Ambulance workers at risk of post-traumatic stress disorder
These were the findings of a study published today, Friday 10 September, in the British Journal of Clinical Psychology, by clinical psychologists Sue Clohessy and Professor Anke Ehlers of Oxford University. view more (1999-09-03)
How ants find their way
Ever wondered how ants find their way straight to the uncovered food in your kitchen? Now scientists have discovered how the humble wood ant navigates over proportionally huge distances, using just very poor eyesight and confusing and changing natural landmarks. view more (2006-10-18)
A natural chemical found in strawberries boosts memory in healthy mice
Mothers have long exhorted their children to eat their fruit and vegetables. But once kids are beyond mom's watchful eye, the hated greens often go the way of Barbie dolls and power rangers. Now, there's another reason to reach for colorful fruits past adolescence. view more (2006-10-18)
How 'hot' emotional brain interferes with 'cool' processing
For the first time, researchers have seen in action how the "hot" emotional centers of the brain can interfere with "cool" cognitive processes such as those involved in memory tasks. view more (2006-02-17)
Sleep strengthens your memory
Sleep not only protects memories from outside interferences, but also helps strengthen them, according to research that will be presented at the American Academy of Neurology's 59th Annual Meeting in Boston, April 28 - May 5, 2007. view more (2007-04-25)
'Speed of thought' guides brain's memory consolidation
Scientists at The University of Arizona have added another piece of the puzzle of how the brain processes memory. view more (2007-11-16)
The hormone of darkness: melatonin could hurt memory formation at night
What do you do when a naturally occurring hormone in your body turns against you? What do you do when that same hormone - melatonin - is a popular supplement you take to help you sleep? A University of Houston professor and his team of researchers may have some answers. view more (2007-11-16)
Brain structure associated with fear inhibition also may influence personality
The relationship between the size of a brain structure and the ability to recover from traumatic experiences also may influence overall personality type. view more (2005-11-28)
New record for information storage and retrieval lifetime advances quantum networks
Physicists have taken a significant step toward creation of quantum networks by establishing a new record for the length of time that quantum information can be stored in and retrieved from an ensemble of very cold atoms. view more (2008-12-08)
What memories are made of
Why is it that amnesia patients can't remember their names or addresses, but they do remember how to hold a fork? It's because memories come in many flavors, says Fred Helmstetter, professor of psychology at the University of Wisconsin-Milwaukee (UWM). Remembering what is not the same as remembering how. view more (2007-01-04)
Proteins anchor memories in our brain
A University of Utah study suggests that memories are held in our brains because certain proteins serve as anchors, holding other proteins in place to strengthen synapses, which are connections between nerve cells. view more (2006-11-22)
Scientists zero in on memory-related proteins at the core of Alzheimer's disease
New research sheds light on how the formation of long-term memories may be blocked in Alzheimer's disease. view more (2005-10-19)
Daytime sleep improves memory consolidation
A ninety minute daytime nap helps speed up the process of long term memory consolidation, a recent study conducted by Prof. Avi Karni and Dr. Maria Korman of the Center for Brain and Behavior Research at the University of Haifa found. view more (2008-01-08)
New research shows reactivating single memory does not affect associated memories
Researchers at a trio of universities have found that reactivating a specific memory does not affect associated or related memories, adding to our understanding of how memories are stored and influenced. view more (2006-02-14)
Sleep strengthens memories and makes them resistant to interfering information
Researchers have uncovered new evidence that sleep improves the brain's ability to remember information. Their findings demonstrate that memories of recently learned word pairs are improved if sleep intervenes between learning and testing and that this benefit is most pronounced when memory is challenged by competing information. view more (2006-07-11)
How the brain weaves a memory
Memories of events comprise many components-including sights, sounds, smells, and tastes. Somehow the many features of an episodic memory are woven together into a coherent whole, and researchers have had little understanding of how this binding takes place as the memories are processed by the brain's memory center, the hippocampus. view more (2006-11-09)
Illuminating Alzheimer's: Research sheds light on creatine's presence in brain
Alzheimer's disease is one of the most hauntingly destructive maladies to wreak havoc on humans. It robs children of parents and spouses of each other-with lifetimes of memories lost forever behind blank stares. view more (2005-12-22)
Neuronal Receptor Response May Help Explain Alzheimer's Memory Loss
Based on laboratory research, scientists at Georgetown University Medical Center have a new theory as to why people with Alzheimer's disease have trouble performing even the simplest memory tasks, such as remembering a family member's name. view more (2006-02-13)
Epsilon4 allele carriers show altered brain activity before onset of Alzheimer's symptoms
Healthy individuals who are at risk of Alzheimer's disease show reduced activity in the hippocampal region of the brain when performing tasks related to forming new memories. view more (2006-01-13)
Activation of a protein solidifies fear memory in the brain
When activated, a specific protein in the brain enhances long-term storage of fearful memories and strengthens previously established fearful memories. view more (2006-01-25)
