Making Memories Last
Stowers researchers discovered that a prion-like protein plays a key role in storing long-term memories. Memories in our brains are maintained by connections between neurons called “synapses”. But how do these synapses stay strong and keep memories alive for decades? [Read More]
Study: Men at Higher Risk for Mild Memory Loss than Women
Men may be at higher risk of experiencing mild cognitive impairment (MCI), or the stage of mild memory loss that occurs between normal aging and dementia, than women, according to a study published in the January 25, 2012, online issue of Neurology®, the medical journal of [Read More]
Genetic Study Offers Clues to How Intelligence Changes Through Life
Scientists have estimated for the first time the extent to which genes determine changes in intelligence across the human life course. The study found that genetic factors may account for about 24 per cent of changes in intelligence between childhood and old age. The [Read More]
The Illusion of Courage: New Research Explains Why People Mispredict Their Behavior in Embarrassing Situation
Whether it’s investing in stocks, bungee jumping or public speaking, why do we often plan to take risks but then “chicken out” when the moment of truth arrives? In a new paper in the Journal of Behavioral Decision Making, scientists from the University of [Read More]
Cognitive Decline Can Begin as Early as 45, Warn Experts
The brain’s capacity for memory, reasoning and comprehension skills (cognitive function) can start to deteriorate from age 45, finds research published in the BMJ today. Previous research suggests that cognitive decline does not begin before the age of 60, but this view [Read More]
UCLA Neuroscientists Demonstrate Crucial Advances in Brain Reading
Innovative machine learning method anticipates neurocognitive changes, similar to predictive text-entry for cell phones, internet search engines At UCLA’s Laboratory of Integrative Neuroimaging Technology, researchers use functional MRI brain scans to observe brain [Read More]
Babies Remember Even as They Seem to Forget
Fifteen years ago, textbooks on human development stated that babies 6 months of age or younger had no sense of “object permanence” – the psychological term that describes an infant’s belief that an object still exists even when it is out of sight. That [Read More]
Neuroscientists Boost Memory Using Genetics and Memory Enhancing Drug
When the activity of a molecule that is normally elevated during viral infections is inhibited in the brain, mice learn and remember better, researchers at Baylor College of Medicine reported in a recent article in the journal Cell. “The molecule PKR (the [Read More]
HC: Woman with Amnesia Unable to Hold a Single Face in Short-term Memory … Unless it’s Paris Hilton
Study shows intact memory for familiar information, despite memory deficit A 22-year-old woman known as “HC” with amnesia since birth as a result of developing only half the normal volume of the hippocampus in her brain, has demonstrated to scientists that the [Read More]
Neuroscientists Show Activity Patterns in Fly Brain are Optimized for Memory Storage
We know from experience that particular smells are almost inseparable in our minds with memories, some vague and others very specific. The smell of just-baked bread may trigger an involuntary mental journey, even if for a moment, to childhood, or to a particular day during [Read More]
