According to Dr. Stacey Spencer with Morris Psychological Group, working memory enables us to hold on to information long enough to manipulate it or use it to complete a task. Researchers estimate that the academic performance of as many as 10-15% of children is affected by problems with working memory. Parsippany, NJ (PRWEB) June 25, 2014 There are many reasons that children struggle in the classroom. Their ability to learn is affected by a wide range of emotional and cognitive factors...

Brain Geotags Memories

Brett Smith for redOrbit.com - Your Universe Online On Twitter, users can categorize their post by using a hashtag, which connects the tagged post to all other posts with the same identifier. A new study in the journal Science has found that our brains do something similar, by ‘geotagging’ our memories to a specific location. Using experiments involving study participants navigating through a virtual town, the team of American and German scientists concluded that brain cells encode...

Navigation Abilities Brain Structure

Brett Smith for redOrbit.com - Your Universe Online People who instantly know their way around after having traveled to a particular destination at least once have structurally different brains than those who require a map or GPS to navigate from place to place, new research shows. Doctoral researcher Joost Wegman at Radboud University Nijmegen in the Netherlands demonstrated that good navigators store relevant landmarks automatically along the way to their destination, while bad...

Cockatoos Know What Goes On Behind Barriers

University of Vienna How do you know that the cookies are still there although they have been placed out of your sight into the drawer? How do you know when and where a car that has driven into a tunnel will reappear? The ability to represent and to track the trajectory of objects, which are temporally out of sight, is highly important in many aspects but is also cognitively demanding. Alice Auersperg and her team from the University of Vienna and Oxford show that "object permanence"...

Having The Biggest Playlist Doesn't Make A Male Songbird The Brainiest Of The Bunch

Duke University "For songbirds, singing a lot of songs indicates a bird is smart, but that signal is not necessarily indicative of intelligence for everything," said Duke biologist Steve Nowicki. In a series of problem-solving tests with the birds, he and his colleagues found that the male song sparrows that sang the most songs learned to solve food-finding puzzles more slowly than the birds singing fewer songs. The results are the first to show that a larger song repertoire links to...

Studying How Brains Work When Bats Are On The Move

April Flowers for redOrbit.com - Your Universe Online Two new studies, published this week in Science, examine the mechanisms of animal navigation using bat models. RATS AND BATS The first study is the result of collaboration between University of Maryland (UMD), College Park and Boston University (BU). The findings, based on brain rhythms in bats and rats, challenges a widely-used model — based solely on rodents — of how animals navigate their environment. The study...

Regular game play improves performance on tasks that use similar mental processes as video game Playing video games for an hour each day can improve subsequent performance on cognitive tasks that use similar mental processes to those involved in the game, according to research published March 13 in the open access journal PLOS ONE by Adam Chie-Ming Oei and Michael Donald Patterson of Nanyang Technological University, Singapore. Non-gamer participants played five different games on their...

Jedidiah Becker for redOrbit.com — Your Universe Online In 2005, Norwegian researchers discovered a previously unknown type of neuron by placing electrodes deep within the cerebral cortex of rats. Dubbed “grid cells,” these specialized neurons were so named because they fire in distinct clusters, each of which constitutes the vertex of a grid-like pattern of equilateral triangles. This recurring triangular, lattice-like firing pattern is what distinguishes grid cells from other...

Brain Stimulation Could Boost Memory In Alzheimer's Patients
2012-02-10 05:10:41

Neuroscientists at UCLA have found a way to help improve a human's memory by stimulating a part of the brain. The research, published in the New England Journal of Medicine, could lead to a new method for boosting memory in Alzheimer's patients. The team focused on a brain site known as the entorhinal cortex during their study, which is an area considered to be the doorway to an area that helps form and store memories. "The entorhinal cortex is the golden gate to the brain's memory...

The hippocampus is an important brain structure for recollection memory, the type of memory we use for detailed reliving of past events. Now, new research published by Cell Press in the December 22 issue of the journal Neuron reveals characteristics of the human hippocampus that allow scientists to use anatomical brain scans to form predictions about an individual's recollection ability. The new research helps to explain why this relationship has been hard to find in the past and provides...
