institutes of Health.

Patients with arteriovenous malformations (abnormal connection between arteries and veins) in the brain that have not ruptured had a lower risk of stroke or death for up to 12 years if they received conservative management of the condition compared to an interventional treatment, according to a study in the April 23/30 issue of JAMA, a neurology theme issue.

(Chicago) – A recently FDA-approved device has been shown to reduce seizures in patients with medication-resistant epilepsy by as much as 50 percent. When coupled with an innovative electrode placement planning system developed by physicians at Rush, the device facilitated the complete elimination of seizures in nearly half of the implanted Rush patients enrolled in the decade-long clinical trials.

DALLAS – April 22, 2014 – Researchers at UT Southwestern Medical Center are making breakthroughs that could benefit people suffering from depression.

JUPITER, FL, April 22, 2014 – Scientists from the Florida campus of The Scripps Research Institute (TSRI) have identified a protein complex that plays a critical but previously unknown role in learning and memory formation.

The study, which showed a novel role for a protein known as RGS7, was published April 22, 2014 in the journal eLife, a publisher supported by the Howard Hughes Medical Institute, the Max Planck Society and the Wellcome Trust.

Almost one-third of adults in Canada have experienced child abuse — physical abuse, sexual abuse or exposure to intimate partner (parents, step-parents or guardians) violence in their home.

Chimpanzees may throw tantrums like toddlers, but their total brain size suggests they have more self-control than, say, a gerbil or fox squirrel, according to a new study of 36 species of mammals and birds ranging from orangutans to zebra finches.

A new study from North Carolina State University and the University of Toronto finds that people pay more attention to the upper half of their field of vision – a finding which could have ramifications for traffic signs to software interface design.

"Specifically, we tested people's ability to quickly identify a target amidst visual clutter," says Dr. Jing Feng, an assistant professor of psychology at NC State and lead author of a paper on the work. "Basically, we wanted to see where people concentrate their attention at first glance."
