How reward and daytime sleep boost learning

by Dr. Jekyll in Lunatic Laboratories

A new study suggests that receiving rewards as you learn can help cement new facts and skills in your memory, particularly when combined with a daytime nap. The findings from the University of Geneva reveal that memories associated with a reward are preferentially reinforced by sleep. Even a short nap after a period of learning is beneficial....

How plants turn into zombies

by Dr. Jekyll in Lunatic Laboratories

It begins as a fairy tale which later turns into a horror story: Lusciously flowering plants, surrounded by a large number of insects. Usually, both sides profit from the encounter: Feasting on the plant juice and pollen, the insects pollinate the flowers and thus secure the survival of the plants. However, sometimes the insects – in this case a certain species of leafhoppers – can bring disaster to the plants, which they are not able to overcome.... Read more »

‘Paleo’ style sleep? Think again…

by Dr. Jekyll in Lunatic Laboratories

It's tempting to believe that people these days aren't getting enough sleep, living as we do in our well-lit houses with TVs blaring, cell phones buzzing, and a well-used coffee maker in every kitchen. But new evidence reported in the Cell Press journal Current Biology on October 15 shows that three ancient groups of hunter-gatherers--living in different parts of the world without any of those trappings of modern life--don't get any more sleep than we do....

What metabolism could reveal about aging and mortality

by Dr. Jekyll in Lunatic Laboratories

Why some people live much longer than others is an enduring mystery. Now, based on a study of a worm, scientists are getting one step closer to understanding longevity. They report that the metabolic profiles of the worms could accurately predict how long they would live and that middle age could be a key turning point.... Read more »

by Dr. Jekyll in Lunatic Laboratories

Using advanced brain imaging, researchers have matched certain behavioral symptoms of schizophrenia to features of the brain’s anatomy. The findings, at Washington University School of Medicine in St. Louis, could be a step toward improving diagnosis and treatment of schizophrenia.... Read more »

Supercoiled DNA is far more dynamic than the ‘Watson-Crick’ double helix

by Dr. Jekyll in Lunatic Laboratories

Researchers have imaged in unprecedented detail the three-dimensional structure of supercoiled DNA, revealing that its shape is much more dynamic than the well-known double helix.

Various DNA shapes, including figure-8s, were imaged using a powerful microscopy technique by researchers at the Baylor College of Medicine in the US, and then examined using supercomputer simulations run at the University of Leeds.... Read more »

Immune gene prevents Parkinson’s disease and dementia

by Dr. Jekyll in Lunatic Laboratories

Blood clotting protein triggers immune attack on the brain

by Dr. Jekyll in Lunatic Laboratories

A new study from the Gladstone Institutes shows that a single drop of blood in the brain is sufficient to activate an autoimmune response akin to multiple sclerosis (MS). This is the first demonstration that introduction of blood in the healthy brain is sufficient to cause peripheral immune cells to enter the brain, which then go on to cause brain damage....

Can Google Books Really Tell Us About Cultural Evolution?

by Neuroskeptic in Neuroskeptic_Discover

In 2009, Google made available Google Books (also known as the Ngram corpus), a database that now includes over 8 million books from libraries around the world. The books comprise a collection of words (over 500 billion English words) and phrases and this dataset is freely available for research use. The Books corpus allows researchers to examine changes in the frequency of word use in books over time, dating back to 1800.



This has led a lot of striking findings. So for instance, it has b... Read more »

Pain is in the brain

by Dr. Jekyll in Lunatic Laboratories

Chronic pain results from disease or trauma to the nervous system. Damaged nerve fibres with heightened responses to normal stimuli send incorrect messages to pain centres in the brain. This phenomenon, called “peripheral and central sensitization” is one of the key mechanisms involved in the condition which touches people with diabetes, cancer, and those suffering from multiple sclerosis, among others....

Sex change hormonal treatments alter brain chemistry

by Dr. Jekyll in Lunatic Laboratories

Hormonal treatments administered as part of the procedures for sex reassignment have well-known and well-documented effects on the secondary sexual characteristics of the adult body, shifting a recipient’s physical appearance to that of the opposite sex. New research indicates that these hormonal treatments also alter brain chemistry.... Read more »

Social Class Differences in Mental Health: Do Parenting Style and Friendship Play a Role?

by Mark Rubin in Mark Rubin's Social Psychology Research Blog

It is now well-established that social class is positively related to mental health. However, researchers remain unclear about the specific processes that underlie the relation between social class and depression. In some recent research, we investigated the potential roles of parenting style and friendship in explaining the relationship between social class and mental health....

Parents influence children’s play of violent video games

by Dr. Jekyll in Lunatic Laboratories

Parents who are more anxious and emotional can impact the amount of violent video games their children play, according to new consumer research from Iowa State University. Russell Laczniak, a professor of marketing and the John and Connie Stafford Professor in Business, says given the harmful effects of violent video games, he and his colleagues wanted to better understand how parents influence children’s behavior....

American placebo – An increase in the placebo response, but only in America?

by Dr. Jekyll in Lunatic Laboratories

A new study finds that rising placebo responses may play a part in the increasingly high failure rate for clinical trials of drugs designed to control chronic pain caused by nerve damage. Surprisingly, however, the analysis of clinical trials conducted since 1990 found that the increase in placebo responses occurred only in trials conducted wholly in the U.S.; trials conducted in Europe or Asia showed no changes in placebo responses over that period....

Brain networking: behind the cognitive control of thoughts

by Dr. Jekyll in Lunatic Laboratories

The human brain does not come with an operating manual. However, a group of scientists have developed a way to convert structural brain imaging techniques into “wiring diagrams” of connections between brain regions. Three researchers from UCSB’s Department of Psychological & Brain Sciences — Michael Miller, Scott Grafton and Matt Cieslak — used the structure of neural networks to reveal the fundamental rules that govern which parts of the brain are most able to exert cognitive control ........
